By no means do I use their estimated traffic metric as gospel, but it’s real bad now. AI overviews and other SERP features may appear as top 3, but that doesn’t mean the site will actually get that traffic. IIRC, the CTR per rank formula is basically #1 gets 30% of search volume, #2 gets 15%, etc. but in 2026 that’s so skewed and not a reliable indicator, and doesn’t account for all the SERP features that appear. No one is clicking your AI overviews source link as much as if it was #1 on 2005 Google. They need a better formula, anything that’s slightly closer to reality.
