Advertising Agency

An advertising agency that makes ads people remember and act on

Updated October 2026.

Prohibition is a Leeds advertising agency. We create and run campaigns across paid social, search, TV, out of home and video, and we join them up with PR so every pound works harder. Our Goldsmiths Christmas brand film reached 1.7 million YouTube views and drove more than £1M in sales from paid media, with a multichannel return of £7.94 for every pound.

What does an advertising agency do?

An advertising agency plans, creates and places paid campaigns that reach the right people and get them to act. We do all three in-house: strategy and media planning, creative and production, then buying, optimising and reporting.

Which advertising channels do we use?

How does advertising help PR?

PR earns trust and coverage; advertising guarantees the right people see it. When both tell the same story, each makes the other more effective. Interflora’s Behind the Blooms films told real customer stories and ran as paid social, reaching more than 3.5 million people at a penny a click.

Advertising and branding work together

Your brand is the look, voice and promise; advertising is how you put it in front of people. We keep both consistent through our branding and design teams.

How do we plan an advertising campaign?

We start with the business goal: awareness, footfall, leads or sales. Then we pick the audience, the message and the channels, and agree how we will measure success before any money is spent.

We test creative early, move budget to what works and report in plain English. For The Property Sourcing Company, paid social produced 94 leads in month one, five times cheaper than Google Ads.

Advertising for ecommerce

Conversion ads, retargeting and social commerce turn interest into sales. For MolarClean we set up TikTok Shop and conversion ads that returned ad spend from month one.

What creative do we make for advertising?

Graphic design

  • Digital display
  • Event promotion

Video

Everything is made by our in-house designers, editors and producers, so changes are quick and the brand stays consistent.

Build a brand people recognise

Consistent colours, type and tone across every ad make each one more memorable and cheaper to run over time.

Authentic advertising builds trust

Real customers and real employees beat stock actors. Interflora’s real customer films and EQUANS’ employee-led videos both outperformed polished alternatives.

Advertising and reputation

Ads amplify whatever people already think of you. We check reviews, coverage and sentiment first, so spend is not wasted.

Drive sales, not just awareness

We track every campaign to the result that matters, using pixels, UTM links and GA4, and optimise towards it weekly.

Paid reach for earned stories

When a PR story lands, paid social puts it in front of buyers who missed the coverage.

Launch new products

From teasers to launch-day ads, we plan the sequence that builds demand. See our product launch PR.

Video advertising

Video is the strongest ad format on most platforms. We script, film and cut versions for each one.

How much does advertising cost?

It depends on your media budget, the channels, how much creative and production you need, the number of markets and the length of the campaign. We give you a written proposal after a first call.
