Everything you need to know about how Out-of-Home (OOH) advertising gets results

What is Out-of-Home advertising?

Out-of-Home (OOH) advertising is a term used to describe any advertising that reaches audiences in public spaces, outside of their homes. 

This includes billboards, bus shelters, train stations, airports, shopping centres, and other high-traffic environments - meaning Out-of-Home advertising campaigns are visible across every part of an audience's journey. As the leading OOH publisher, JCDecaux's premium network of sites acts as a showcase for brands to connect with audiences at the most impactful locations across the UK.

Pentland's results clearly demonstrate the impact of adding Out Of Home advertising to the media mix. We saw saw marked uplifts in awareness and consideration in London and Manchester where OOH was live. Together, these results show how targeted OOH advertising can both stimulate online demand and strengthen brand metrics across the funnel.

OOH advertising is flexible and targeted

 

What is Digital Out-of-Home (DOOH)? 

DOOH is any Out-of-Home advertising that is shown on a digital screen instead of a traditional paper poster or billboard. Combined with the big reach of standard OOH, Digital Out-of-Home gives way to capabilities such as ad campaigns with subtle motion and video, programmatic buying, and precise measurement of campaigns.

What are the benefits of Digital Out-of-Home?

Through digital scheduling, advertisers are able to target specific areas, times and contexts with Out-of-Home. Layered audience data can be integrated directly with the activation of DOOH campaigns to reach specific segments that are fine-tuned to whomever the advertiser wants to reach. This digital activity can therefore be optimised to see further Return on Investment (ROI) from OOH campaigns.

What is Programmatic DOOH?

By virtue of being a digital channel, DOOH can also be bought programmatically. Similar to paid social and search campaigns, this is a method for advertisers to buy OOH ad space through an automated online platform, which allows for an even greater level of flexibility, including:

  • Dynamic and reactive creatives that respond to triggers such as time of day, location, sporting event scores, ,weather, audience movement, and retail footfall.
  • Real-time measurement and optimisation of DOOH campaigns while they are running
  • The ability for advertisers to pause their campaign with the click of a button

Programmatic digital Out-of-Home played an instrumental role in this omnichannel campaign...we reached a precise audience with contextually relevant ads across the best-performing OOH environments.

OOH is a trusted advertising channel

Constantly seen in the public eye, Out-of-Home advertising is part of our daily lives in the environments that we travel through every day, and has been for decades.

This means that as a channel, OOH is highly trusted and well regarded by its audience; the ‘P² + C = 6’ report reveals that the combination of public and private marketing, brings a ‘halo effect’, thanks to trust in the public screen.

This trust is also transferred to the brands that launch OOH campaigns. From 'The Moment for Trust' insight, we know that 81% of people say that trust in a brand influences their purchase choice.

Brand trust is today’s most important consumer relationship, especially when it comes to a financial product like a pension. It not only convinces customers to sign up or buy a product, but it is also the key ingredient to brand retention…. certain marketing channels, such as Out-of-Home, lend themselves better to build trust because consumers see it as brands making a public commitment. It creates brand fame and familiarity - once you've seen us on a billboard or TV screen, you're more likely to click on a targeted Social Media ad from us and move all your pensions across. That’s why at Pension Bee, we’re increasingly optimising our marketing campaigns by including a mixture of public and private media, with channels like Out-of-Home used to build trust, broaden who we reach, and ultimately, help accelerate our customer growth.

What are the benefits of Out-of-Home?

Out-of-home advertising is one of the most effective ways to build brands at scale and drive results from digital channels. In the UK, Out-of-Home reaches over 97% of the population each week, giving brands unrivalled national coverage and cultural visibility. Digital Out-of-Home alone delivers 4.8 billion impressions weekly, providing the reach and effectiveness needed to grow brand awareness, consideration and sales.

Out-of-Home is now a powerful brand-building and activation channel used by many of the world’s best brands. Thanks to new digital capabilities and investment in high-quality digital screens backed by data, advertisers can:

  • Target the right audience at the right moment – use data to focus spend where and when it has the most impact, based on location, time of day, audience behaviour or context.
  • Increase flexibility and responsiveness – update creative in near real time, run dynamic campaigns and optimise messaging across different environments and formats.
  • Enhance campaign effectiveness across channels – Out-of-home makes other digital marketing channels like paid search and social work harder, boosting recall, click-through and conversion when people later see your brand online. JCDecaux UK’s “Two-Screen Effect” research shows how the combination of Out-of-Home and mobile delivers stronger performance than either channel alone.
How effective are billboards compared to digital advertising?

Rather than competing, billboards and online digital channels work best together. Out-of-home and billboards can prime audiences in the real world, so that paid search, social and online video perform better when they later see or seek out your brand on their devices. This combination improves ad recall, click-through rates and conversion, making both channels more efficient and effective.

When people encounter a bold, creative billboard on their daily commute, it creates instant impact and builds trust in a way that an online ad often cannot. That’s why billboard advertising works so well as a foundation for your wider media mix.

Key reasons why billboard advertising and Out-of-home works:

  • Guaranteed visibility: Billboards and Out-of-Home occupy prominent, real world locations that people can’t scroll past or block.
  • Mass reach and repetition: Out-of-home advertising delivers continuous exposure to large audiences, reinforcing brand messages over time.
  • Brand fame and credibility: Appearing on a high-profile billboard signals scale and confidence, helping brands stand out from purely online competitors.
  • Synergy with digital: Billboards drive search queries, social engagement and website visits, amplifying the ROI of digital campaigns.
