AI summaries cut clicks to websites
Pew Research Center found Google users who saw an AI summary clicked a traditional result link in 8% of visits, compared with 15% of visits without one. Users clicked a link inside the summary itself in just 1% of visits.
What these numbers mean for your business
Fewer clicks reach websites when AI answers appear, so being the business named inside the answer matters more. That means clear answer-first content, consistent brand facts and strong rankings, which AI tools use when choosing sources.
