Google updates Lighthouse scores and adds AI training opt‑out
Google announced an update to its Lighthouse tool that changes PageSpeed lab scores, and introduced a shared opt‑out for AI training data. The changes affect local businesses that rely on PageSpeed insights and want control over how their site data is used for AI.
The SEJ article reports that Lighthouse will now calculate lab scores differently and that Google is offering a unified opt‑out mechanism for sites that do not want their data used to train Google’s AI models.
For a coffee shop, salon, pet groomer or fitness studio, altered PageSpeed scores could influence local SEO rankings and the AI opt‑out could affect visibility in AI‑driven search features.
Check your current Lighthouse scores and test the new opt‑out setting in Search Console to see if rankings or impressions change.
Review your latest Lighthouse report and enable the AI training opt‑out in Search Console this week to monitor any impact on local search performance.
