8.1M-Search Audit Shows Google Randomizes Local SERPs, Possibly Trapping CTR Bots

An analysis of 8.1 million organic grid searches reveals Google elevated SERP volatility by 48.7% post-May 2026, with one theory attributing this to a crackdown on artificial engagement, notes Joy Hawkins.

Instead of stabilizing after the core update, 97% of tracking reports shuffle positions constantly.

The algorithm targets explicit geo-queries — such as category plus city combinations — forcing domains to alternate between ranking and non-ranking coordinates across adjacent grid points.

Logged-out incognito testing confirms this stems from algorithmic randomization rather than user personalization.

Separately, this persistent shuffling may trap automated CTR manipulation.

When the algorithm randomly drops a domain from position three to position six, it monitors the incoming traffic volume.

If the URL continues receiving uniform click volumes despite the lower visibility, the system logs an immediate statistical footprint of synthetic bot engagement.
