Clear Channel Outdoor Expands RADAR Measurement With LiveRamp and TransUnion

24 September 2026 | New York, United States

Clear Channel Outdoor has announced an expansion of its RADAR data platform, connecting outdoor audience, exposure and delivery data with measurement tools from LiveRamp and TransUnion. The 24 September announcement focuses on assessing OOH within a broader media plan.

What the announcement includes

The company release identifies a partnership with LiveRamp’s Cross-Media Intelligence and integrations with TransUnion’s marketing mix modelling (MMM) and multi-touch attribution (MTA) solutions.

Clear Channel says the LiveRamp connection supports analysis and deduplication of outdoor exposure alongside other channels. It describes granular delivery data as an input to TransUnion’s MMM, with exposure data resolved against identity for MTA.

These are announced measurement capabilities. The release does not publish a quantified campaign lift, advertiser ROI comparison or independent validation study. The company’s site also notes that some RADAR solutions may not be available in every CCO market.

Why the input data matters

BillboardGuide’s analysis: A measurement integration is useful when it helps an advertiser answer a decision that was previously difficult to assess. That might concern media allocation, campaign contribution or audience overlap. The first step is to define that decision and then establish which data the proposed method needs.

Ask whether the outdoor input represents expenditure, scheduled delivery, recorded plays or estimated exposure. Those fields describe different parts of a campaign. A model should make their role clear rather than treating every input as equivalent evidence of audience contact.

Our OOH measurement analysis explains why volume should be considered alongside the quality and conditions of a placement.

Shared reporting needs shared definitions

Putting channels into one reporting system can help teams compare a campaign, but the definitions behind each number remain important. Advertisers should request an explanation of how outdoor exposure is estimated, how overlap is handled and which observations are eligible for analysis.

A useful measurement brief identifies the geography, campaign dates, outcome window and scope of the media plan. It also makes limitations visible. If part of the inventory or audience cannot be represented, the report should explain the effect on interpretation.

These questions should be agreed before launch so the team knows what the final analysis can establish.

Keep attribution and business impact distinct

The appearance of an outdoor touchpoint in a customer journey does not, by itself, demonstrate that the touchpoint caused the subsequent purchase. Buyers should ask how a method handles other influences and what evidence supports any claim about incremental impact.

Likewise, an aggregate result should not automatically be used to rank individual billboard faces. The unit of analysis matters: a portfolio, a market and a single placement require different evidence.

For media planning, review locations and creative alongside the reporting plan. BillboardGuide’s digital billboard guide provides context for assessing the physical inventory, while the creative checklist supports artwork review.

Questions for an advertiser considering the integrations

Ask which markets and inventory are eligible, what services and fees are required, which data will be supplied, and what reporting the advertiser receives. Agree on the business outcome to evaluate and the timetable for analysis.

The announcement creates another route for outdoor data to enter media evaluation. Its practical value will be clearer when buyers can assess the method, coverage and resulting evidence for their own campaigns.
