In addition, writing standard SEO Onpage articles from the beginning will help you control the content, better quality, and easily Onpage later.

Basically, standard SEO articles need to meet SEO criteria about Title, Meta Description, H1, H2, URL… Those criteria will be guided and explained in detail in the checklist of 21 factors affecting SEO Onpage below This.

When to build Onpage SEO?

Building Onpage SEO is very important, so you must have a priority when doing this work. Especially when its implementation is completely free. Specifically:

You should set up Onpage SEO factors right from the moment you just built the website. The setting elements can be website structure, Https, sitemap, etc.

Jobs that require you to perform regularly such as: writing new SEO content, auditing content, optimizing page loading speed, etc.

You still have to perform Onpage SEO work even though you are ranked first on Google to maintain long-term rankings.

Who should do Onpage SEO?

This job is not only for SEO people but for everyone who wants to improve website rankings. You can be a blogger, do affiliate, start a product or service, etc. You all need to do Onpage SEO.

Whoever you are, if you want to improve your website’s rankings, you must perform Onpage SEO.

11 Onpage standards are prioritized by Google

In this chapter 2, I will reveal to you the top 11 Onpage SEO standards being evaluated by Google. Mastering and effectively applying these 11 standards will help your website be “”favored”” by Google, creating an opportunity to quickly rank your website and occupy high positions in the search results.

1/ Optimizing URLs in Onpage SEO

URL is one of the biggest influences on Onpage SEO.

Remember, optimize Onpage SEO so that the shorter your URL, the higher the ability to get to the top.

Put your focus keyword (highest search volume) in the URL.

Optimizing both URLs in Onpage SEO to achieve the highest-ranking

So, a good SEO Onpage standard URL needs the following 3 factors:

Contains the main SEO keyword (with the most search volume)

Keep it short, but get the whole idea across (top 1 URLs usually have an average of 59 words).

Related to the article content

Note: It is recommended to combine multiple keywords with the same search intent (Search Intent) into the same URL for SEO a bunch of keywords at once.

2/ Optimize Title

If the Title is well done and attractive enough, they will click on the article in the proper focus of the search. From the perspective of search engines like Google, optimizing the Title will help the engine crawl faster and more accurately, thereby understanding the article’s content.

Speaking of here, you probably realize the importance of Title in SEO, right!

In the past, you could put a few keywords in the Title and increase your chances of ranking. However, the giant Google has grasped this trick and reduced the importance of inserting the correct keyword in the Title.

The Title is well made and attractive enough; the proper focus of the search will attract users to click.

Some notes when optimizing Title:

Each Title is separated by | or –

Should contain keywords that need SEO Onpage with the 2nd highest search volume (The keyword with the highest search volume will be in the URL)

Must not contain precisely 100% of the keywords already in the URL

For example, if the URL is already service-SEO, the Title should not be just “”seo service”” but should be “professional seo service.””

PuttSEO SEO keywords in the top position of Title help increase CTR rate & rankings.

Also should not be the same as Heading 1. You need to put the Title with related keywords and the same keywords.

Include as many keywords as possible but be natural.

Note for the homepage:

In case you do SEO Onpage for the homepage (homepage), the homepage needs to:

Brand name in Title.

The Title must represent the content of the entire domain and clearly support the parent directories.

If your website is about e-commerce and provides air conditioners and washing machines, the homepage’s title must cover all the content you mention so that Google can understand and crawl all the sub-contents faster.

3/ Heading 1 in Onpage SEO

Google is a fan of relevancy. So, when optimizing Onpage SEO with the Heading 1 tag, try to be as diverse, relevant and user-oriented as possible.

Contains important relevant SEO keywords (with the 3rd most search volume)

Include article content

There is only 1 Heading 1 tag only. If you have many Heading 1 tags, it will confuse Google and affect the ranking of the article.

Must be different from Title and URL and should be a different LSI keyword.

4/ Heading 2-3 in Onpage SEO

In addition to optimizing Heading 1, you need to focus on optimizing Heading 2-3 to help Google better understand the content of your website.

Some notes when optimizing Heading 2-3:

-Briefly, show the content of the upcoming paragraph you are talking about

-Implement as many Sub-Headings as possible

-Heading contains some related keywords or Semantic Keywords. Don’t be too stuffed with keywords; make it short and show the content of the paragraph

-Headings 2-3 strongly affect SEO and 4-6 do not affect much

For example, a content article about back pain on the Wikipedia page is clearly divided into: Classification, symptoms, causes, treatment …, referring to any problem, mention that problem.

5/ TOC (Table of Content)

TOC design really makes a difference:

Good optimization of user experience

When you buy a book, sometimes you don’t read the whole book, but look at the table of contents, the first title to quickly find the information you want. TOC plays a role of navigation, helping readers get to the section they are looking for.

Google’s Hummingbird & Rankbrain Algorithm loves TOC

Alternatively, if you use WordPress, you can use the TOC Plus Plugin.

Table of Content is an essential part of user experience

6/ Bold the main keyword in the article

The main SEO keywords must be bold in the article.

The main keyword density is 1-3%, evenly distributed in the introduction, H1, H2, body, and conclusion. In addition, spread secondary keywords / related words/synonyms throughout to increase the relevance of ideas, creating a unified subject for the article.

Remember that no matter what tricks you do in the web SEO process, you need to prioritize the natural, don’t force it, but cram all the keywords into the article. The best web SEO is to always think of the user.

7/Length of article

Post length is one of Google’s fastest and easiest ways to gauge if your article is in-depth and user-oriented.

Some figures show that 1890 words will be the best number for the Length of an SEO standard article.

Why 1890 words?

Jonah Berger proves that articles over 2000 words tend to be shared the most. Because there is more in-depth content, users’ time staying on the web and reading articles will also be longer.

Of course, it cannot be said that a 400-word article is unlikely to be higher than a 190-word article. Articles with more than 1890 words will have a slight advantage over short articles.

8/ Semantic Keyword

Semantic Keywords are like creating depth for content. Unlike LSI (Latent Semantic Indexing) keywords, Semantic Keywords are keywords that help users and Google understand the context/topic of the article better.

I mentioned the concept and how to optimize Semantic Content in the article What is Entity earlier; please take a closer look!

Usually, you will start researching 10-20 Semantic Keywords and then insert them into the article that needs Onpage SEO.

For example, you SEO keyword Steve Jobs. Semantic Keyword words you can insert include:

Steve Jobs

Apple founder

Macintosh, …

Semantic Keywords will help users and Google better understand the context when it comes to Steve Jobs. You can add CEO because he is the founder of Apple.

And the keyword “Steve Jobs” is also related to Apple, Pixar, Walt Disney… Even if you don’t have SEO intent for the keyword “Pixar” or “Walt Disney”, the act of mentioning these keywords will help Google draw the result vector. Join Entities between them.

Do not think that optimizing SEO articles about Steve Jobs keyword, Steve Jobs keyword density is 5%, so you must bold Steve Jobs keyword and stuff this keyword into the article …

This is an old-fashioned way!! Instead, like what I share, optimize for Semantic Keywords.

Semantic Keywords will help users and Google better understand the context of keywords.

9/ Pictures

Not only optimizing the keywords and content of the article, but you also need to pay attention to optimizing the images posted on your website effectively by:

Names of images must be unsigned and marked with – between words.

Optimize SEO tags for images.

The meta sections in the image must be filled in fully including (Title, Subtitle, Author, Meta Description …) or at least name the image before uploading.

In addition, you can optimize more deeply by applying image SEO to the top of the search.

Because Googlebot does not recognize images, it can only read letters or characters. So, adding text to the image will help Google recognize it faster, easier and more effectively.


Use alt text tags (insert Semantic Keywords or SEO Keywords). The alt tags with full description will help the image to top Google Image.

The first image should contain exact SEO keywords but also avoid inserting multiple keywords in the image.

10/ Optimize Meta Description

The Meta Description tag is the short description (under 156 characters) displayed in the results. Search results, letting users know what your site is about before clicking.

Good Meta Description will attract more readers

At the present time, inserting keywords into the Meta Description is not of much interest because it is no longer as effective as it used to be.

So instead of trying to stuff keywords in this description, try to optimize for CTR, making traffic to your website higher. From there, indirectly improve keyword rankings.

11/ Optimize Readability

Optimizing Readability with Yoast SEO

First need to optimize Readability

So what is Readability SEO Onpage?

Readability is the ability of readers to crawl your article.

This is extremely important because it affects 4 factors:

Bounce Rate (bounce rate)

Dwell on time (reading time)

Conversion Rate (conversion rate)

Featured Snippets. Yes! One of the most important and little-known factors is that you greatly increase your chances of getting to the top 0 (featured snippet) position when you optimize Readability properly.

Why does it affect the above 4 factors?

Simply, when you optimize Readability, you will make it easier for users to collect information. That leads to them staying read longer.

Combined with internal linking, Readability will help reduce bounce rates and increase conversion rates a lot.


Advanced Onpage Standards

Advanced Onpage standards are often easy to ignore because many people really don’t understand what they are and how to implement them. In this chapter, I will continue to bring you 8 Onpage SEO standards, helping you to differentiate your Onpage, increase your competitive advantage over other competitors in the market.

12/ Content unique, in-depth and responsive Search Intent

seo on page là gì, Cơ sở dữ liệu trực tuyến

Unique content here is not simply content that does not contain duplicate content, but it also means that the content must bring new and more unique things, not simply rewrite what is already there.

You can do your research and read more documents to develop content that no one else has written. This will create uniqueness for your article; users will enjoy and appreciate you more.

Besides, the content must also meet the search intent of the customer. I will talk a little bit about search intent so you can understand better.

Search intent is understood as the intention and intent of the user when they search on SERPs like Google. Identifying the right search intent will help your website be found more, thereby effectively increasing traffic to the website.

Identifying the right search intent will help your website get found more

Regarding intent types, there are currently about 9 most popular types of intents. To know more about these 9 intent types as well as answer questions related to search intent, you can refer to my following article: What is Search Intent? Latest Content SEO Improvement Methods 2021

For example, when I search for the keyword “evening dresses”, I see a list that returns at the top of the page with only images. From here, I can determine that the user wants to see the main visual images with this keyword. As such, I will focus on providing more images in the articles when implementing.

Similarly, you can base on customer intent in search results to determine the direction of your content implementation that best meets user requirements. Therefore, a standard content is not a very long and a lot of content, but content that is optimized to follow the customer’s intent.

Customer Intents are Visuals

13/ Featured Snippets

Featured Snippets help attract readers right from the search page.

First, you need to know what are the two most important factors affecting Featured Snippet placement:

#1. Reputable website in that set of keywords

Simply put, for a specific range of keywords, web position is directly proportional to Google’s trust in the website. You can see below the chart showing the percentage of Featured Snippets appearing at each top.

Featured Snippets appear more on top sites.

Optimize Featured Snippet with 5 extremely simple steps

#2. Verified information

The accuracy of information on the website is the second factor that directly affects the Featured Snippet position.

Google evaluates the accuracy of a website by comparing the information text on the web with the data it collects at major sites worldwide. If this information is similar/synonymous with data from major news sites, Google will know that the information is accurate and correct.

But… how does Google know it’s the information users need to show up in the top positions?

That’s when you need to make it possible for Google to understand that it is the user’s information and that Google should take that text.

And all of this is done through Readability.

#3 Tip: Optimize Readability

Use Yoast SEO’s support to optimize Readability.

Ah, this is simple, if you have Yoast SEO installed then you just need Turn on the Readability section.

Then follow the Yoast SEO guide and that’s it! You just need to optimize it for ok (Orange) and not Good (green).

In addition, you can use features such as Blockquotes, Table, Bullet, Point … and insert videos, design more vivid images, increase user interaction and reduce the bounce rate.

Here are some video insertion standards:

Width at 600 pixels

Videos and images are centered

14/ Internal Link and Outbound Link

A fully optimized article needs a combination of Internal Link and Outbound Link.

Internal Link makes it easier for users to navigate, to help Google collect data. In addition, it also transfers power between posts. As well as giving users more valuable information, thereby improving the SEO ranking of the website.

On the Outbound Link side, you’ll also want your site to Link to other reputable sites. Outbound links will help Google understand your website’s topic better and help you build relationships with other websites.

More importantly, External Links have a positive impact on SEO. Specifically, it helps you increase your trust (Google trust) many times.

15/ Blockquote

If you still don’t understand Blockquote well, I will explain to you before you know what Blockquote is. The Blockquote is known as a tag used to attach citations when you want to get something from another source in HTML to add to your article.

Usually, Blockquote is used to mark a famous saying, cite facts, truths, or emphasize the article’s content.

The text content in the Blockquote tag will automatically indent, separate from the rest of the content in the article. Below will be an illustration for Blockquote:

This is how the Blockquote is displayed in the article.

What are the benefits of Blockquote for Onpage SEO:

– Blockquote shows respect for your copyrights to content from other websites

– Support you to rank top Google better when SEO Onpage

16/ Advanced image optimization

As for images, in the previous chapter, I showed you basic optimizations. Continuing in this chapter, I will suggest you some advanced ways to optimize your images professionally and effectively.

First, I will mention some benefits when you optimize images:

Images can be Featured & top Google Image

Support to promote SEO

Playable brand and local brand

17/ Advanced title optimization

Regarding title optimization, I have presented some basic elements above. Here, I will continue to share some real tips to improve your title optimization, helping you achieve more effective Onpage performance.

First, about the title standard, you should note the following two points:

30 lowercase characters < title SEO < 63 lowercase characters

200 pixels uppercase characters < title SEO < 550 pixels uppercase characters

Second, note the 3 advanced title optimization criteria as follows:

Put the keyword at the top left of the Title

Competitor analysis, inclusive optimization

Add variant keywords to Title

Remember to put the keyword right next to the top left!

18/Content GAP

First, I will explain the concept of Content Gap if you still don’t know what this is! Content Gap is understood as a process of reviewing and evaluating Content, identifying the gaps in your Content compared to other competitors’ Content on the same topic. Through that, you can draw experiences from which you can improve your Content, increase your competitive advantage.

Benefits of implementing content Gap:

– Help you fix your content errors, improve content quality effectively

– Help you discover potential topics, attract more users

Improve the keyword research process to be more efficient and accurate.

19/ Optimize CTR with Structured Data (Schema Markup)

CTR (Click-Through Rate) is also known as the click-through rate. To be clear, the CTR metric measures the ratio of an ad’s clicks to its impressions.

In SEO, CTR will tell you how many people saw your link in total and how many people clicked on the page. The higher the click-through rate, the more your website has customers’ trust, the more customers will find you.

To optimize CTR, in addition to the standards of Title, Meta Description, etc., the use of structured data is also essential.

Structured data (Schema Markup) is the element to create rich and diverse interactive Content. Structured data helps users have a visual experience that increases click-through rates for the website.

20/ Anchor text

Anchor Text is a small factor, but it helps you better SEO Onpage. Anchor Text is the text where clicking will lead you to a hyperlink.

This piece of text helps the reader understand what the main content of the linked page is. Therefore, you must ensure that the Anchor Text accurately and fully represents the Content of the affiliate link.

Anchor Text is a small but indispensable element when SEO Onpage

Some tips to optimize Anchor Text:

– Do not write too general anchor text such as: click here, here, … but describe the linked website more specifically.

– Limit repeated use of an anchor text. Write newer Anchor Text assets.

Therefore, optimize your website by using more videos. It can be videos from your own Youtube channel, valuable videos for users, etc.

You can insert videos directly on your blog posts so that readers have more choice of format (read or watch) when referencing knowledge.

The trend of watching videos is increasing.

The comment section on the website has a pretty important meaning, bringing benefits to the website. This is also a factor to help you SEO Onpage more effectively. Some highlights from the comments can be mentioned as:

– Increase customer and business interaction: Customers can leave their questions and businesses can answer them thoroughly.

– Create credibility and professionalism for the business: Transparent comments from customers, dedicated answers of businesses are factors that increase the credibility of the business.

Customer retention: Customers will often spend time looking at comments, mostly they want to find answers for themselves about a certain question or want to know more precisely about the business’s reputation. You can also take advantage of this to better meet their requirements.

23/ Favicon

Favicon is an icon of a website, maybe a website logo. I will put an illustration below for you to quickly visualize. Specifically, it is a small icon located in the left corner of the tab of the website. Through, Favicon users can identify the brand.
