Inaccessible websites fail AI shopping agents as consumer…

AudioEye's September 24 study clocked AI agents at 31% task completion on an inaccessible site versus 96% on an accessible version, the same day NielsenIQ said 51% of U.S. consumers now use AI to shop.

Two studies landed on the same day, September 24, and together they redraw the map of who can actually reach an American consumer online. NielsenIQ reported that 51% of U.S. consumers had used at least one AI-powered tool to help them shop in the previous month, the first reading above half in its Agentic Commerce Tracker and a nine-point jump from the 42% recorded on May 5. Hours earlier, Tucson-based AudioEye (Nasdaq: AEYE) published a study finding that AI agents completed 96% of tasks on an accessible version of a test site and just 31% on the inaccessible version of the same site.

Read those numbers together and the implication is blunt. The majority channel for U.S. consumer shopping is now mediated by software that, per AudioEye CEO Kelly Georgevich, agents “use a website’s accessibility tree, not the DOM, which powers web browsers.” If the tree is broken, the customer isn’t browsing your store. They’re bouncing off it, silently.

AudioEye’s methodology is worth reciting because the design anticipates the obvious objection. Researchers ran 1,560 AI agents drawn from six commercial models across 13 real-world tasks on six websites (five retail, travel and DTC properties, plus W3C’s demonstration site), repeating each test 10 times. Task completion on the least accessible site fell by roughly two-thirs. One unlabeled-image task failed on all 60 attempts. Scoring was cross-checked by WebJudge, the open-source evaluator from Ohio State University’s NLP group, which agreed with AudioEye 95% of the time. The caveat, flagged by The Agile Brand Guide, is that AudioEye published site-level completion rates only for its worst performer and sells the remediation it tested.

The cost story is quieter but sharper. Median token consumption rose 43% on inaccessible pages, from 90,000 to 128,000, and the priciest model burned six times as many tokens on the worst site. Agents pay to guess.

NielsenIQ’s sample, roughly 500 U.S. consumers monthly with a margin of about plus or minus 4.4 points, also breaks out the behaviors driving that 51% headline: 20% now use AI-powered product recommendations, and 16% use personal shopping assistants. “Just months ago, AI-assisted shopping was viewed as an emerging behavior among early adopters. Today, it is now mainstream. The path to purchase is rapidly evolving from search-driven to AI-driven, and that change is happening faster than many organizations realize,” said Liz Buchanan, NIQ’s president for North America.

The context is a distribution shift already in motion: Meta launched its Muse personal agent in September into a family of apps reaching more than 3.6 billion people daily, an arrival we covered last week, while Cloudflare’s crawler-default flip rewired what agents can even fetch. Accessibility has quietly become the last mile of that pipeline. Screen-reader compliance, once framed as a legal obligation with a narrow user base, is now the interface layer for the majority customer.
