98% of Consumers Refuse to Buy From AI-Recommended Brands Without Checking Them First
Brands across every industry are racing to get recommended by AI tools like ChatGPT and Google Gemini, treating AI visibility as the next frontier in customer acquisition. However, new research suggests that earning an AI recommendation may be the easy part; what happens next is where most brands will succeed or fail.
According to the 2026 Study: How Consumers Verify AI-Recommended Brands by Idea Grove, only 2% of respondents said they would purchase from an unfamiliar brand based solely on an AI recommendation. The remaining 98% take additional steps before committing, turning to Google, review platforms, brand websites, and personal networks to validate what the AI suggested.
The consumer population has enthusiastically adopted AI tools for the discovery phase of their buying journey, while remaining deeply sceptical about trusting those tools to make the final call. It is a dynamic that CX and marketing leaders should not ignore, particularly as AI-driven discovery increasingly replaces traditional search as the first touchpoint in the customer journey.
AI adoption is running ahead of consumer confidence
According to the survey, 42% of Americans have used ChatGPT to research a product, service, or brand in the past six months. Google Gemini followed at 38%, Microsoft Copilot at 18%, and Claude and Perplexity at 6% each. Google Search still leads at 82% and Amazon at 67%, but the speed at which AI tools have entered the conversation is significant. Two years ago, none of these platforms featured in brand research at all.
The generational divide is the most pronounced finding in the study. Sixty-seven percent of Gen Z respondents reported using ChatGPT for brand research, compared to just 30% of Baby Boomers. College-educated respondents (52%) were also more likely to use AI tools than those without a degree (37%), and parents (50%) outpaced non-parents (36%), likely reflecting the volume of purchase decisions families navigate on a regular basis.
Yet despite this rapid uptake, only 15% of respondents said they fully trust AI recommendations to surface the best options available. Consumers are using AI to discover brands, not to decide between them, which has real implications for how brands compete for attention when AI acts as the middleman in shopping.
After the AI Recommendation, Google Is the Next Stop
When an AI tool recommends an unfamiliar brand, 45% of consumers said their immediate next step is to Google it. Another 18% head to review sites such as Google Reviews, Yelp, or G2. Just 16% visit the brand’s website directly, 9% ask someone they know, and 10% ignore the recommendation entirely. The 2% who buy without any further verification represent a statistical outlier.
Notably, Gen Z, the most prolific users of AI tools by every measure in the survey, did not skip the verification step. Among Gen Z respondents, 43% said they Google the brand, and 25% went to review sites, the highest rate of review-checking across all age groups. Zero percent of Gen Z respondents said they buy without further research, making the generation most comfortable with AI also the most rigorous about fact-checking its output.
Reviews, Search Rankings, and Longevity Drive Purchasing Decisions
The study asked consumers both what they check after receiving an AI recommendation and what builds enough confidence to make a purchase. The answers aligned in a hierarchy.
When asked what they actively verify, customer reviews on platforms such as Google, Yelp, and G2 ranked first at 68%. The brand’s website and its professionalism came second (41%), followed by how long the brand has been operating (35%) and whether it appears prominently in Google search results (27%).
When asked what increases their trust enough to buy, verified customer reviews with a high average rating topped the list at 78%. Google search rankings followed at 71%, business longevity at 69%, and a polished, professional website at 64%. Press coverage in recognised publications came in at 58%, and a visible founder or CEO profile increased trust for 47% of consumers, rising to 57% among Gen Z and 50% among Millennials.
In a direct comparison test, respondents were asked to choose between two brands recommended by an AI tool: one that had been covered in trusted news publications, and one they had never seen mentioned anywhere. Some 69% chose the brand with press coverage, while only 6% said they would be more inclined to explore the unknown brand. Among college-educated consumers, the preference was even more pronounced at 75%.
Most Consumers Do Not Know AI Recommendations Can Be Influenced
The findings reveal that the majority of consumers are unaware of how AI brand recommendations actually work. Nearly half (48%) did not know that companies hire consultants and agencies specifically to get their brands recommended by AI tools. Another 20% suspected it but were not sure. Only 32% were fully aware.
Similarly, 40% of respondents had no idea that AI tools may recommend entirely different brands in response to the same question asked at different times, and only 43% were fully aware of this inconsistency.
The demographic pattern here is consequential. Gen X and Baby Boomers, who make up 45% of the sample, displayed the lowest awareness rates about AI influence, but also the highest levels of general trust in AI-surfaced brands. They are less likely to use AI tools, but when they do encounter an AI recommendation, they are less equipped to evaluate it critically.
Scott Baradell, Founder and CEO of Idea Grove, said that AI is changing where people start their brand research, but has not changed what convinces them to buy. A recommendation opens the door, but what consumers find after that determines whether they move forward.
