PageSpeed Insights field data covers real visits from the last 28 days (CrUX). The lab score is one simulated load. A Lighthouse update changes the lab simulation (SEJ).

Judge real speed with field data.

PageSpeed Insights now runs Lighthouse 13.6.0, released Oct 27. Google's Barry Pollard says scores usually come out better, mostly on JavaScript-heavy sites (SEJ).

“Temporarily protect the URL from falling out of the index right away.”

Claude Sonnet picked Shopify's top-ranked catalog product 0 times across six searches. Haiku picked the same product 8% of the time and Opus 20% (SEJ test).

In this test, ranking first in the catalog did not decide the pick. Review counts did more.

1,980 picks.

Three Claude models chose from the same 20 Shopify products and never agreed on the top product. Sonnet's favorite took 94% of its picks on average (SEJ, Slobodan Manic).

DemandSphere put spurious results at about 11% of its daily rank checks since September. Nozzle measured 8.0% of pages as poisoned (via PPC Land).

Two vendors, two numbers, one warning. Audit tracker data before reporting to a client.

1.5x.

Nozzle says swapped-out results hit page 2 one and a half times as often as page 1 (29.9M SERPs). Three in five sat under a clean-looking page 1.

If you only track page 1, you miss the problem.
