Key findings include:

  1. Current attribution methods underestimate radio advertising’s true performance effect by 92%:
    • Econometric modelling reveals how it takes 19 hours for the full effects of each radio spot to be realised.
    • Only 8% of a radio spot’s full effect is delivered in the first 20 minutes immediately following transmission.

  2. When its full impact is accurately captured, radio is proven to make a highly effective contribution to performance-led media campaigns.
    On average, across the campaigns measured in this study:
    • Radio advertising boosts daily web sessions by 9%
    • Radio uplifts web sessions twice as cost-efficiently as other ‘demand-generation’ media combined.

  3. Radio campaigns that deliver above-average performance efficiencies benefit from higher weekly reach & feature distinctive audio brand assets (used consistently across media/over time).

  4. Radio advertising’s indirect response effect augments results from pureplay digital response channels:
    • Boosting Organic Search volumes.
    • Increasing Paid Search impressions with improved conversion to referrals.
    • Uplifting response to Paid Social ads.

  5. Using more radio improves Performance Marketing efficiencies.
    • Increasing radio’s share of spend (by reallocating existing budgets from other media) enhances overall campaign performance at no extra cost.
    • The case studies in this report reveal how radio advertising delivers improved campaign effects even when allocated 50%+ share of total media budget.

  6. Radio additionally generates longer-term benefits for performance brands.
    • Beyond delivering a cost-efficient short-term boost to performance metrics, radio advertising also producespositive brand effects (for no additional cost) – which can help generate demand in the longer-term.
