AI Visibility Index: Who’s Leading in AI Search?
▼ Summary
– Semrush Enterprise created the AI Visibility Index to analyze how brands perform across leading AI search engines using 2,500 prompts in five key industries.
– AI visibility differs from traditional SEO, as top Google rankings no longer ensure placement in AI results like ChatGPT or Google AI Mode.
– Brands mentioned in AI-generated answers gain significantly more visibility than those merely used as data sources, emphasizing the importance of citations.
– Iconic brands such as Patagonia and Garmin succeed by establishing consistent, structured visibility signals to dominate their niches in AI search.
– User-generated content from forums and reviews has become a key driver of brand visibility, offering a data-backed blueprint for marketing leaders to grow their AI presence.
A significant shift is underway in how consumers discover products and services, with AI search engines like ChatGPT and Google AI Mode fundamentally altering the digital marketing landscape. While some companies watch their website traffic decline, others are actively adapting their strategies for this new channel and reaping the rewards. To provide clarity in this evolving space, the AI Visibility Index was created as a comprehensive analysis of brand performance across the world’s most prominent AI search platforms.
This definitive study leverages a sophisticated AI Optimization platform to examine 2,500 real-world user prompts across two major AI systems. The research focuses on five critical industry sectors: Business & Professional Services, Digital Technology & Software, Consumer Electronics, Fashion & Apparel, and Finance. The findings reveal a new hierarchy of digital visibility, where mentions within AI responses are now more influential than traditional search engine rankings for building brand awareness and driving purchase decisions.
The research highlights several crucial insights for modern marketers. First, a strong position in Google’s search results does not automatically translate to visibility in AI-powered answers. These new models prioritize different signals, favoring brands that provide structured data, clear pricing information, and robust third-party validation from credible sources.
Furthermore, the study makes a critical distinction between being a source and being cited. A brand might supply the data an AI model uses, but the companies that are explicitly named and discussed in the final answer achieve dramatically higher visibility. This creates a powerful “brand effect,” where established names like Patagonia and Garmin dominate their categories by consistently providing the structured signals that AI models look for.
Perhaps one of the most significant findings is the rising authority of user-generated content. Forums, product reviews, and authentic user conversations have become primary drivers for brand visibility within AI search, often outweighing traditional corporate messaging.
Beyond simply ranking the top performers, the AI Visibility Index decodes the underlying mechanics of how AI models select which brands to present. It provides a data-backed blueprint for marketing leaders, helping them understand the gap between which brands AI talks about and which ones it truly trusts. The report offers actionable strategies for aligning key factors like discovery, authority, and overall sentiment to engineer AI visibility deliberately.
This study provides one of the first evidence-based frameworks for how companies can be found, trusted, and actively recommended by AI across all major platforms. Success in this new era is not a matter of chance; it is the direct result of a carefully engineered strategy tailored to the unique logic of artificial intelligence.
