Decision rule
The output is a diagnostic handoff, not an automated verdict about indexing or ranking.
Useful starting jobs
Parse a bounded log sample, classify redirect and error patterns, inspect pasted response headers and HTML, or check whether an IP value is public, private, or reserved.
- Crawler candidate inventory
- Status and path distribution
- Redirect and directive capture
- Observed, inferred, and unknown handoff
Where this stops
AnalyseSpider does not currently fetch arbitrary URLs, crawl sites, query Search Console, verify bot IPs, or decide canonical selection. Those need separate evidence and controls.
Client logs can contain personal or confidential data. Minimise the sample before pasting it into any tool, including a local one.
A practical sequence
- Reduce the sample to the affected time and route set.
- Inspect local observations and rejected rows.
- Write the strongest supported hypothesis.
- Verify it in the relevant server, crawler, search-platform, or application surface.
