AI Search Bias: Minuttia Study Reveals Vendor-Generated Lists
Minuttia’s new study shows that AI search tools lean heavily on vendor‑written “best‑of” lists, with 34‑47% of alternatives lists and 56‑65% of comparison lists coming from the vendors themselves. Those lists place the vendor’s product first 87% of the time, and only 16% disclose the source.
Key Highlights
- ✓Up to 65% of 'X vs Y' lists cited by AI are vendor-written.
- ✓87% of biased lists rank the vendor's own product first.
- ✓Only 16% of these pages disclose they were written by the vendor.
- ✓The study analyzed 18,084 questions across 6 major AI platforms.
AI Search Bias: Minuttia Study Reveals Vendor-Generated Lists
The rise of AI search tools like ChatGPT, Perplexity, and Google AI Overviews has reshaped how businesses are discovered online. Yet Minuttia’s latest research uncovers a troubling bias: a large share of the "best tools" lists that AI cites are authored by the very vendors whose products they rank.
What Happened
On Friday, October 23, 2026, Minuttia—a top SEO and AEO agency for SaaS firms—published the Self‑Promotional Content Data Study. The researchers examined 18,084 software‑related questions across six platforms: Google Search, AI Overviews, ChatGPT, Gemini, Claude, and Perplexity. Their focus was on two question types—alternatives and direct product comparisons.
The Numbers Behind the Bias
The findings paint a stark picture of how AI crawlers source content:
- Alternatives Questions: Between 34% and 47% of the listicles cited are written by the product’s vendor.
- Comparison Questions: The share jumps to 56%–65% for "X vs Y" queries.
- Ranking Bias: In vendor‑authored lists, 87% place the vendor’s own offering at the top.
- Disclosure Gap: Only 16% of those pages clearly state that the vendor authored the content.
- Floor Effect: The study calls these figures a "floor," meaning the real level of bias could be higher because not every page could be examined.
What It Means for Your Business
#### 1. The Trust Gap
When a small‑business owner asks ChatGPT, "What is the best CRM for small business?" and the AI returns a Salesforce‑written list that ranks Salesforce first, the recommendation feels self‑servicing. Trust erodes quickly when users suspect the source is biased.
#### 2. The Need for Objective Citations
VisibilityAI helps you break through the echo chamber by securing citations from neutral analysts, reputable media outlets, or industry bodies. AI tools value high‑quality, unbiased data, and third‑party endorsements carry far more weight than vendor‑generated lists.
#### 3. Monitor Your Citations
You can’t improve what you don’t track. Use monitoring tools to see whether you appear on vendor‑written lists or in independent comparison pieces. Knowing where you show up is the first step toward reclaiming visibility in AI‑driven search.
Key Takeaways
- Up to 65% of AI‑searched lists are biased: The "X vs Y" category is the most affected.
- Vendor bias is systemic: 87% of those lists put the vendor first.
- Transparency is rare: Only 16% disclose authorship.
- Quality matters: AI can surface any data, but user trust hinges on the credibility of that data.
Why This Matters for VisibilityAI
The study validates VisibilityAI’s mission: as AI search becomes more transparent, the reliance on self‑promotional content becomes a liability for vendors. While large players can flood the ecosystem with their own lists, they cannot easily manufacture an objective reputation. By focusing on third‑party citations, local and small businesses can rise above the noise and become the trusted recommendation that AI platforms are eager to display.
Why This Matters For Your Business
The findings expose an "echo chamber" risk in AI search—if algorithms primarily draw from vendor‑authored lists, users receive recommendations that are more marketing than merit. This distortion can mislead decision‑makers, steering them toward solutions that may not truly fit their needs. For business owners, the implication is clear: a strong web presence is no longer enough. You must earn citations from neutral, authoritative sources if you want AI assistants to surface your product as a genuine option. VisibilityAI’s services are designed to build that third‑party credibility, turning the bias revealed by Minuttia into a strategic advantage for smaller players.
