One of the most powerful ways to tell your users all about your write-up and web page is to make use of h1 tags in every one of each page.
There are other headers tags with different levels (h2,h3,h4...) but in terms of SEO, the h1 tag is the most important.
The h1 tag which is also known as the header tag or the <h1> tag in HTML (an acronym for HyperText Markup Language) can be said to be the title of the page or any other emphasized text on the page.
This doesn’t mean that the h1 tag must be the title of the page as there are cases where the header tag and title of the page are different from each other.
Why Is It Important?
As said earlier, the h1 tag or the title of the page is a great way to summarise to your visitors what a particular web page is all about. H1 is also one of the most important tags in HTML in terms of SEO performance.
When writing an h1 tag, it is essential to make use of keywords to help increase optimization and increase your chances of being recognized by search engines.
Try to resume the main content of your article, thinking in a phrase that your readers would find attractive and useful. Also, try to use the main keywords of the topic. Getting powerful h1 tags and titles is not an easy task, but a good suggestion would be to revise your article once written to see if it can be improved.
For instance, an excellent h1 tag for an article talking about SEO and its strategies would be “All you need to know about SEO” or “The top 10 SEO strategies.” A bad example would be “Article on various strategies.”
Did you know? For SEO purposes, it is mandatory to use one and only one h1 tag on a website tag. Instead of using more than one h1 tag you can use h2, h3, h4 tags in your articles.
Expert’s suggestion: What is ultimately the most important are the many signals (of which H1 is one) that make up a page and indicate what the topic of the page is.” – Jenny Halasz (https://www.searchenginejournal.com/how-important-is-h1-tag-for-seo/261547/#close)
