How to choose the best out of home advertising tools for UK buying

What to take away

Out of home advertising best tools are the software and platforms that plan, buy, verify or report on billboard and digital screen campaigns. For a UK buyer, a tool earns a place on the shortlist if it covers at least one of four jobs:

No product covers all four well. Apply these criteria, then pilot one campaign before committing to an annual licence.

Planning and audience tools

Start with planning. Route is the UK currency for out of home audience measurement. It uses travel data to estimate exposure across roadside, rail, bus, underground and retail inventory. A planning tool that cannot ingest Route data is a weak fit for classic billboard buying.

Other data sources include CACI's Acorn segments and Experian Mosaic. Ask vendors whether segments come from observed movement or modelled assumptions. That distinction matters at client sign-off. For how planning, buying and verification fit together, see the out of home advertising tools and supplier guide for 2027.

Programmatic buying platforms

Programmatic digital out of home platforms buy screen impressions through automated auctions. VIOOH is a supply-side platform launched by JCDecaux in 2018. It connects UK screen owners to demand-side platforms such as DV360 and The Trade Desk. Hivestack by Perion offers an SSP, DSP and ad server. Perion acquired Hivestack in 2023.

Broadsign provides software for screen owners and a programmatic arm called Broadsign Reach. Place Exchange is another exchange that links media owners with major DSPs. The Back to Basics Guide to Programmatic from IAB UK explains the mechanics. Check which screen networks are genuinely connected, what targeting signals are allowed, and how frequency is capped.

Verification and measurement tools

Verification tools check whether a campaign delivered what was bought. Seedooh is an independent verification platform used for out of home. It provides proof of play and campaign reports. Broadsign also offers reporting for digital screens. For classic billboards, site inspection records and photographic evidence remain common.

Ask for the methodology behind any impression number. If a vendor cannot explain how a play was counted, treat the figure as indicative.

ISBA's Agency management media guidance sets out how advertisers should govern agency relationships, including reporting and audit expectations. The training and events programme run by the Advertising Standards Authority covers advertising rules, including sessions relevant to out of home creative. Buyers who know the code catch compliance problems before a site goes live.

Creative delivery tools

Creative delivery tools manage format specs, dynamic content and compliance. Liveposter, a UK platform for dynamic digital out of home, helps brands schedule and deliver copy to screen networks.

OpenLoop by Grand Visual is another tool for dynamic creative. It connects data feeds to digital screens. Check whether the tool supports the formats you buy. A creative tool that cannot produce a proof of play file will add work later.

Procurement and contract checks

Procurement is where tool choice becomes a commercial decision. Compare licence models: per campaign, per seat or a percentage of media spend. A tool priced as a percentage of spend can look cheap on a small test and expensive on a national buy.

Check data ownership. If audience data sits with the vendor, can you export it when the contract ends? Ask about notice periods and whether unused campaign credits roll over. Those terms matter more than a feature list.

Implementation checklist

Once a tool is chosen, the work shifts to configuring it. The out of home advertising tool implementation guide covers setup, data feeds and team roles. Budget for training as well as licence cost: a team paying £400 a month for planning software may need several days of onboarding.

Common questions

Do I need separate tools for classic and digital out of home?

Often yes. Classic planning relies on Route and site data, while digital buying runs through platforms such as VIOOH or Hivestack. Some suites cover both, but verify coverage rather than assuming.

How many tools should a small media team run?

Two or three is usually workable: one planning tool, one buying platform and one verification method. More adds licence cost and reconciliation work without improving decisions.

What should I check before renewing a licence?

Review delivery against the objectives, the quality of reporting and whether the vendor added the regions you need. If usage is low, renegotiate seats rather than renewing the same tier.
