What this snapshot suggests
For the question "What's the best marketing automation platform for a B2B SaaS company?", the 4 models reporting collectively named 15 distinct brands on May 13, 2026.
Each model led with a different recommendation in many cases. ChatGPT opened with HubSpot. Gemini opened with HubSpot Marketing Hub. Claude opened with HubSpot. Perplexity opened with HubSpot Marketing Hub. The brand a model names first carries disproportionate weight, because first-place recommendations are the most likely to be remembered by readers and quoted by downstream AI agents.
Treat this as a snapshot, not a definitive ranking. AI Overview content changes 70 percent of the time for the same query, and SparkToro found less than a 1-in-100 chance that two identical queries return the same brand list. The pattern across many runs is more informative than any single result. That is why Honeyb runs measurements daily, across a full prompt set rather than a single question, for the brands we monitor.
If your brand appears here, the recommendation work is paying off. If it does not, the gap is measurable and improvable. The pillars of getting recommended by AI are documented in our guide to generative engine optimization.
Source domains AI cited
Most-cited domains across the four models. Stacked segments show which engine drove each citation. Perplexity and Claude expose citations consistently; ChatGPT and Gemini do so inconsistently, so absence does not mean a model used no source.
