In this article, we will expound 13 best on-page SEO checkups that are sure enough to enhance page experience for search engines and users too. In a long run, it will also heighten traffic and earning.


If you look at SEO practice carefully, you will notice that off-page activities are more and less the same for a long time. Things like link building, keyword research are the same as before, but on-page SEO keeps increasing from time to time.

On-page SEO activities only increase due to the addition of AI and machine learning features to search engines. 

Like schema data, it was not a part of on-page SEO until a few years ago, but now it is a big factor in itself.

13 Best on-page SEO checkups 2021

Let us jump onto our main topic, which is the best on-page SEO practices in 2021:

1. Crawling Checkup

Search engine bots visit the website, which is called crawling. By this process, the search engine gets to know about the content and index it accordingly.

Crawling is the primary step in search engine optimization. If your website is not crawled properly then it will never be indexed. 

Maybe some pages are being crawled and indexed, but you cannot be completely sure about this.

Check and optimize your robot.txt file and .htaccess file. It discloses you about the block URL, file, or folder.

2. Indexing Checkup

After crawling the pages of the website, search engines index them. The search engine never indexes all the pages.

In indexing checkup, we only see which of our pages have been indexed and which are not. So that by solving the problem coming in uncrawled pages, you can index all your useful pages.

There are a lot of indexing issues, you should explore and find yours.

3. Sitemap Checkup

Many people miss the checkup of Sitemap even though it is a very interesting point. The sitemap can also create and solve the problem of both crawling and indexing.

If a page is not linked internally, externally to another page and is not found in the sitemap, then that page will not be crawled or indexed.

Make sure the sitemap is created or not, if it is created, it has been submitted to Google Search Console and it should be accessible.

4. Mobile Friendliness Test

Mobile Friendliness Test is a mandatory, crucial, and compulsory test. Google crawl pages with smartphone bots. The better your website looks on mobile, it will rank accordingly.

Google has its own tool to do this test. After testing, whatever issue is found, fix it properly and also keep in mind that there should be no difference in the content of mobile and desktop.

5. Canonical Checkup

Canonical tags inform search engines about the same content in two pages and they rank only one of these two.

It is also a major checkup because it points to negative SEO practice.

6. URL Checkup

URL is the address of your page, if it is written incorrectly then no one will get it. The URL must be crisp, concise, and relevant. Random numbers, characters should not be in the URL.

Tools like Ahref and SEMrush give the option to analyze the URL and if your website is small then you can analyze it using an excel sheet only.

7. Meta Data Checkup

Metadata is added to the header section in the aggregate of tags and they give important information to the search engines. These things come in Metadata Checker.

  • Meta Title 
  • Meta Description
  • Meta Robot tags
  • OG tags
  • Twitter Cards

So you have to check all these data on every page and for this, you can use tools like Semrush, Ahrefs.

8. Header Tags

In the Header Tags checkup, you have to correctly implement the tags like H1, H2, and H3. Only one H1 tag in a page is considered SEO friendly and your main keyword should be in H1.

Although header tags are not a direct ranking factor, header tags help to format the content of a page properly and enhance the overall user experience.

9. Content

In on-page SEO, the most important thing is the content itself. In such a situation, you should have control over your language and should also have a command of Vocabulary.

If there are spelling and grammatical mistakes in the content, then it will not rank because Google or any search engine is not an introvert.

Analyze your content and there is no need to see any particular percentage of keyword density. Naturally, publish your page only after reading it like a visitor.

10. Internal Linking Checkup

Internal linking is also a part of on-page SEO, there is no fixed number of internal linking but certain points must be focused on.

  • Don’t use the same anchor text to link two different pages.
  • Don’t link the same pages twice.
  • Keep anchor text relevant.
  • Place your link naturally.

11. Schema Data

Schema data is used to explain your web page to search engines. If search engines understand your pages better, then they will rank them accordingly. 

You can add more than one schema data on a single page, but whatever you are adding more than one schema data on the page, that content should also be visible to human visitors.

12. Page Speed

By the end of August, Google will start counting page speed in the ranking signal, so make sure that you optimize your page for fast speed.

13. Image Checkup

Are your images indexable? Is your image optimized for fast download? There are many such questions, on which you check the image and make it SEO friendly.

Apart from this, also focus on the alt attribute of the images of the pages, and the text with which the images are being used in the page is also a ranking factor.

Always remember that SEO is a practical field, it is less theory and more practice. Therefore, if you implement 8 out of these 12 points perfectly, then you will get great results.

Trust me, finding new methods and practicing the same thing over and over will be of less benefit than it would be. If you focus only on the title and description, it should be attractive enough that people will see, click, read and appreciate it.
