There are four causes and they are separable. First, reachability, an AI crawler is blocked in robots.txt, which is silent and common. Second, recency, your brand, or its current name, postdates the model's training data and it has no live retrieval for that query. Third, corroboration, everything an engine could say about you exists only on your own site, and engines prefer claims they can verify somewhere else. Fourth, category language, you describe yourself with words nobody searches. Work through them in that order, because the first is free to fix and the last takes a rewrite. Cituna asks seven AI engines your buyers’ questions every day and records, engine by engine, whether you are named, at what position and which competitors appear instead, from $39 a month.
Why this happens
Absence and low ranking are different failures with different fixes, and conflating them wastes the most time. A brand that is mentioned third has a positioning problem. A brand that is never mentioned usually has a mechanical one, access, recency or corroboration, and no amount of better copy resolves a mechanical problem.
Corroboration is the cause teams find hardest to accept, because it is not about quality. An engine assembling an answer weighs whether a claim appears in more than one place. A genuinely excellent product described only by its own marketing has one source, and one source is treated as an assertion rather than a fact.
What to do about it
Fetch your own robots.txt and check it against the named agents: GPTBot and OAI-SearchBot, PerplexityBot, ClaudeBot and Claude-User, Google-Extended. A rule written for Googlebot frequently catches these too.
Search for your brand name plus your category on the open web. If the only results are your own properties, corroboration is your binding constraint.
Test the words buyers use rather than the words you use. Ask an engine the question in a customer's language and see whether your category even matches.
Where Cituna fits
Cituna works through these four causes in order across all seven engines daily from $39, and separates “absent” from “mentioned but outranked”, which matters because they have different fixes. It also joins the result to Google Search Console, so you can see whether a brand that is missing from AI answers is still earning search clicks, or neither.
Then it does the work: it generates the fix for each gap, its AutoSEO writes and publishes the articles that answer the questions you are missing, and Claude or any other AI agent can work through the results over MCP.
