<h1> tag is missing
This means that the URL in question does not have a header 1 tag.
Why is this important?
The header 1 (h1) tag is considered important to help both users and search engines to quickly understand what content they can expect to find on the page.
If the h1 is not present, this represents a missed optimization opportunity.
What does the Hint check?
