About this check

01

What does this tool check?

We map the full h1–h6 outline, flag skipped levels, duplicate or missing h1s and empty headings, and check the title length, meta description and html lang attribute.

02

How should I read the result?

Heading structure is how machines infer your page outline — a skipped level (h1→h3) breaks the tree. Length guidance for titles (~60 chars) is convention, not a hard rule.

03

What should I do next?

One h1 per page, no skipped levels, and a description that answers "what will I find here" in one sentence.
