About this check

What the tool checks

Review crawl activity recorded by the server while keeping raw log lines and client addresses on the current device.

How this check works

The browser parses bounded common or combined access-log lines and aggregates methods, status groups, hours, paths and crawler-like user agents.
Query strings are inspected for session identifiers, tracking fields and high-cardinality parameter patterns, while client IP values are excluded from the report.

What this check cannot establish on its own

A crawler name in User-Agent is only a claim. Verification requires the operator’s documented reverse- and forward-DNS procedure.
Unparsed lines are counted, not guessed, and a limited time range may not represent the site’s normal crawl behaviour.
