Frequently Asked Questions
Why do headings matter for SEO?
Headings help readers scan a page and help search engines understand its structure and main topics.
Can a page have more than one H1?
It is allowed, but one clear H1 that describes the page is usually best for readers and for SEO.
What is a skipped heading level?
Jumping from an H2 straight to an H4, for example. It makes the outline harder to follow, especially for screen reader users.
Is the HTML uploaded?
No. The check runs in your browser.
