Info

What we look for

The path of these addresses (the part after the domain) holds capital letters.

Why it matters

Many servers treat /About and /about as two different addresses, so one page can be reachable at several, which splits links between them and can look like duplicate content.

How to fix

Use lowercase addresses in your CMS and in links. Where a capitalised address is already in use, send it to the lowercase one with a 301 redirect (a permanent forwarding rule).

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: url.contains_uppercase
crawl.json and the CSV
The crawl JSON names the finding by this id, and so do the CSV and raptor_query.
"check_id": "url.contains_uppercase"
The HTML report
This link opens the finding in the report, and each finding shows its id.
crawl.html#finding=url.contains_uppercase
MCP
raptor_findings with this check_id returns the finding in full, with a fix brief ready to paste into a task. If it didn’t fire, it says why.
raptor_findings {
  "job_id": "...",
  "check_id": "url.contains_uppercase"
}
