On-page Optimization: How important is it for SEO?
From experience, On-Page optimization significantly benefits SEO.
It helps web pages that previously never appeared in search results to debut on pages 2-3, and it helps web pages that used to be in the lower half of the first page to soar up to the top 3 positions.

Without On-Page optimization, no matter how much you promote the webpage or create backlinks, it will be difficult to achieve good SEO results.
The benefits of On-page SEO from the perspective of ‘people’
People search on Google to find ‘answers’.
Good on-page SEO will help users find answers more quickly, starting from naming the webpage or article (SEO Title) to providing a webpage description (Meta Description, the description under the link on the search page). This will let users know if that webpage “might” have the answer they are looking for — indicating relevance.
As for the content of the webpage, such as text, images, videos, etc., it is like the answers that the webpage provides to people. Whether the answers are what they are looking for or how much value the answers provide to them depends on the ‘quality’ of the content.
On-page SEO from the perspective of Search Algorithm operations
Google prioritizes relevance and quality to select web pages that best or most satisfactorily answer people’s questions.
Optimizing a webpage for relevance, whether by using keywords that match what people are searching for in various places on the page, in the URL link, in the snippet on the search page (such as the website name, website description, and links that appear on the search page), or in other components that search bots will easily find and understand.

Additionally, it includes the quality and format of the content presented and the user-friendly design of the web pages, which also affect user satisfaction. The search bot interprets various indicators such as the time spent on a page, the number of pages visited within the same web domain (session), etc. (returning to the benefit for the user).
7 Basic On-Page SEO Techniques
1. One webpage, one topic
One of the On Page SEO techniques that significantly impacts rankings is designing content as “one webpage, one topic.”
One webpage, one topic means designing each webpage’s content to have only one main topic and then presenting all the related subtopics comprehensively.
I would like to give an example of designing article content and Facebook image sizes that have consistently ranked number one on the first page for a long time.
Main topic
- Facebook image size
Subtopic
- Facebook mobile photo size
Facebook desktop image size
Facebook cover photo size
Facebook profile picture size
So why does one webpage, one topic, benefit SEO?
Presenting with a main topic and then compiling related subtopics in a detailed and comprehensive manner on a webpage results in readers spending more time on the page. This signals to search engines that the content is of high quality and can attract readers.
The technique that keeps people on a webpage longer is consolidating related content on a single webpage. This aligns with research findings from abroad [as shown in the image below], which indicate that the more words or topics an article has, the higher the chances of achieving a good ranking.

2. Search intent
Search intent is what people looking for information want; it is the answer people seek when searching for information on a Search Engine.
Why is search intent important? Because when we align our content with what people want, it will keep them on the webpage longer. Conversely, when people start reading the content and find that it doesn’t meet their expectations, they will leave the webpage immediately, which is not good for SEO.
3. Meta Tag
Meta Tags are messages that indicate what this webpage is about. They help Search Engines understand the topics or content of the webpage.
In addition, it also helps manage indexing. We can use Meta Tags to determine whether this webpage will appear on search engines or not.
Metatags have a significant impact on SEO because they are the first text that users see on the Search Engine. If written according to SEO principles, they create a First Impression that attracts more people to visit the website.
4. URL
A URL is a string that represents the “address on the internet” of a webpage. Here are some techniques for optimizing URLs for SEO.
- There are keywords that need to rank mixed in the URL.
- Choose concise letters that reflect what the webpage is about. For example, if the article is about On Page SEO, set the URL as https://contentshifu.com/en/pillar/seo-on-page.
- Avoid using dynamic URLs that have a chaotic mix of letters and numbers, as people may lose trust when they see such URLs and may not visit the webpage.
5. Heading Tag
Heading Tag (H) is an HTML Tag used as the “article title.” The Heading Tag comes in various sizes, from H1 to H6, with each size having different characteristics.
Search engines give more importance to text that is in Heading Tags than to regular text. Therefore, Heading Tags indicate to search engines what the webpage is about and what topics it covers.
In addition, it helps organize the content on the webpage to make it easier to read, resulting in the webpage viewers understanding the content quickly and easily.
On-page SEO techniques for Heading Tags
- H1 is very important; it should be on every webpage.
- H1 should be used as the title of the article and there should be only one H1 to help the Search Engine understand what this webpage is about.
- There are keywords distributed across various main and subtopics.
6. Image
Nowadays, beautiful illustrations are indispensable for websites because they help the content flow smoothly. Moreover, some images help readers understand the content better than lengthy descriptions.
Why do images contribute to SEO? Imagine reading content that is just long paragraphs of text. It would require more effort to read and lack the enjoyment of visual appeal. This might cause viewers to leave the webpage prematurely, which is not good for SEO.
Techniques for optimizing images that are good for SEO
- Every image should have Alt Text (Alt Text is a description of the image embedded in the HTML Code that helps Search Engines understand what the image is about). The characters in the Alt Text should include keywords.
- You should not use duplicate Alt Text, but instead write a description for each image accurately.
- Adjust the image size to fit the display device, meaning that images displayed on mobile should be smaller than those displayed on desktop. Using images that are too large may slow down the loading speed of the webpage content more than it should.
7. Page Speed
Page Speed is the speed at which a webpage’s content is displayed, which greatly affects SEO. If the content is displayed slowly to the point of frustrating users, there is a high chance they will leave our website immediately and visit another website instead.
The incident caused the bounce rate to increase, sending a signal to search engines that our webpage is not engaging enough for viewers, making it difficult to achieve good SEO results.
Summary
On-page SEO is the optimization of content on our web pages or website itself to be suitable for both website users and the Search Algorithm, indicating what the webpage is about and what it is discussing.
The benefit of On-page SEO is that optimized web pages will yield better SEO results. The detailed methods have been thoroughly presented in the article. I believe that if everyone implements them, your website will definitely see improved SEO results.
