About the H1 & Heading Structure Checker
Headings give a page its structure. They help readers skim, help screen reader users navigate, and help search engines understand how topics on the page relate. This heading checker fetches a public URL and shows its H1 to H6 headings as an indented outline, so you can read the page's skeleton at a glance.
It checks for a single H1, empty headings, skipped levels such as jumping from H2 to H4, and very long headings that read more like paragraphs. Themes often misuse headings for styling, for example making sidebar widget titles H2s or the logo an H1. Fix those in your template, and make sure the H1 clearly describes the page's main topic. You can copy the outline to share with writers or compare with competitors.
How to use it
- Enter the URL of the page to check.
- Run the checker to build the heading outline.
- Review warnings for missing or multiple H1s, empty headings and skipped levels.
- Fix headings in your editor or theme, then copy the clean outline if needed.
Frequently asked questions
Can a page have more than one H1?
HTML allows it, and Google has said multiple H1s are not a problem for its systems. Still, one clear H1 that states the main topic is the simplest and most accessible pattern, especially for screen reader users. Multiple H1s usually come from themes using H1 for logos or section titles, which is worth tidying.
Does skipping heading levels hurt SEO?
Search engines are unlikely to penalise a jump from H2 to H4. The bigger impact is on accessibility, because assistive technology users rely on a logical heading order to navigate. A clean hierarchy also makes content easier to scan and maintain. Choose heading levels for structure, and use CSS for visual size.
Should my H1 be the same as my title tag?
They can be the same or similar, and keeping them aligned helps Google trust your title. The title tag is written for search results and often includes the brand, while the H1 is written for people already on the page. Both should describe the same main topic in natural language.
