Advertise in Cardiff

Billboards are a great way to elevate your brand above the crowds and get your message to huge audiences – especially roadside or public transport billboards in popular visitor hotspots.

We offer a complete range of billboard advertising solutions, including full-size, high-profile public space billboards and more precision-targeted placements in areas most frequented by your target demographic.

Displaying your brand messaging across Cardiff's busy public transport network lets you select specific routes, vehicles or platforms that align with your ideal consumer persona. This includes the South Wales Metro – a £1 billion investment in electrified rail across the region, with services running up to every five minutes on key routes.

The volume of cycling routes, trains and bus services alongside private hire cabs gives businesses countless ways to get their brand in front of the right people. You can choose tactical placements and timings to align with events, festivals and peak visitor periods.

Digital billboards are the advertising format of the moment. With over 21 million visitors a year, Cardiff offers massive reach – and digital formats, from full-size, visually immersive billboards to data-backed campaigns on smaller transport screens, help brands generate excitement, engagement and entertainment.

Fast-growth and innovative brands use digital OOH to reach younger audiences, flex their promotional offers based on the weather or time, and improve brand recall through repeat exposure.

The large numbers of students living and travelling to and from Cardiff every day create a strong brand marketing opportunity. There are three city-based universities and campuses across the region, and Cardiff University alone has 33,000 enrolled students.

Cardiff Metropolitan University was awarded Top UK University for Sustainability in 2022, further attracting students and businesses keen to tap into the appetite for eco-friendly brand messaging.

Targeted digital, social and paid campaigns can reinforce the effects of your OOH and billboard advertising. Using detailed research, we ensure each element of your cross-channel campaign boosts exposure, brand awareness and credibility with your chosen viewer groups.

One Day often works with businesses looking to launch campaigns featuring several mediums and methods of advertising. This approach boosts returns on advertising investments and pulls everything together to achieve your brand objectives.

Cardiff hosts major events throughout the year – from Six Nations rugby at Principality Stadium to music festivals and Christmas markets. These events draw hundreds of thousands of additional visitors to the city, creating short-term spikes in footfall and attention.

Event-based advertising lets brands align their campaigns with moments of high visibility. Whether it's matchday billboards, festival sponsorship or seasonal digital screens, timing your campaign around key Cardiff events can dramatically increase reach and engagement.

Cardiff's retail core – centred around St David's Centre, Queen Street and the Hayes – attracts millions of shoppers each year. Advertising within and around these areas puts your brand directly in front of consumers who are already in a buying mindset.

Formats include digital screens inside shopping centres, window displays, escalator wraps and proximity-targeted mobile ads. For brands selling consumer products, this is one of the most direct routes to driving footfall and purchases.
