New data released by Adobe reveals a significant surge in artificial intelligence (AI) driven traffic to U.S. retail websites. As of March, AI traffic escalated by an impressive 269% over the preceding 12 months, building upon the substantial momentum observed during the holiday shopping season, which saw a 693% increase.
This upward trend continued into the first quarter of 2026, with AI traffic climbing 393% compared to the same period a year prior, underscoring a growing consumer reliance on AI assistants for their online shopping needs.
The impact of AI extends beyond mere traffic volume. The data indicates that AI visitors are demonstrating superior conversion rates, higher engagement levels, extended time spent on sites, and generating increased revenue per visit. This marks a notable reversal from just a year ago, when conventional customer interactions typically yielded greater value for retailers.
Adobe's comprehensive insights are derived from its Adobe Analytics division, which meticulously analyzes over 1 trillion visits to U.S. retail sites. The findings are further substantiated by a survey of more than 5,000 U.S. consumers regarding their use of AI in shopping, alongside evaluations conducted using the company's new AI Content Visibility Checker tool, designed to assess retail websites' accessibility for large language models (LLMs).
According to Adobe's survey, 39% of individuals reported utilizing AI for online shopping, with a striking 85% affirming that AI enhanced their overall experience. These positive outcomes are largely attributed to AI's ability to streamline product discovery, help users pinpoint specific items, and identify relevant discounts. Furthermore, 66% of those surveyed expressed confidence in the accuracy of AI tools for shopping purposes.
Unlike the publishing sector, where AI's influence can lead to a decline in referral traffic, retailers are increasingly incentivized to optimize their digital platforms for AI compatibility.
Adobe's data for March 2026 revealed a record-setting performance, with AI traffic converting 42% more effectively than human customers. This represents a dramatic shift from March 2025, when AI traffic converted 38% less efficiently than non-AI sources.
Moreover, Adobe observed that consumers arriving at a retail site via an AI source exhibited a 12% higher engagement rate compared to those using non-AI channels. These shoppers also dedicated significantly more time to the website, spending 48% longer, and navigated through more pages, viewing 13% more pages per visit.
From a top-line perspective, AI-driven revenue per visit (RPV) stood 37% higher than non-AI traffic as of March. This starkly contrasts with the situation just 12 months prior, when traditional human traffic yielded 128% more value than AI-generated visits.
However, Adobe cautioned that not all retail websites are fully prepared for the AI era. The company's analysis found that approximately a quarter of the content on retailers' homepages, as well as on category pages, has not been optimized for LLMs. Individual product pages fared even worse, with about 34% of these pages inaccessible to AI for proper indexing.
To remain competitive and relevant to modern online shoppers, Adobe strongly advises retailers to prioritize making their websites more accessible and optimized for large language models.
