How often is OAI-SearchBot impersonated?

For the median organisation, 11% of requests claiming to be OAI-SearchBot failed verification.

Measured between 14 July 2026 and 10 October 2026 across organisations protected by Centinel. We only publish a share when at least five organisations each saw enough of these requests. Pooled across all of their requests, the share was 4%: a few large organisations carry most of the traffic, so the median organisation is the better guide to what yours will see.

This directory measures requests between 14 July 2026 and 10 October 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.

What blocking changes

robots.txt only asks. It does nothing against a client that ignores it or only pretends to be OAI-SearchBot. Stopping those takes verification at your edge.
