Key Takeaways
- The Idea Grove survey found only 2% of consumers would buy from an unfamiliar brand based only on an AI recommendation, while 98% take extra steps to verify it.
- Google search, customer reviews, press coverage, and brand longevity remain key trust signals after AI introduces a brand.
In the age of AI, B2B marketers are are racing to get recommended by AI tools like ChatGPT and Google Gemini. But new research shows that a recommendation alone does not close the deal.
In the Idea Grove 2026 Study: How Consumers Verify AI-Recommended Brands, just 2% of 1,000 U.S. consumers surveyed by Pollfish say they would purchase from an unfamiliar brand based solely on an AI recommendation, while 98% take additional steps before deciding.
The report found the outsized role that Google continues to play: 45% immediately Google the brand, while 18% go directly to review sites, making search and reviews the next step after AI discovery. And 71% rely on Google search rankings and 69% value business longevity
Why AI Discovery Is Only the Beginning
The findings highlight a clear pattern: AI is accelerating discovery, but consumers still rely on external validation to make decisions.
“AI is changing where people start their brand research, but it hasn’t changed what convinces them to buy,” said Scott Baradell, founder and CEO of Idea Grove. “A recommendation opens the door. What consumers find after that determines whether they move forward.”
How Much Trust is Their for AI Search
Idea Grove is a Dallas-based public relations and visibility agency specializing in helping B2B brands build the authority that gets them recommended by humans and AI. The agency’s Total Visibility System is built on the Trust Signals Framework and integrates earned media, SEO, and thought leadership into a unified strategy for AI-era brand authority.
The report found overall trust picture remains cautious. Only 15% of consumers believe AI recommendations are generally the best options available. 40% are pragmatic skeptics who use AI but don’t fully trust it. 27% are actively skeptical, believing AI may favor brands that have figured out how to game the system. And 19% don’t trust AI recommendations at all.
Other key findings of the report include:
- 78% say customer reviews increase trust, ranking as the most influential trust signal after an AI recommendation
- 58% say press coverage increases trust, and 69% are more likely to choose a brand with media coverage over one with none
- 42% of Americans now use ChatGPT for brand research, signaling rapid adoption of AI tools in the discovery phase
- 48% of consumers don’t realize companies actively try to influence AI recommendations
“Consumers treat an AI recommendation as a starting point, then fall back on the same signals that have always built trust — reviews, press coverage, search rankings, a credible web presence,” said Baradell. “What’s striking is that AI systems themselves were trained on those same signals. The evidence that makes a brand credible to a careful human buyer is the same evidence that makes it credible to the machines. “
