What is SEO? Master the core concepts in 3 minutes

SEO (Search Engine Optimization) is a marketing strategy that adjusts the website content and technical architecture to allow web pages to obtain higher rankings in Google's natural search results. Research shows that 81% of consumers will search for information online before shopping. This is a critical opportunity for companies to increase brand exposure and obtain free traffic through SEO.

Why do we need SEO? Two practical reasons

• ✓ Accurately meet the needs: When users actively search, your information appears
• ✓ Long-term investment: High-quality rankings can bring continuous traffic, unlike advertising which will disappear after the ad is stopped.

Quickly understand how SEO works

There are two main ways to get exposure on Google:

• Paid advertising (SEM)
  • Immediately displayed in the advertising area
  • Ongoing payment for clicks
  • Suitable for short-term promotions
• Organic search (SEO)
  • Appears in the general results area
  • 3-6 months optimization period required
  • Long-term free traffic source

Summary of SEO core value in one sentence

"Build a website that is recognized by Google and loved by users, so that when the target customers need you, they will naturally find you."

In the era of AI technology, friends engaged in SEO should pay special attention to:

Content construction is still the core key of SEO optimization. According to Google's official SEO guidelines updated in 2025, content that is "completely automatically generated by AI" will not be considered high-quality content. Therefore, even if AI can be used to assist in writing the first draft, it still needs to be written and optimized by an editor with marketing expertise to ensure that the content is practical and truly helpful to users.

Based on our practical experience, AI-generated content still has many flaws, such as grammatical errors, inaccurate information, unclear logic, etc. Therefore, if you want to use AI to assist in content production, please be sure to conduct manual review and proofreading to ensure quality.

What is the difference between "SEM" and "SEO" that we often hear?

SEM (Search Engine Marketing) refers to all marketing methods conducted through search engines，including "SEO (Search Engine Optimization)" in natural search results and paid advertising such as "PPC (pay-per-click keyword advertising)". Both fall under the category of SEM.

However, in practical workplace situations, many people simply refer to “keyword advertising” as SEM. If you are confused about the definitions of these terms, it is recommended to refer to this in-depth analysis article.

You may ask: So which one is better, SEO or keyword advertising? Is it okay if I only do SEO and don’t run any advertising?

In fact, there is no absolute answer, because the marketing goals and benefits of SEO and keyword advertising are different (see the comparison table below). It is recommended to first evaluate the brand’s current resources and goals, and then decide how to plan marketing. In practice, we usually recommend a "dual track approach" to achieve more complete and stable growth in SEM.

Why is SEO optimization important? What are the benefits of using SEO marketing?

Of course, some people will ask: Why is SEO optimization so important?

Whether modern people are feeling unwell, encountering difficulties at work, or looking for a restaurant to eat at on the weekend, the first thing they do is open Google to search. This also means that there is huge market potential behind "search marketing".

In addition to the advantage of huge search volume, SEO search engine optimization has many practical benefits:

• Long-term effective exposure
  Unlike general advertising that requires an ongoing budget, SEO exposure has long-term benefits. As long as the website can appear stably in Google search results, it will usually not be removed in the short term and will continue to bring in traffic.
• Accurately reach potential customers
  SEO can target specific keywords so that users who search for these keywords can actively find your content. This means they already have a certain level of demand or interest in your product or service, and the chances of conversion are higher.
• Build brand trust and awareness
  When your website content continues to appear in user search results and provides useful information, it will naturally establish a sense of professionalism and trust in the minds of potential customers and further enhance your brand image.
• Comprehensively improve the quality of the website
  The SEO optimization process usually improves the overall quality of the website at the same time. In order to meet Google's standards for high-quality websites, we will optimize website speed, security, content depth, mobile device compatibility, etc., which will not only help SEO, but also make the overall user experience better.

Can companies optimize SEO themselves? What to do?

Many companies often ask: Can we do SEO ourselves? The answer is – of course!

In-house SEO is generally encouraged as long as the following key conditions are met:

• ➊ SEO Expert: Leader in Strategic Planning
  The company must have at least one professional who is familiar with SEO. He needs to understand the operating logic of search engines, grasp the changes in Google algorithms, and be able to formulate appropriate SEO strategies and lead the team to optimize the website. Whether it is internal training, hiring professionals, or seeking assistance from external consultants, all are feasible options.
• ➋ Website optimization PM: master progress and track results
  SEO optimization is not just about text optimization, it also involves aspects such as website speed, navigation structure, page experience, etc. Therefore, a PM who is familiar with website operations and SEO concepts is needed to assist in project planning, cross-departmental coordination, and effectiveness monitoring.
• ➌ Web engineer: Technical support is essential (applicable to customized websites)
  If you are using a platform such as SHOPLINE or Shopify, there will be relatively few technical issues. However, if it is a customized website, you may need to adjust the code, URL structure or page rendering during the SEO optimization process. At this time, a web engineer will be needed to support the execution of technical SEO.
• ➍ Content Marketer: Write valuable content
  Content is the core of SEO. Search engines value "content that is helpful to users", so companies need marketing or copywriting personnel with content planning and writing capabilities to continuously produce high-quality content for the website and accumulate natural traffic and brand influence.

If the business itself has the above conditions, then it has the ability to optimize SEO on its own.
However, if resources are limited, you can also choose to slowly develop an SEO team internally, or cooperate with an external professional consulting company to gradually build up the search competitiveness of the website.

Before learning SEO, you need to understand these basic concepts first!

Before you start learning the details of SEO, it is important to establish some core concepts first, which will make your understanding and implementation smoother:)

How does Google search engine work?

The operation principle of search engines can be simply divided into the following 4 steps:

• 1:Crawl: Google crawlers visit your website
  Google has an automatic program called "Crawler", which, like a library administrator, crawls every public web page on the Internet and reads website information, including web page content, HTML code, images, etc.
• 2:Index: Create a website database
  After the crawler collects the data, it will send your website content back to Google's database for "indexing". You can imagine that Google is building a large web encyclopedia, categorizing and organizing your web pages into it to facilitate future searches.
• 3:Analysis (Search Intent): Understand what the user is looking for
  When a user enters a keyword, Google will determine the "search intent" behind the keyword based on past data, semantic analysis, and other methods - for example, is it to buy something? Check knowledge? Watch a video?
• 4:Ranking: Determine who is at the front
  Finally, it is the "ranking" that we care about most!
  Google will evaluate which page best meets the search requirements based on a series of algorithms (including website content quality, speed, security, mobile friendliness, user experience, etc.) and rank the position on the search results page (SERP) based on these scores.

Simply put, making your website found, understood, indexed, and ranked high by Google is the essence of SEO!

What is Google Algorithm? Why is it important to understand SEO?

The reason why our website can be found, indexed, and even ranked at the top of the search result page (SERP) by Google is all due to the operation of the Google search algorithm behind it!

Google has dozens of algorithms, each responsible for different scoring items: such as user experience, website content quality, website security, link structure, etc.
The focus of SEO is to make our website meet the expectations and scoring standards of these algorithms.

Understanding algorithms has two major benefits:

• ✓ You can grasp the correct direction of SEO optimization
• ✓ When Google makes updates, you can quickly adjust and avoid ranking fluctuations

What is the difference between white hat, gray hat and black hat SEO? Beginners must know!

In the process of learning SEO, you may hear many people mention the terms "white hat", "black hat", and "gray hat". These are actually descriptions of different SEO operations, and each method will bring different levels of risk and reward to the website.

White Hat SEO

Legal, safe and long-term business approach

What is White Hat?
White hat SEO is an operation method that fully complies with Google's official guidelines, emphasizes "user-centricity", and pursues the overall improvement of website quality and experience.

Common white hat practices:

• Optimize website architecture and speed
• Write original, valuable content
• Reasonable configuration of title and description (Title / Meta)
• Enhanced mobile friendliness
• Improve user retention time and interaction rate

Suitable for:
Those who want to operate a brand or e-commerce brand for a long time and value stable ranking and reputation.

Black Hat SEO

High risk of cheating and violation

What is Black Hat?
Black hat SEO is a method of quickly manipulating rankings by violating Google's regulations. Although it is effective in the short term, once detected by the algorithm, it is likely to be punished or even removed from the entire site!

Common black hat techniques:

• Keyword Stuffing
• Hide text, hide links
• Buying a large number of low-quality backlinks
• Plagiarizing or substantially copying content
• Fake clicks and traffic manipulation

The risk is extremely high and it is strongly not recommended!

Grey Hat SEO

Walking on the edge, effective in the short term but risky

What is Gray Hat?
It is between the white hat and the black hat. On the surface, there is no violation, but in fact, it may be crossing the red line. Such tactics may sometimes be deemed acceptable by the algorithm, but may sometimes be targeted.

Common gray hat techniques:

• Rewrite other people's articles and use AI to generate a lot of content
• Deliberately exchange backlinks
• Use self-media groups or station groups to operate traffic
• Fine-tune title/content to induce clicks

Suitable for:
Advanced operators, but requires a high level of SEO risk awareness.

Conclusion: For long-term brand management, it is recommended to choose white hat SEO

Although black hat or gray hat SEO may show results in the short term, in the long run, it is white hat SEO that can truly enable a website to grow steadily and gain trust.

Just remember this sentence:
“Google also wants good websites to be seen, and following its logic is the best SEO strategy.”

SEO Self-Learning Map: The First Step to Building a Solid Foundation

Learning SEO can often feel daunting, not only because it is a large field with a wide range of implications, but also because it is a relatively opaque field. Although Google has released some instructions for its search algorithm, the overall structure is still incomplete. In addition, most information on the Internet is scattered and fragmentary, so beginners often feel confused and frustrated when searching for information and understanding content.

Even so, we strongly encourage everyone to bravely study on their own. After all, "search" is an irreversible trend in the future, and SEO is one of the core capabilities that all marketers should possess.

Create an entry-level SEO learning blueprint

Based on MySEOSites many years of experience as an SEO instructor and consultant, he found that the biggest bottleneck for most novices when it comes to SEO is that "the information on the Internet is too complex and lacks systematization." Therefore, many people end up paying for courses just to save the time and frustration of searching for information.

But in fact, as long as you can establish a complete learning framework, you can greatly reduce the confusion of learning. This architecture diagram we usually use in teaching not only clearly sorts out the learning context of SEO, but also corresponds to our team's daily optimization process. Each one is an indispensable skill in practice, and is the core knowledge that you should master in depth during the self-study process.

Below we will also organize the key concepts and further readings one by one to help you walk more clearly and with more direction on the road of self-study.

SEO tutorial step 1: keyword strategy research

The Importance of Keyword Strategy

Initial goals and strategies are crucial in any website optimization or marketing effort, and this is also true in the field of SEO. If the strategy deviates from the beginning, the overall optimization results will be less than expected. The foundation of SEO optimization strategy often comes from "keyword strategy", and the formulation of this strategy begins with the key step of "keyword research". Therefore, it is recommended that beginners start from this point and master the core concepts of keyword research first, which will form the basis for subsequent successful optimization.

Keyword analysis tools

The first step in researching a keyword strategy is to select the keywords you want to operate on. Many beginners may encounter the following confusion at this stage:

• • Without a clear direction, it is difficult to decide which keywords to attack
  For example: When choosing between “bread recipes” and “cookie recipes”, how do you evaluate which topic has greater market potential?
• • After selecting keywords, I don’t know which keyword has the highest exposure efficiency.
  For example: Should you choose "Tokyo travel" or "Tokyo attractions" to attract more searchers?

At this time, we need to use the "keyword analysis tool" to conduct in-depth research. Through these tools, we can obtain data such as keyword search volume, competitiveness, and search trends, so as to understand the size of the keyword market and user behavior, and further determine the direction of keyword selection. In addition, these tools can help us analyze competitors’ keyword strategies and provide more ideas and inspiration.

Keyword Type & SERP Search Results

After selecting keywords, the next step is to analyze keyword types. Keywords can be divided into three types, each of which is displayed differently in the search engine results page (SERP):

• Transactional keywords: These keywords usually show up for e-commerce sites and are designed to directly drive sales.
• Informational keywords: mainly display articles or materials, with the purpose of providing users with more background information or guidance.
• Navigational keywords: Users want to go directly to a specific website, usually a brand name or trademark.

For example: The SERPs for the keyword “headphones” are mostly shopping websites, while the SERPs for “headphone recommendations” are more likely to be information articles, which reflects that Google believes that users have different intentions when searching for these keywords. Therefore, when developing a keyword strategy, we need to first evaluate the form of the search results and choose the most appropriate page for optimization.

Keyword ranking optimization: keyword map

The final step in your keyword strategy is to create a “keyword map.” This is a planning tool that is used to sort out the keywords that different consumers need at different purchasing stages and map them to appropriate website content.

For example: In the case of selling ergonomic chairs, we can analyze consumers’ needs at each stage of their purchasing process and infer what questions they will search for. Based on this information, we can design exclusive keywords for different stages and map them to specific landing page content, thereby improving the page’s search ranking and conversion rate.

SEO Tutorial Step 2: Technical SEO

The Core of Technical SEO

Technical SEO is a very important part of SEO. It focuses on the technical architecture of the website to ensure that search engines can effectively crawl the website content and rank it smoothly. If the website's technical structure is not user-friendly, search engines will not be able to correctly parse the website's content. Even if the website's content is high-quality, its ranking may be affected. Therefore, the website's technical architecture must be search engine friendly, which is the basis for any subsequent SEO optimization work.

SEO first step: Let Google search your website

The first step in technical SEO is to make sure Google can find and crawl your website. The principle of how search engines work is that Google's crawlers will first perform a "crawl" to visit your website and read its content, and then perform an "index" to store the website's information and display it in the search results. If your website is successfully indexed, it means that it will appear in Google's search results.

There are many factors that affect Google's retrieval and indexing, such as the website's architecture, website speed, etc. To confirm whether your site has been successfully indexed by Google, you can use Google Search Console or use the Site command to check the index status of your site.

SEO important foundation "website architecture"

Website architecture is crucial to SEO. You can compare website architecture to the location of a restaurant. If the restaurant is located in a cramped and hard-to-reach place, customers will stay away even if the food is delicious. The same is true for SEO. If the website structure is not conducive to search engine crawlers, even the best content will find it difficult to achieve good search rankings.

When designing an SEO-friendly website architecture, we need to optimize the following technical SEO items:

Technical SEO Summary

Understanding the website architecture and performing correct technical optimization are the basis for ensuring that the website can be successfully crawled by search engines and displayed in search results. If the website's technical architecture is not user-friendly, even if the subsequent SEO strategy is good, it will still not achieve the desired results. Therefore, technical SEO is the most basic and essential step in any SEO work.

SEO Tutorial Step 3: Algorithms and Ranking Factors

In the previous SEO tutorial, we have covered keyword strategies and technical SEO of websites. Next, we will focus on how to improve the SEO ranking of websites through Google's algorithm. Google uses dozens or even hundreds of "signals" to analyze the quality and relevance of websites. These signals are called "Ranking Factors" or "Ranking Signals."

The SEO algorithm is very complex, so when learning, we can divide these factors into two categories: "quality signals" and "relevance signals". The following will introduce these two types of signals in more detail.

SEO ranking factors: Quality signals

Quality signals are key factors that Google uses to determine whether a website is a high-quality website. They mainly focus on the "importance" and "user experience" of the website, which are the core factors that affect website rankings.

➊ Website importance: website weight, backlinks

Domain Authority (DA) or backlinks is a key factor in SEO. Google uses backlinks to determine the credibility and importance of a website. The more high-quality backlinks you have, the higher your website's authority will be and the better your ranking will be.

In addition, "brand power" will also affect the weight of the website. Long-term brand management, cooperation with public relations media, and strategic backlink construction can all help improve the weight of the website.

suggestion:

• ✓ Increase high-quality backlinks.
• ✓ Cooperate with industry websites to exchange content or link to each other.

➋ Evaluate user experience: website speed, security, mobile experience

Google attaches great importance to the user experience of the website, which is an important factor affecting SEO ranking. Google has a "Core Web Vitals" to evaluate the performance quality of a website, including its loading speed, interactivity, and visual stability.

In addition, the website's HTTPS security, mobile version experience, and avoiding pop-up ads will also directly affect SEO rankings.

suggestion:

• ✓ Use HTTPS to keep your website secure.
• ✓ Optimize website loading speed and mobile version display effect.
• ✓ Avoid too many pop-up ads and interruptions.

SEO ranking factors: relevance signals

Relevance signals are signals that Google uses to determine the relevance of a website to specific keywords. These signals mainly come from elements such as website content and web page titles. Google uses these elements to determine whether a web page is relevant to a particular search query.

➊ SEO website content

Google places great emphasis on the quality of website content and considers it a key ranking factor. Website content should be professional, practical and helpful to users, rather than just stuffing keywords for SEO ranking.

suggestion:

• ✓ Write valuable original content and avoid duplication of content.
• ✓ Articles should provide solutions or useful information for the target audience.

➋ SEO article writing

The process of writing SEO articles can be divided into three stages:

• Preliminary research: determine article objectives, keyword setting, and data collection.
• Mid-term writing: set article title, structure and keyword density.
• Post-optimization: track the effectiveness of the article, make adjustments and optimizations.

suggestion:

• ✓ Keep your keyword usage natural and avoid over-stuffing.
• ✓ Create an attractive title and structure to keep your article easy to read.

SEO article structure and practical exercises

When writing SEO articles, structure is very important, and a good structure helps improve SEO performance. With the right title, appropriate paragraphs and keyword density, your article can get higher exposure in search engines.

• Title and Meta Description: The title should clearly contain keywords and attract clicks. Meta description should be short and attractive and contain your target keywords.
• Paragraphs and headings: Divide the article into paragraphs reasonably and use headings (H1, H2, H3) to organize the content to improve readability and search engine understanding.

These steps and concepts will help you improve your website’s SEO ranking and attract more valuable traffic. If you want to learn more about how to optimize your website content, you are welcome to read more detailed SEO articles and practical exercises.

SEO Tutorial Step 4: SEO Software and Data Analysis

Why should you learn SEO data analysis?

SEO is a field that requires a lot of trial and error. When learning SEO, data observation and analysis are very critical. Data not only provides a basis for us to plan keyword strategies, but also plays an important role in performance monitoring, ranking tracking, website health diagnosis and other aspects. For SEO novices, understanding and mastering the use of data can greatly improve the efficiency of learning and implementing SEO, allowing us to discover problems and adjust strategies more quickly.

SEO software tool list

After understanding the importance of data analysis, how do you start observing this data? In practice, we can rely on a variety of SEO tools to assist with data analysis and website optimization. There are many SEO software on the market, each with different functions. Common ones include "Google Official Tools", "Keyword Planning Tools", "Website Analysis Tools", "Speed Detection Tools", etc. Here is a list of some commonly used SEO software tools:

➊ Google Official SEO Tools

The free tools provided by Google are indispensable for SEO. These tools not only help us track website traffic and performance, but also assist us in checking technical issues to improve SEO results.

• Google Search Console: Used to analyze the SEO performance of a website and view natural search performance and technical SEO status.
• Google Analytics: Analyze website traffic sources, user behavior and interactions.

➋ Keyword Planner

When planning your SEO keyword strategy, keyword analysis tools are indispensable. These tools can help us analyze keyword search volume, competition, and search trends, and monitor rankings, giving us a clearer direction for keyword attack.

Common keyword tools include:

• Ahrefs: It has powerful functions. In addition to keyword tracking, it also has many other functions such as website health check.
• Ubersuggest: Provides complete keyword analysis at a relatively low price, and a free version is available.

• SimilarWeb: Analyze the traffic of competitor websites. It is easy to operate and the data is accurate.
• Moz: Focuses on backlink analysis and also provides keyword analysis, competitor analysis and other functions.

➍ Website speed test tool

• PageSpeed Insights: A website speed detection tool officially provided by Google.
• Web Page Test: Provides a detailed website speed test report.

These tools can help you gain insight into the health of your website and make improvements based on the data, ultimately improving your website’s SEO ranking and user experience.

In advanced SEO learning, there are some myths and common misunderstandings that need to be clarified, and mastering some key concepts is the key to successful optimization. Here are a few key points to help you understand advanced SEO.

SEO Myths Busted

• 1. Do bounce rate and dwell time affect SEO?
  This question is very common, but in fact, the impact of bounce rate and dwell time on SEO is not as direct as many people think. Although high bounce rates and low dwell time may indicate a poor website experience, Google does not rank websites based solely on these data. The core of SEO is still the quality of website content, user experience and website structure.
• 2. Does Facebook community management affect SEO?
  Social media activity itself does not directly affect a website’s ranking in Google, as Google does not currently use social media data directly for ranking. However, social media activities do help to attract traffic and indirectly increase the website's exposure and organic traffic, which may affect the website's SEO performance.

E-commerce SEO optimization

On e-commerce websites, product search volume and conversion rate are the core of SEO success. However, many large e-commerce websites such as Amazon, eBay, etc. often dominate the homepage of search results. For small and medium-sized e-commerce websites, the success of SEO lies in content optimization, especially the SEO of product descriptions, titles and images.

Here are some practical SEO optimization suggestions:

• ✓ Product page optimization: For each product page, create high-quality product descriptions and images, and use keywords to enhance SEO effects.
• ✓ Internal link building: Reasonable internal linking of internal pages will help improve the SEO value of website structure and content.
• ✓ Use long-tail keywords: Highly competitive short-tail keywords (such as “headphones”) are difficult to rank for, so long-tail keywords (such as “high-quality bluetooth headphones”) are a better choice.

It is recommended that beginners be patient when self-studying. It takes at least half a year to a year to deeply understand the basics and advanced concepts of SEO. Although there are many resources available for self-study nowadays, the key to ultimately mastering SEO lies in whether you can effectively organize your learning materials and develop the habit of reading SEO news and practicing every day.

FAQ about SEO health check for beginners

When you start learning and practicing SEO, it is very important to check the SEO status of your website regularly. Here are some common questions and suggestions to help you check and optimize your website.

Keyword research related

• Q1: How to check whether the website’s keyword strategy is correct?
  A: Make sure each article has a clear "search intent" and "target keywords", and naturally distribute the keywords in the page title, content, and internal links. You can use Google Search Console to observe the actual search keywords that each page brings in to see if they are consistent with your expectations. If keyword traffic is not ideal, you may need to readjust your strategy or optimize your content.
• Q2: Is the website content layout competitive?
  A: Compare your content with the websites ranked on the first page of search results, check the depth of the content, whether it covers the issues that users care about most, and whether the page layout and paragraph structure are conducive to user reading. Having quality content structure and design will help you improve your competitiveness.

【Technical SEO Health Check Related】

• Q3: Will using JavaScript to generate content on a website affect SEO?
  A: Maybe. Search engine crawlers primarily read HTML and CSS code, and may have limited recognition of content generated by JavaScript. If the website content relies on JavaScript generation, search engines may not be able to crawl these contents, affecting SEO results. It's best to keep the important content directly in the HTML.
• Q4: Will incorrect redirection settings affect SEO?
  A: Yes, incorrect redirection settings will affect website SEO. Incorrect redirection (such as using 302 temporary redirection or duplicate redirection links) may reduce search engine crawling efficiency and affect rankings. A 301 permanent redirect should be used to redirect the page correctly.
• Q5: How to submit website Sitemap to Google?
  A: The easiest way is to submit a Sitemap manually through Google Search Console. You can also use the Search Console API or add the Sitemap path to your website's robots.txt file to achieve automatic submission.
• Q6: How to set robots.txt and meta robots correctly?
  A: Robots.txt should avoid blocking any important pages. Generally speaking, we do not recommend using robots.txt to prevent search engines from crawling website content. You can use the meta robots tag to set whether a page should be indexed (noindex) or followed (nofollow).
• Q7: How to check whether the website performance is good? Is there a speed issue?
  A: Use tools like Google PageSpeed Insights or WebPageTest to test your website performance and check how fast your web pages load. These tools will point out files that are slow to load and provide optimization suggestions to help improve your site speed.
• Q8: How to check the user experience of the website? Is the mobile experience good?
  A: Check the user experience of mobile and desktop versions through the "Site Experience Core Indicators" in Google Search Console. These metrics will tell you if there are any pages that need improvement to ensure that the site has a good experience on all devices.

SEO ranking factors related

• Q9: How do I check my backlink status?
  A: Use tools like Google Search Console or Ahrefs to check the quantity and quality of your website’s backlinks. Check the websites where your backlinks are coming from and regularly review which pages are being shared and linked to, and also watch out for lost backlinks.
• Q10: How to set H1 and H2 correctly?
  A: Each page should have only one H1 as the main title, and other paragraphs should use H2 and H3 as subheadings to help Google understand the structure and content of the page.
• Q11: How to set the Title and Description correctly?
  A: Each page must have a unique Title and Description.
  Title: Should contain target keywords and be within 60 words.
  Description: Describe the main content of the page. There is no need to deliberately insert keywords. Keep it clear and concise. The word count should be controlled within 160 words.
• Q12: How to create content that takes into account SEO effectiveness and is helpful to users?
  A: First clarify the search intent behind the keywords, then write content that can solve the user's problem. The content should be in-depth and provide practical information and data support, and incorporate unique perspectives and experiences to add value to your content. This will not only improve your SEO rankings, but also increase user satisfaction.
