A new study from Erlin shows that people who find brands through AI are 3-6x more likely to buy compared to regular Google search. However, only 15% of brands get more than 80% of these high-converting AI recommendations. The report found five structural signals that consistently influence whether a brand is recommended by AI, including clear facts, independent third-party mentions, website structure, updated information, and consistent brand details across platforms.
Why it matters
As more consumers use AI to compare products and make buying decisions, AI recommendation is becoming as important as Google ranking. The study found that by 2028, AI will handle 75% of all Google searches, meaning $750 billion in US revenue will flow through AI recommendations instead of traditional search results.
The details
Erlin tracked 500 brands for six months across ChatGPT, Claude, Gemini, and Perplexity, and found a 9× visibility gap between brands that optimize for AI visibility and those that do not. The report found that AI evaluates fragments of information and assigns confidence to what it can verify, with clear facts, independent mentions, website structure, updated information, and consistent brand details as the key signals that influence whether a brand is recommended.
