The ChatGPT October 2025 update changed how AI search handles brand visibility, showing a 31% average drop in brand exposure after this update, alongside tougher competition for top spots. With new systems for recognizing and citing brands, marketing leaders need to adapt quickly to stay relevant in an AI-driven search environment where old content tactics no longer work.
How the ChatGPT October 2025 Update Affects Brands
The update on October 18, 2025, brought one of the biggest shifts in AI search algorithms, changing how brands are seen and mentioned. By studying brands with visibility scores from 5% to 95% during this period, we noticed a move to a more structured way of identifying brands. This change impacts digital marketing strategies at a core level.
What Changed in Entity Recognition
ChatGPT started using a specific field, Entity[“brand”, …], for tagging brands consistently after October 18. This technical adjustment altered how AI processes brand data, with a sharp rise in answers using these tags. Brands now need proper structuring in AI systems to gain visibility, moving beyond just content quality to machine-readable formats.
Drop in Brand Mentions
After the update, the average number of brand mentions in ChatGPT responses fell from six or seven to three or four, a cut of 30-50%. Fewer mentions mean less exposure for brands per AI answer, making each reference more critical. Businesses relying on frequent mentions now face a tougher fight for attention.
Citation Sources Becoming Narrower
The update also focused citations on fewer platforms, with Wikipedia and Reddit becoming key sources for AI. This shift sidelines many smaller sources, making it harder for brands to get noticed unless they align with these major platforms or create high-authority content that fits AI preferences.
What This Means for Marketing Leaders
These changes signal a need for new strategies in brand visibility. Content made for human readers won’t cut it with AI systems that favor structured data and specific authority markers. Marketing leaders must pivot to meet these technical demands.

Analyzing the Drop in Brand Visibility After the Update
Post-update data shows a broad 31% decline in brand visibility, affecting over 85% of brands. This widespread drop points to a major shift in how ChatGPT prioritizes brand information, impacting even well-known names with strong online presence.
Breaking Down Visibility Losses
Visibility declines varied across brands. About 13% saw major losses of over 10 percentage points, a significant hit to their market position. Meanwhile, 58% faced moderate drops between 2 and 10 points, still a notable challenge in a competitive AI search space.
Tighter Competition Due to Narrowing Gaps
The update squeezed the visibility gap between top brands by 23%, with the difference between the #1 and #10 spots shrinking by the same rate. This tighter field means leading brands can’t rely on past advantages, while competition heats up for every position.
