Two weeks ago we were top of our own UK B2B Tech PR AI Visibility Index, having climbed from 57th in a fortnight. This week we're 6th. A competitor published a single page, the AI assistants started reading it within days, and the order of the table changed around it.
It is the clearest evidence yet of how AI search works for B2B companies, because the same thing that lifted us has now lifted others.
Every week we ask six AI assistants the same 86 questions a buyer might ask when looking for a UK B2B tech PR agency, and we count which agencies they recommend. In week 3 Hotwire came first with 8.4% of the weighted share of mentions, followed by Clarity on 7.5%, Archetype on 6.9%, Wildfire on 6.7% and Brands2Life on 6.6%. We were 6th on 5.6%, down from 1st the week before.
The assistants still disagree about who leads. Hotwire comes first on ChatGPT and both of Google's AI search features, Clarity leads on Gemini, CCgroup on Perplexity and we still lead on Grok. On ChatGPT, which carries the most weight in the index, we're second.
Clarity has published a page called "The best B2B tech PR agencies in the UK in 2026". It gives a quick answer at the top, explains how the agencies were chosen and then lists eight agencies, each with a line on what it is best for. The assistants hadn't cited it once in our earlier runs, and this week they cited it in 95 answers.
Every agency on that list rose. Clarity moved from 10th to 2nd, Babel PR from 17th to 8th and Eskenzi PR from 48th to 11th, while Brands2Life and Wildfire climbed into the top five. Resonance isn't on the list, so the page did nothing for us, and the extra mentions it created for the other agencies pushed our share down.
Our own numbers barely moved. ChatGPT named us in 47 of its 83 answers, exactly as it did the week before, although the questions changed, with us dropping out of 13 and appearing in 13 new ones. Our category page was still the single most-cited page in the study, appearing in 109 answers, and in 23 ChatGPT answers the assistant read our page and Clarity's together and blended the two lists.
The page went from no citations to 95 in a single week, which is far too fast to be explained by links or authority built up over time. It worked because it matches the buyer's question almost word for word. Its title is the question people ask, it answers that question in the first sentence, and its structure is easy for an assistant to quote, with stated criteria, a numbered list and a clear date.
That is the same reason our own page lifted us from 57th to 1st. Assistants that search the web as they answer look for the page that answers the question most directly, and they pick it up within days. Our research on what AI reads before it recommends found that when a buyer asks about a category without naming a company, most of what the assistants cite comes from sources other than the company's own website.
There is. When we leave out answers that were reading our own website, we rose from 58th to 16th this week, our best result on that measure so far. Other sources are starting to mention us, and that kind of visibility is much harder for a single competitor page to displace.
We also added Firefly Communications to the table this week. It has a London office, the assistants named it often and it appears on Clarity's list, so it entered in 12th.
This week shows how fragile a position built on one page can be. Our response is the same advice we give clients. We're improving our own comparison page so that it answers the buyer's question as directly as Clarity's does, with stated criteria and a fair, complete list that includes our competitors. Alongside that, we're working to appear on the third-party lists and trade coverage that the assistants read, because those sources carry our name in places we don't control.
The research behind this is in our report on earned media in the age of AI answers, which looks at which publications the assistants cite when buyers are choosing a supplier.
