Having This Many Heading Sections Is Never Going To Make Sense
Google's John Mueller comment in a post on Reddit by saying that heading section is really used too much. An in-depth heading section like H6 may waste SEO time. He said: “Having this many sections is almost never going to make sense, and changing anything in the last level is never going to change anything with regards to SEO. This is a waste of time when it comes to SEO.“
Changing Between <Heading6> Or <Span> Or <Heading2> Didn’t Work Well In Increase Ranking
He said this is common sense. In addition, someone said: “In this case, changing between <h6> or <span> or <h2> will not result in a significant increase in ranking.” John replied: “Exactly!”
Then, John added: “It's obvious when you just look at the numbers… Assuming you have 3 sub-sections per section, that would be:
1xH1 (insert argument about number of H1s here) * 3xH2 * 3xH3 * 3xH4 * 3xH5 * 3xH6 = 243 headings / sections on this page. “
Therefore, when it comes to Heading, don't be too weedy. In terms of search engine optimization, Google has played down for a while.
