Headings structure your page for readers and Google
Headings work like a table of contents. The H1 states the page's main topic, H2s are its main sections, and H3s sit under those. A clear structure helps readers scan, helps screen readers navigate, and helps Google understand which parts of the page answer which questions.
Common problems are a missing H1, several competing H1s, skipping from H2 to H4, and headings used just for styling.
Tips for using the heading tag checker
Make headings descriptive
"How to clean cast iron with salt" helps readers and Google; "Step 2" doesn't.
Use headings, not bold text
Bold paragraphs look like headings but don't give the page structure.
Use questions people ask
Get real questions from the people also ask tool and use them as H2s.

Heading Tag Checker FAQ
Can I check any website?
Any public page. Pages behind a login, or that block automated requests, can't be checked.
Is more than one H1 bad?
Google says it isn't a problem technically, but one clear H1 is still best practice for clarity and accessibility.
Is it free?
Yes, with no sign-up. Page checks are limited to 60 a day per person to keep them fast for everyone.
Should every page have an H1?
Yes, one H1 that states the page's main topic.
Do headings affect SEO?
Yes. They help Google understand the page's structure and which section answers which question.
Can I skip heading levels?
It's best not to. Skipping from H2 to H4 confuses screen readers and outline tools.
