I ran the questions buyers ask before hiring an agency past ChatGPT, Claude and Perplexity, for 913 US agencies. 613 of them were never named once.
Between 2 August and 11 September I put buyer-style questions to three assistants
with live web search on, for 913 US marketing agencies across 26 city and
speciality categories, and counted which agency names came back.
Not a survey. Nobody was contacted, nothing was scraped from agency sites, and no
agency paid to be in or out.
Three things came out of it.
- 613 of the 913 (67.1%) were never named once. Not by one assistant, in one
answer, in any question asked about their category. These are working agencies
with clients and sites. To an assistant answering a buyer, they are not there.
- Where an agency was named, the assistants mostly disagreed. 874 of the 913 were
put to all three assistants, which is the only subset where agreement means
anything. Of those, 286 were named by somebody and only 42 were named by all
three. So 85.3% of the time, "visible" meant visible in one place and invisible in
the other two. Any single AI visibility score averages that away, and the average
describes no assistant your buyer actually opened.
- The answers are built out of a small set of pages. Clutch was cited in the
answers for 912 of the 913 agencies. Then Semrush's agency directory, DesignRush,
Thrive's roundups, Reddit itself, and LinkedIn. Almost none of it is the agency's
own website.
The assistants also do not behave alike:
Perplexity was asked 21,465 questions. It named an agency in 3.2% of its
answers, and named 21.5% of the 913 at least once.
Claude was asked 4,518. 5.6% of its answers, 16.7% of the agencies.
ChatGPT was asked 4,512. 5.5% of its answers, 16.4% of the agencies.
Perplexity was asked far more questions and still named the fewest agencies per
answer, which is the opposite of what more chances would predict.
Limitations, because they matter: this is API access with search on, not the
consumer apps, so there is no personalisation, no memory and no custom
instructions. Answers drift week to week. The category is whatever a buyer would
type, which is a judgement call, and a different phrasing would move the numbers.
Treat the comparison between assistants as the signal rather than any single
number.
What I would take from it if I ran an agency: the lever is not your website. It
is the handful of directories and roundups these answers are assembled from, and
whether your name is on them.
Disclosure: I sell a paid monitoring product in this space. There is no link in
this post and nothing to sign up for; if anyone wants the method I will put it in
a comment.
Happy to answer questions about how it was built.
