GEO / AEO philosophy
Bubblegum Search treats AI visibility as a reputation problem on other people's websites. It tracks a client's buyer questions across ChatGPT, Google AI Overviews, and other AI platforms, finds the third-party pages those answers draw on, and runs outreach to get the client mentioned on them. Agencies can buy the same work white-label.
The agency argues that mentions have to be earned on third-party pages and that results build over time, so it does not credit one placement with one result. "Authority has to exist beyond your own website," writes Matt Cayless, who founded the agency. Its own SourceSignal report for September 27 to October 26, 2026 shows it mentioned in 12.3% of 4,346 AI answers across 39 buyer questions, with 11 "best agency" lists live. Bubblegum Search publishes these figures itself, from a platform its founder co-founded.

Innovation
Bubblegum Search reports against SourceSignal.ai, a tracking platform its founder co-founded. SourceSignal.ai asks each tracked question again every week across up to nine AI engines and grades the pages AI cites. The agency's packages promise a minimum number of relevant brand mentions each month, 1, 2, or 4, and state that rankings and recommendations in AI answers cannot be guaranteed.
Pricing
Bubblegum publishes its prices in pounds, all plus UK VAT. At about $1.33 to the pound, AI SEO packages run about $730, $1,330, and $2,400 a month for 1, 2, or 4 guaranteed brand mentions, digital PR campaigns start at about $1,060, and integrated digital PR and SEO starts at about $2,400 a month. There is no setup fee and no long-term contract, and one calendar month's notice cancels.
Review Excerpts
“Great work from Matt, Georgia and the team at Bubblegum. We ran a digital PR campaign that picked up multiple backlinks from 85+ domain authority. The first campaign idea didn't work as well as hoped, so they quickly pivoted and the results were great.”
“They were priced about half of what I had paid in the past, but they also had lower guarantees and I was ok with that.”
“Matt and the team were super helpful and took the time to understand our goals. The advice they provided was clear and actionable with strong results.”
