Key findings
  • Four in five citations (80%) point at third-party pages, mostly "best AI visibility tools" roundups. Vendors' own sites collect only 10% of citations in their own category.
  • YouTube (2,257 citations) and Reddit (1,725) are the two most-cited domains, ahead of every vendor. LinkedIn is fourth.
  • Among vendors, Semrush is cited most (24% of vendor citations), followed by SE Ranking (19%), Profound (17%), Otterly (13%) and LLM Pulse (12%).
  • Google AI Overviews, Google AI Mode, Grok and Claude cited all 25 of the most-cited roundup pages. ChatGPT cited 18 of them, the fewest of any engine.
  • Google's own AI optimization guide is the seventh most-cited third-party page (457 citations) even though it names no tools.

What we measured

AI Rankly tracks the AI visibility and AEO/GEO toolscategory for its own brand, the same way it tracks any customer's. For 60 days ending September 8, 2026, 149buyer prompts (for example "best tools to track brand mentions in ChatGPT") ran every day on 7 engines: ChatGPT, Claude, Gemini, Perplexity, Grok, Google AI Overviews and Google AI Mode. Each full answer was stored, and every URL the engine cited was extracted and grouped by domain and by source type. That produced 65,653 citations. The pipeline is described in full on the methodology page.

Where citations go, by source type

Four in five citations point at third-party pages, and most of those are "best AI visibility tools" roundups. The vendors being recommended collect a tenth of the citations in their own category. If you sell in this category, the pages that decide whether you are named are mostly pages you do not own.

Do the engines cite the same pages?

We took the 25 most-cited roundup pages in the category and checked which engines cited each one at least once. Four engines cited all 25. ChatGPT cited 18, the narrowest set, which is consistent with it drawing on a smaller pool of retrieved pages per answer than the Google surfaces or Perplexity.

What this means if you sell in this category

Being named in AI answers here is mostly decided off-site. The roundup pages above are the ones to be listed on, and YouTube, Reddit and LinkedIn are worth more citations than any vendor blog. Your own site still matters for what engines say about you once you are named (pricing, positioning, facts), but it is not what gets you into the list.
