AI referrals to U.S. retail sites now convert 90% better than other traffic, Adobe finds
TLDR
Adobe data shows AI referral traffic to U.S. retail sites converts better than other traffic and is growing fast, while the average retail homepage scores 63% on its Citation Readability Score.
Optimixed Overview
Optimixed's original report on this story.
Adobe reports that AI referrals to U.S. retail sites converted 90% better than non-AI traffic in September, after converting 9% worse in August 2025, and that AI-referred visitors spent 73% more time on site and added to carts at a 53% higher rate. Adobe also found the average U.S. retail homepage scored 63% on its Citation Readability Score, with explanatory pages such as setup guides and specifications scoring highest, as first reported by MarTech. The data does not establish that better AI readability causes higher revenue, so Adobe's findings point to tracking conversion and revenue per AI landing page rather than raw referral volume.
