AI Visibility Index: Who’s Leading in AI Search?
▼ Summary
– Semrush Enterprise created the AI Visibility Index to study how brands perform in leading AI search engines like ChatGPT and Google AI Mode.
– The Index analyzed 2,500 prompts across five industries, revealing a new visibility hierarchy based on mentions in AI responses rather than traditional rankings.
– Top Google rankings no longer ensure visibility in AI search, which instead rewards structured data, transparent pricing, and third-party validation.
– Brands mentioned in AI-generated answers gain much higher visibility than those just used as sources, and iconic names win through consistent, structured signals.
– User-generated content like forums and reviews has become a key driver of brand visibility in AI search, offering a data-backed blueprint for growth.
A significant shift is underway in how consumers find products and services, with AI search engines like ChatGPT and Google’s AI Mode fundamentally altering the digital landscape. While some companies watch their website traffic decline, others are successfully adapting their strategies to capture attention within these new conversational interfaces. The AI Visibility Index, developed using the Semrush Enterprise AI Optimization platform, provides a clear picture of this transformation by analyzing thousands of real user prompts across major sectors.
This comprehensive study examines performance within five critical industries: Business & Professional Services, Digital Technology & Software, Consumer Electronics, Fashion & Apparel, and Finance. It identifies the brands that are leading the pack and, more importantly, reveals the specific tactics driving their success. The findings indicate that a new hierarchy of visibility is emerging, where being mentioned in an AI’s response carries more weight than traditional search engine rankings for building brand awareness and influencing purchasing decisions.
One of the most critical insights is that SEO does not automatically translate to AI visibility. A top position on Google no longer ensures you will appear in ChatGPT or similar AI tools. These models operate on different principles, favoring brands that provide structured data, clear and transparent pricing information, and possess strong validation from third-party sources.
Furthermore, there is a distinct difference between being a source and being cited. A brand might supply the data an AI uses to form an answer, but that does not equate to visibility. Brands that are explicitly named and discussed in the AI’s final generated response achieve exponentially greater recognition than those that merely serve as background data points.
The research also highlights the power of established brand authority. Iconic companies such as Patagonia and Garmin consistently perform well by dominating their respective niches. They achieve this through a steady stream of clear, structured signals that AI models can easily recognize and trust. In a surprising turn, user-generated content has become a primary driver of authority. Forums, review sites, and authentic user discussions are now pivotal in determining which brands an AI search engine will recommend to its users.
This report goes beyond simple rankings to explain the decision-making process of AI models. It provides marketing leaders with a data-backed framework for growth, helping them understand the crucial gap between which brands an AI talks about and which ones it truly trusts. By aligning strategies around discovery, authority, and sentiment, businesses can systematically engineer their AI visibility rather than leaving it to chance.
The AI Visibility Index offers one of the first evidence-based roadmaps for how companies can ensure they are found, trusted, and actively recommended by artificial intelligence across all major platforms. For any brand looking to understand its competitive standing and learn what it takes to lead in this new era, exploring this index is an essential first step.
