BrightEdge, the global leader in enterprise SEO and AI-driven digital performance, released new data showing that AI search engines are actively evaluating brands, with each engine behaving differently. Google's AI Overview is 44% more likely than ChatGPT to surface negative brand sentiment overall, but ChatGPT concentrates its criticism 13 times more heavily near the point of purchase, influencing buyer decision.

Why it matters

For CMOs, the result is a new form of brand risk that cannot be managed by measuring AI visibility alone. Consumers increasingly use AI not just for answers but also for brand evaluation, and AI now delivers its own editorial opinion directly in its responses.

The details

Both engines summarize a brand's entire digital history, including reviews, forum discussions, news coverage, and past controversies, but frame their answers and talk about brands in fundamentally different ways. Google's AI Overviews skew heavily toward controversy-driven negativity, including lawsuits, boycotts, data breaches, regulatory actions, and product recalls. ChatGPT skews toward product-evaluation negativity, including compatibility limitations, feature shortcomings, and 'is it worth it?' assessments.
