We read and score real business websites the way AI assistants read them. This page covers 922 optician sites, re-read on a rolling cycle. Their average score is 61 out of 100. Every figure below is measured, and moves as the measurements do.
The share of measured sites with each practice in place. Movement compares the current reading window with the one before it, shown only where both windows hold a real sample.

A practice being common among measured sites is a fact about those sites. It is not a promise that adopting it gets a business recommended, and we publish our research on that question separately as it is measured.
The same checks behind these figures run on any site, free, in about a minute.
