What this snapshot suggests

For the question "What's the best AI-powered SEO tool?", the 2 models reporting collectively named 8 distinct brands on July 29, 2026.

Each model led with a different recommendation in many cases. Claude opened with Semrush. Perplexity opened with Semrush. 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 measures across a full prompt set on a schedule, 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.
