Frequently asked questions
How many H1 tags should a page have?
One H1 per page is the common best practice because it states the main topic clearly.
Does skipping heading levels hurt SEO?
It is not a direct penalty, but a clean H1, H2, H3 order helps readers and screen readers follow your content.

No. The check runs in your browser.
