Key Features

Polite crawling

Pages are discovered through internal links, robots.txt is followed and a few pages are fetched at a time within a fixed time budget.

Site-level issues

Broken internal links with the pages that link to them, internal redirects, canonicalized and noindex pages, and thin content.

Duplicate detection

Duplicate titles, meta descriptions and H1s, plus pairs of pages with near-duplicate main content.

Every page audited

Each crawled page gets the full on-page audit, with its score, depth, inlinks and failed checks.

Example request

GET /v1/site-audit?url=example.com&max_pages=25 bash

curl -H "X-API-Key: $DOMSCAN_API_KEY" "https://domscan.net/v1/site-audit?url=example.com&max_pages=25"

Frequently asked questions

How many pages can I crawl?

10, 25 or 50 pages per request. The response says how many discovered pages were not crawled, so you can see the coverage.

Does it follow robots.txt?

Yes. Pages disallowed for all crawlers are skipped. If robots.txt cannot be read, only the start page is audited.

Why are some links not checked?

Only crawled pages are checked. Links to pages beyond the page limit are counted as discovered but not crawled.

How many credits does it cost?

10 credits for 10 pages, 20 for 25 and 35 for 50. If the start page cannot be read, the request is refunded.
