Layout stability across the web

Google's CLS audit, averaged — a rendering metric, not an agentic one. It has gone up since May 2026, and again last month. Both steps clear their margin.

Layout stability, May 2026 to August 2026, one measurement a month. The last step was a real rise.

What this measures

Lighthouse audit: cumulative-layout-shift

Cumulative Layout Shift, averaged rather than counted. It is a NUMERIC metric, so there is no pass or fail to count — measuring it as binary returned zero measurements, which is how we found out. It is here as evidence and not as a dimension: a rendering metric of a different kind from every other audit in the category, carrying half its weight.

Who moved

How to read these figures

Every figure here comes from a sample, not from counting every site — so it carries a margin: how much it could move if we had happened to sample different pages. A figure measured on a thousand pages has a wide margin; one measured on a hundred thousand has a narrow one. It matters for one thing: two figures that differ by less than the wider of their margins are not one above the other, they are tied. That is why nothing here has a position number.

How many actually moved

1 of the 1 segments measured on both months moved by more than their margin. The other 0 did not move: their difference is smaller than this sample can resolve. All of them are in the table below.

Segment	July 2026	August 2026	Movement
All sites	87.7%	88.6%	▲ +0.9
