Proper use of the heading tag is crucial in the search engine positioning. In this test, we see if the single post/page is using the heading tag in the most optimized way.
How to test?
Visit the url of the single post.
View the source code of the post.
Check the heading tags base on the 2 conditions stated below.
Repeat step 1-3 for the single page.
Criteria of passing the test
Only one <h1> tag is used
The reason why only one <h1> tag is used is because having more than one <h1> tag will greatly dilute the weight of the keywords you want to target.
The <h1> tag should be used in the post/page title
The post/page title contains the most important keywords that you want to target for the single post/page so using the <h1> tag in the title will greatly boost the weight of the keywords as seen by search engines.
Since it is a single post/page, the keywords in the <h1> tag will always be static.
