Why is on-page SEO important?

On-page SEO is important because it helps search engines understand the content of your website, as well as determine if that content is relevant to a user’s search query.

As search engines evolve, Google focuses more and more on relevancy and semantics in search engine results pages (SERPs).

Google, with its countless complex algorithms, has now become much smarter at:

  • Understand what users are looking for when they type a query.
  • Provide search results that meet the user’s search intent

Adapting to this development is essential. Make sure your website and content are well optimized according to Google’s guidelines.

Optimizing Onpage SEO to increase rankings and user experience

Onpage SEO helps increase rankings and user experience

Basic Onpage SEO optimization standards

Use Target Keyword in the first 100 words

This is an Onpage SEO tactic that makes all the difference. You need to optimize for the main keyword that appears once in the first 100-150 words of the article.

Why is it important?

Google prioritizes terms that show up early on your site. This is why you want to insert your main keyword somewhere in the first 100 words. This is one of the Onpage SEO factors that help Google understand your content.

URL Optimization

URL structure is a factor that greatly affects Onpage SEO. The shorter the URL, the easier it is for the website to get to the top .

Please optimize the URL according to the following criteria::

  • Short URL, related to the article content
  • The URL contains the main keyword (the keyword with the highest search volume)

Optimizing Title

Title tags are the most important on-page SEO factor . That’s because the title tag gives search engines an overview of the web page’s content. The closer the keyword is to the top of the title tag, the more powerful it is with search engines .

Keywords don’t have to be at the beginning of the title. Because you can’t always do that. But in the title tag, the earlier the keyword appears, the better.

Optimize Meta Description

Meta Description is the short description (about 156 characters) that appears below the title in search results. It lets the user know what the website content is about and stimulates the user to click.

Instead of trying to cram keywords into the Meta Description, you should optimize CTR to attract more visitors to your website. From there, improve keyword rankings effectively.

Heading 1 

The H1 tag is like a small title tag of the web page. In fact, Google has stated that using the H1 tag helps Google understand the structure of the web page.

Factors to pay attention to when optimizing Heading 1:

  • H1 contains related keywords (the keyword with the 3rd search volume)
  • H1 content covers the entire article
  • There should be only 1 H1 tag. If you use more it may confuse Google
  • H1 should be different from title and URL (LSI keyword).

Heading 2-3

Besides optimizing Heading 1, you should pay attention to optimizing Heading 2,3 to help Google better understand your website.

Some notes to optimize Heading 2.3 effectively:

  • Be brief and express exactly what the paragraph below is referring to.
  • Implement as many Sub-headings as possible.
  • Heading 2.3 avoids keyword stuffing, using related keywords or semantic keywords.
  • Heading 2,3 affects a lot of SEO, and heading 4-6 does not affect much.

TOC optimization (table of contents)

You should optimize the TOC really differently to improve the user experience . Article TOC is like a book’s table of contents.

When you hold a book, first read the table of contents to quickly find the content you want. TOC helps navigate readers to the right content they are looking for quickly.

In addition, the Google Hummingbird and Google Rankbrain algorithms are extremely fond of TOC. That’s why TOC optimization is absolutely beneficial for SEO.

Strong Keyword (bold keyword)

You should bold the main keywords in the article to mark for Google to understand that it is the important keyword of the article. The main keyword density is from 1-3% evenly distributed throughout the article .

In addition, you should insert secondary keywords, related keywords throughout the article to increase the relevance, forming a unified content.

Article length

Article length is a factor that helps Google evaluate whether your article is in-depth and brings a lot of value to users. According to research, the article should be 1890 words or more in length, it is called SEO standard.

Jonah Berger proves that articles over 2000 words have more in-depth content, stay with users longer, and tend to be shared more.

Density keyword

Keyword density is the number of times a keyword appears in the article content. Google may negate the benefit of using the same keyword more than once. But experienced SEO experts say it really helps.

Imagine that your page has a special keyword, but its frequency appears only once. Surely Google will doubt whether your article is talking about that topic.

However, if that keyword appears more than once, repeated throughout the article, then Google will make sure your content is related to that keyword.

You can use the same keyword more than once, but that doesn’t mean you stuff it , making the article lose its naturalness. Sometimes even get penalized by Google for over-optimization.

Semantic Keyword

Semantic Keyword is a semantic keyword that helps Google better understand the context and topic of the article, creating depth of content.

Semantic keywords are an important part of Onpage SEO strategy . Keywords that are semantically related to the original keyword help search engines have a more in-depth look at the topic of the article as well as the context in which it is mentioned. This is a Google website ranking factor that you need to pay attention to.

Optimize images

Doing SEO is not only optimizing content but also optimizing images. Poor quality and unoptimized images will directly affect your website’s ranking on Google.

Notes when optimizing images for SEO standards:

  • Name images unsigned and separated by dashes –
  • Optimize SEO standard tags for images
  • Fill in the description information such as author, description, title, … in the image
  • Using Alt tag, insert Semantic Keyword or SEO Keyword into Alt tag. The image has a full description will help the image to top Google Image easily.
  • Should insert the exact keyword in the first image. In addition, limit inserting too many keywords into the image.

Readability Optimization

Readability is an indicator of the readability and readability of the article content.

Readability affects 4 main factors:

  • Bounce Rate
  • Dwell on time
  • Conversion Rate
  • Featured Snippets.

When you optimize Readability, users will easily crawl and stay longer to read that article . This will reduce bounce rate and effectively increase conversion rate.

Content unique
