Extend Brand Recognition Across South Wales With Targeted Cardiff Advertising.
One Day Agency helps brands reach Cardiff audiences and increase city-wide visibility through out of home advertising campaigns.
The capital city of Wales is a lively, modern and dynamic place for brands to advertise. With a population of over 380,000, it's bolstered by tens of thousands of visitors and commuters heading into Cardiff every day.
As a port city built around iron, steel and coal, Cardiff has transformed into a service-sector-focused economy with a growing tourism market. Its iconic landmarks and high-footfall environments make Cardiff the perfect setting for ambitious brands to display their graphics and messaging.
Why Advertise in Cardiff?
Cardiff has a diverse, multicultural community and visitor profile. Standout locations like Principality Stadium, Cardiff Castle, the Pierhead Building and Llandaff Cathedral attract large numbers of visitors – alongside tens of thousands of students based at the city's three universities. Principality Stadium alone welcomes an average of 1.3 million visitors per year, with a capacity of 74,500.
Recent investments in regeneration have seen historical landmarks contrast with a vibrant shopping district, including St David's Centre – one of the biggest retail complexes in the UK.
Targeted campaigns around these high-profile locations improves the reach of your brand advertising. You can secure premium promotional spaces for billboards and digital screens around the Wales Millennium Centre, close to the Welsh Parliament and around the contemporary Cardiff Bay waterfront.

Frequently Asked Questions.
-
There isn't one single marketing approach that fits every brand. The first step is to speak with our team to discuss your business model, the types of consumers you want to engage with and key details like budgets, timings and any specific parameters that will influence the right campaign structure.
Outdoor advertising can reach as much as 98% of the UK adult population each week, while public transport advertising in Cardiff can provide exposure to vast visitor audiences. We work closely with brands to select the perfect marketing mix, whether you're looking for bus shelter displays, roadside billboards or digital retail advertising space.
-
Just as each campaign should be designed and deployed based on your branding and requirements, there are several key locations and high-demand display points to consider, depending on your target audience and messaging.
Static billboards and bus route advertising around heavily used routes – including Newport Road, Penarth Road, Churchill Way and North Road – can display ads to the largest possible viewer groups.
That said, digital billboard screens and interactive displays around Cardiff University and student hotspots may be equally impactful for brands with a younger target audience.
-
Each campaign we work on is created in partnership with our client. We support both smaller start-ups looking to disrupt an established market and larger corporations, charities and public-sector organisations with important messaging to share.
There isn't a fixed billboard advertising price – it varies based on the creative assistance needed, the duration of your campaign and the number of billboards required.
Get in touch anytime and we'll be happy to provide a tailored quote.
-
Cardiff offers strong reach at competitive prices compared to larger UK cities like London, Manchester or Birmingham. Its compact city centre means high footfall is concentrated in a smaller area, which can make OOH campaigns more cost-effective.
It's also the economic and cultural hub of South Wales, so a Cardiff campaign can serve as a gateway to the wider Welsh market. For brands testing regional campaigns before a national rollout, Cardiff is an ideal starting point.
-
Yes – and it's one of the most effective approaches. Pairing outdoor advertising with targeted digital campaigns creates multiple touchpoints with the same audience. For example, someone might see your billboard on their commute and then encounter a retargeted ad on their phone later that day.
One Day specialises in cross-channel campaigns that bring together OOH, digital and social media to maximise reach and return on investment.
