Technical SEO & crawling
Crawls & logs
What it's for
The crawl history and per-crawl log: what was fetched, status codes, redirects, blocked/again-skipped URLs and why a crawl stopped. Your audit trail when results look surprising.
When to use it
- When a crawl found fewer pages than expected.
- To diagnose robots.txt blocks, redirect chains or server errors.
How to use it
- Project → «Logs» (or open a crawl from the history).
- Filter by status code to find 4xx/5xx and redirects.
- Cross-check a surprising URL against its fetched status.
Reading your results
For each output: is it good, does it need improvement, or is it bad — and exactly what to do next.
HTTP status mix
Good
Mostly 200s with intentional 301s: healthy.
Needs improvement
Many 301/302 chains: wasted crawl budget — flatten them.
Bad
4xx/5xx present: broken links or server faults to fix now.
What to do next
Fix 5xx with your host/ops; 404 → restore the page or 301 it to the best replacement.
Next steps
- After fixing redirects/errors, re-crawl and confirm they're gone.
- If pages are missing, check robots.txt and internal links to them.
