What we look for

The first H1 heading (the main heading at the top of a page) on these pages matches the first H1 of another crawled page. Pages kept out of search, or that name another page as the one to show, are left out.

Why it matters

The main heading tells visitors and search engines what a page is about, so pages with the same one look as if they cover the same thing.

How to fix

Rewrite each page's main heading in the CMS or page template so it names that page's own topic.

Seen in a real crawl

From a crawl of Kestrel Bay Digital (the canonical-variants fixture), a test site from Raptor’s fixture suite.

Where you’ll see it

The id is stable, and every surface uses it, so it’s the thing to search for or hand to an agent.

Terminal
When it is one of the five findings under Fix first, raptor crawl prints the id under it.
Check: headings.h1_duplicate
crawl.json and the CSV
The crawl JSON names the finding by this id, and so do the CSV and raptor_query.
"check_id": "headings.h1_duplicate"
The HTML report
