Sogou web spider/4.0(+http://www.sogou.com/docs/help/webmasters.htm#07)

first seen 2026-07-02 13:55 · last seen 2026-10-30 14:30 · JSON

Last 7 days (13 observations)

Distinct clients per day (last 30 days, peak 4/day)

Distinct clients are counted by IP-hash per complete UTC day — unlike observation counts this is insensitive to one chatty client, but NAT merges clients and address rotation splits them.

Co-observed signals

Signals from other families seen in the same observation. A fingerprint spread thinly across many lower-layer signatures is a classic inconsistency signal.
