A reader answered this morning’s avoid list with the question the list left out: does skipping off-site mentions belong on it, because it feels like the biggest miss in AI search right now? The question improves the list. My three tiers are sins of commission, failures you commit on your own site with your own hands. The hole in the list is a sin of omission, and it belongs to companies doing everything right: nobody, anywhere else on the web, mentions you.
Answers are assembled from corroboration
An answer engine builds its reply the way a careful stranger builds an opinion: it collects what several sources say and repeats what survives the comparison. A claim that lives on one domain is a claim by an interested party. The same claim carried by a trade publication, a local paper, a directory with standards, and three customers arguing in a forum thread becomes a fact the machine can use. The avoid list says the engines cite sources they already trust. Trust has an address book, and other people write the entries.
Twelve answers, zero mentions
This week I ran a baseline for a regional retailer with several stores under one parent company. Three questions a buyer would actually ask, put to four engines: ChatGPT, Perplexity, Gemini, and Google AI Mode. Twelve answers came back. The parent company was named in none of them. Its stores were named in answer after answer, near the top, because the web talks about the stores constantly: review sites rank them, map directories list them, customers recommend them by name in Reddit threads. The company that owns the stores, employs the people, and signs the leases exists in the answers only as an absence. Its own website is accurate, complete, and correctly built. The engines had every technical reason to crawl it and no social reason to name it.
Your site is testimony, and testimony is the weakest evidence
Every company website is testimony in its own case, and everyone in the proceeding knows it, including the machines. Buyers ask their friends instead; answer engines route around the interested party and quote the witnesses. The mentions that move an answer live on ground you do not control: editorial coverage you earned, directories that verify before they list, reviews written by customers with no reason to help you, forum threads where your name survives an argument. That ground accumulates in public, at the speed of other people’s interest. It cannot be renovated from your desk.
The refusal that changes nothing
Here is the uncomfortable arithmetic. A company can refuse every played-out tactic in tier one, ignore every charm in tier two, stay continents away from tier three, publish current first-hand material on a clean and honest site, and remain invisible in every answer that matters, because the entire program ran inside one domain. The avoid list keeps you from losing. Winning requires a second program, run in other people’s publications, directories, and threads. AI search measures your reputation where you are not the author.
Mentions are earned by being worth citing: original numbers nobody else has, expertise with a name attached, work that helps strangers solve the problem they typed into the machine. Do that work in the open, on the record, where the corroboration layer can find it. The engines are listening to the whole web. Make sure the whole web has something of yours to say.
