Checklist for on page SEO

If done rightly, optimization of on-page elements can significantly improve the rankings of the webpage. Some of the most important on-page ranking factors are:

Importance of content for SEO:

What is a good Content in SEO?

From an SEO Perspective, content is considered as good content if it is linked and shared by other people on the internet and it supplies the demand of a large audience be it a web 2.0 submission that provides complete information about it.

What is a Duplicate content in SEO?

The appearance of the same content at different web addresses over the internet is called duplicate content or plagiarism.


Providing an accurate title to content written is the second most important ranking factor. 

The title tag gives important information about what type of content is present on the page to search engines and users in SERPs.

The number of characters displayed in SERPs is limited to 60 characters remaining characters are truncated.

Meta Description

The meta description is used to provide the summary of the content that the users are going to view after landing on the page.

Meta Description character limit is set to 160 characters remaining characters are truncated.

Providing more than 16o characters may not affect your SEO rankings.

Now, Search engines will automatically pick meta descriptions from the content on the page according to users’ queries.


Website URL structure must be well-crafted to provide users and search engines the page they are going to view from the SERPs and also to make users easily navigate through the site to find additional information.

Example of well-optimized URL structure of a site:


Alt-text or alt attribute is part of the IMG tag that describes the function and appearance of an image on a webpage.

Example of Optimized Alt text:


The use of canonical tags helps search engines understand the master copy of a page and which page should be shown in SERPs. It prevents duplicate issues on e-commerce sites with similar content on common product pages with slight changes in size, cost, and color.

Example of using the well-optimized canonical tag: (master or main page with all colored Nike shoes)

If filters are applied by the consumer based on red color: (same content is present on different URL)

If filters are applied by the consumer based on blue color: (same content is present on different URL)

Search engines may consider these pages as separate pages hence the issue of duplicate may arise. 

To indicate search engines about filtered pages are the pages from the master page canonical tag must be implemented on these filtered out pages.


Meta directives:

Meta directive is a piece of code that instructs crawlers how to crawl and index a page on a site.


HTTP Status code:

HTTP status code is 3 digit response code sent by the server in return for the user’s request of a webpage over the internet through a browser. some important http status codes are 404 (page not found) error, 410 (page gone) etc. You can check the crawl and index errors in search console and fix them.


Headings are like signboards to readers and search engines. These headings help readers quickly scan the page to find the content they are looking for. Headings make readers understand what the paragraph or section is about.

Headings range from H1 to H6 with H1 being the most important and it is used to mention the main topic of the page and H2 to h6 are used to mention the subtopics and subsections of a page.

Try to include the primary target keyword in the H1 tag.

How to Structure your content with headings?

Structure your heading tags effectively. For example, Consider the H1 tag as the name of the book and the h2 tags as the chapters of the book, and h3, h4 as sections of the chapters.
