Semrush Publishes Expanded 2026 AI Visibility Index
Semrush, an Adobe company, published the 2026 AI Visibility Index analyzing 126 million U.S. AI search prompts collected from January through April 2026. The expanded study scales Semrush’s earlier index from 2,500 prompts to a much larger dataset and benchmarks brand mentions, citations, and visibility across four major AI search environments. The report finds large sector differences in AI visibility concentration, highlights that only 36 global brands retained top-100 visibility across all four platforms, and shows publishers and third-party sources now heavily influence AI brand narratives. Adobe data cited in the release shows dramatic growth in AI-driven traffic to retail and travel sites. Semrush and Adobe argue brands need integrated SEO, content, data and governance strategies because many marketing leaders lack tools to measure AI visibility consistently across platforms.
The report quantifies how AI-driven search changes brand discovery and citation patterns across major AI search environments, highlighting measurement gaps and practical implications for SEO, content, and brand governance — relevant to marketers and measurement teams but not an industry system-level policy change.

Boost Your Brand's Visibility in AI Search Today!
In a recent AdExchanger Talks episode, Tracy Morrissey, SVP of Media & Performance at Innocean USA, explains how brands can gain visibility in AI-generated search. She warns that you cannot simply bid your way to the top of large-language models; success hinges on creating content that directly answers real questions and on understanding how prompts indicate user intent. Brands should publish information on trusted sources—Wikipedia, retailer sites, and a brand’s own site—and verify origins by tracing sources used by AI. The episode notes firms that measure how often brands appear in AI search results, including Profound, Bluefish, and Semrush; it also notes Semrush was acquired by Adobe for $1.9B a week after recording. Morrissey discusses AI tool fragmentation, the need for better orchestration, the enduring value of human guidance in media planning, and a personal note about how dog training influenced her leadership.

Andrew Warden, Semrush’s CMO, is quoted describing the change and strategic rationale.
