OOH vs Digital Equivalence Planner
This planner calculates the equivalent digital media budget needed to match the reach and frequency of a proposed OOH campaign, and vice versa, enabling honest cross-media comparisons during planning. It is designed for integrated media planners and marketing directors who need to defend or challenge OOH budget allocations relative to digital alternatives using a common audience currency. The tool models the comparison under multiple equivalence factors so you can present a range rather than a single contested figure.

Frequently asked questions
Is OOH advertising more or less expensive than digital?
On a raw CPM basis, OOH often appears less expensive than premium digital formats like CTV or digital video. However, OOH reaches audiences in physical space without the ability to target by interest, intent, or demographic at the individual level, so raw CPM comparisons can be misleading. OOH's strength is cost-efficient mass reach in specific geographies; digital's strength is audience targeting and direct attribution. Most integrated plans use both for different jobs rather than treating them as direct substitutes.
Can OOH advertising drive digital campaign performance?
Research from the OAAA and independent studies shows that OOH exposure increases online search activity and improves digital campaign effectiveness when the two channels are running in the same market simultaneously. Consumers exposed to OOH ads are more likely to search for the brand online and more likely to respond to digital retargeting. This halo effect means that OOH's contribution to digital campaign performance is often undercounted when evaluating channels independently.
How do I include OOH in an integrated media plan?
OOH works best as a reach-builder in an integrated plan, covering the geographic footprint of a campaign and generating ambient brand exposure while other channels handle targeting and conversion. The planning sequence is to allocate OOH first for the market coverage it delivers, then layer digital channels on top to reach the same audience with targeted messages that can be clicked, attributed, and converted. Setting consistent audience definitions across channels makes cross-media planning more defensible.
