Every time ChatGPT, Gemini, Claude, or Perplexity answers a buyer’s question without naming you, it names someone else. Tracking competitor rankings in AI search shows you who is winning your conversations, and gives you the map to take them back.
A Google results page has room for everyone. An AI answer names two or three brands, sometimes one. That makes AI search closer to a winner-take-most market, and it makes knowing your competitors’ share of answers more urgent than knowing your own mention count.
Take your ten highest-value buyer questions. Run each through the four assistants in fresh sessions. For every answer, record every brand named and the order they appear in. The result is a share-of-voice table that usually surprises people: the competitor winning AI answers is often not the one winning Google.
Assistants weigh different signals: presence in comparison articles and directories, review consensus, clear category positioning, quotable content. A mid-sized competitor with a crisp “best X for Y” footprint can outrank an enterprise with ten times the domain authority. That asymmetry is your opportunity.
When a competitor keeps getting named, ask why. Check the citations in Perplexity and Gemini: which pages carry their recommendation? Usually it is a handful of listicles, review profiles, and category pages. That citation footprint is a checklist, and closing it is exactly the execution work Aethon ships for clients.
Weekly tracking reveals momentum: a competitor entering answers they never appeared in, or fading from ones they owned. Rising mention rates usually trail fresh content and citations by a few weeks, so deltas give you early warning of a rival’s AI strategy while there is still time to respond.
Yes. Run a fixed set of buyer questions through ChatGPT, Gemini, Claude, and Perplexity on a schedule and record every brand named. Platforms like Aethon automate this and report share of voice over time.
The percentage of answers to a question set in which your brand appears, compared against each competitor. It is the closest AI equivalent to rank position.
AI assistants weigh third-party consensus, comparison content, and clear positioning more heavily than raw domain authority. Different signals produce different winners.
Check the sources it cites, especially in Perplexity and Gemini. The citing pages reveal which content carries the recommendation, and where you need presence.
It depends on the gap, but citation fixes and new comparison content often move answers within weeks. Aethon tracks the movement so you see progress against each rival.
