How to read this report
Every figure counts unique domains that visitors and our own checks scanned between 28 September 2026 and 4 October 2026 (UTC). Each domain is counted once per week, bots and blocked or spam domains are removed, and the classification follows the same scoring rules as every report on this site. The sample is made of sites people chose to check, so it is not a random sample of the web: read the shares as a picture of what our users scan, not of all websites.
Want the longer view? The monthly insights and the AI builder market share page put these weekly numbers in context, and the methodology explains what the detector can and cannot see.
