PageSpeed & Performance

November’s announced redesign makes the distinction between real-use evidence and a controlled Lighthouse test easier to discuss.

June’s rollout makes real-use evidence and controlled diagnostics more valuable than treating one lab result as a ranking prediction.

April’s update shifts the announced start towards mid-June and adds reporting tools; the preparation should follow customer friction.

November’s announced May 2021 target gives site teams time to prioritise actual usability problems rather than chase a last-minute score.

Lighthouse 6.0 changes the performance score, making test conditions and individual diagnostics more useful than a lone badge.

Google’s new May 2020 metrics focus attention on loading, the first interaction and unexpected movement.

Search Console’s experimental Speed report groups similar URLs. Use that view to identify shared causes and choose a repair with a wider effect.

Lighthouse now supports performance budgets. Use a shared allowance to discuss the cost of a new feature before it slows the public site.

PageSpeed Insights now uses Lighthouse. Read a controlled test and real-user history as different kinds of evidence before setting the next task.
