See the H1 to H6 heading structure of a page and its SEO issues.
The heading checker extracts the H1 to H6 tags of a page and shows them as an outline, in the order they appear. It counts each level and flags the common SEO and accessibility problems: no H1, several H1s, skipped levels and empty headings.
Headings give a page its structure. Search engines use them to understand the topics a page covers, and screen reader users jump from heading to heading to navigate.
The headings indented by level, like a table of contents.
Missing, multiple or too long H1.
E.g. an H4 straight after an H2.
Headings with only an icon or an image.
One H1 that describes the main topic is the clearest structure, although Google can handle more.
It's best for accessibility: use H2 for sections, H3 for sub-sections, and don't skip levels.
Yes, naturally: headings that describe the content usually contain the words people search for.
