How often is SeznamBot impersonated?
Our verification data for SeznamBot was incomplete during the measurement window, so a share would overstate impersonation. We show none until it is complete.
This directory measures requests between 3 July 2026 and 28 September 2026. The fake crawler report covers its own, earlier window (late June to 21 September 2026), so its figures differ from the ones here. Read it for the method.
