LONDON - IndianaStop -- LEEDS/LONDON - Loud! OOH has published the results of its York Street billboard campaign, and the numbers point somewhere the agency did not expect when it booked the sites.

In June 2026 the independent out of home agency put two 48-sheet hoardings side by side on York Street in Leeds city centre. The first carried a real customer quote of £650. The second showed the Loud! OOH rate for the same site: £325. No competitor was named. The gap between the two numbers was the whole message.

Two weeks on, the campaign had delivered:

• 188% uplift in new website traffic
• 155.9% increase in LinkedIn post views
• 61.1% growth in LinkedIn followers
• 8 press placements across 6 publications, including Ads of the World, MSN, Prolific North and a guest post on The Drum.

Two client campaigns confirmed for August, with enquiries still landing "We put our own money on the same media we buy for clients, and it outperformed every pitch deck we have ever sent," said Jamie Roberts, founder of Loud! OOH. "Small businesses do not distrust billboards. They distrust not knowing what one costs until they have sat through a discovery call."

The second payoff was not human

The billboards came down. The pricing page did not. Since May, enquiries from people who found the agency through AI tools have risen 266%. Roberts links the two directly. The same published numbers that made the billboards work are the numbers AI systems can actually quote back to someone asking what a billboard costs.

"A hidden rate card is invisible to a machine," said Roberts. "If your prices sit behind a contact form, there is nothing for an AI tool to cite. We published everything for honesty reasons. It turned out to be the best technical SEO decision I have made in twenty years in advertising."

The agency now treats being quotable as a channel in its own right, and says it is the first UK out of home agency to build its site around AI answer engines rather than Google rankings.

The numbers behind both

Loud! OOH publishes every rate it charges. 48-sheet billboard advertising costs start at £325 in regional cities and £650 in London. 6-sheets run from £300. Bus rear panels start at £60 per panel per two week period. No forms, no discovery calls, no markup.
