The 60/40 rule comes to OOH planning

A media-planning argument that keeps resurfacing got a fresh OOH airing this week: the 60/40 rule. Drawn from Les Binet and Peter Field’s work on the IPA Effectiveness Databank, it says the long-run-optimal split is roughly 60% of budget to brand-building and 40% to activation — because “brand building creates future demand; performance marketing harvests current demand” (via OOH Today, 23 July 2026). The problem the piece names: most brands have inverted it to about 80/20 in favour of performance, hit diminishing returns as performance channels saturate, and now need somewhere to rebuild brand. The pitch is that OOH is that somewhere — a brand-building medium that, unlike a TV spot, also throws off foot-traffic, web-traffic and device-ID signal you can measure. It’s an old framework, but the reason it’s back is new: the performance well is running dry.

The argument

60/40 — the long-run-optimal split is ~60% brand-building / 40% activation (Binet & Field, IPA Effectiveness Databank) (via OOH Today, 23 Jul 2026 — established framework).
Most brands have inverted it to ~80/20 toward performance, driving channel saturation and declining returns (OOH Today — directional).
OOH is cast as the brand-builder that also performs — building share of voice while generating foot-traffic, web-traffic, device-ID and attribution signal (OOH Today — directional).
Case cited: DTC brand Saatva hit a performance ceiling by 2017, added OOH to rebalance the mix, and it became a top-performing channel on the way to “$100M+ omnichannel” (OOH Today — brand-reported case, directional).
The read: the 60/40 case is really an argument for where fresh reach lives — and for beauty, that’s the screen at the top of the funnel (BDOOH analysis).

What happened

Nothing “happened” in the news sense — this is a framework, not an event — but it’s worth flagging because the 60/40 argument is quietly becoming the standard way OOH sells itself into over-optimised, performance-heavy plans. The logic holds together: if you’ve pushed 80% of budget into channels that harvest existing demand, you eventually run out of demand to harvest, and returns fall. Rebuilding the top of the funnel means brand-building media — and OOH’s pitch is that it’s a rare brand medium that also leaves a measurable trail (a scanned QR, a store visit, a retargetable device ID). The Saatva anecdote is a single brand-told story, not proof, but it illustrates the shape: activation ceiling → add reach → mix unlocks.

What it means for beauty

Beauty is a brand category, so the 60/40 logic hits hardest here. People buy beauty on desire, identity and reputation as much as price — the definition of brand-led demand. That makes the media-mix decision a brand-building decision first, and screens the natural home for the 60 side. It’s also why OOH amplifies digital instead of cannibalising it: the screen builds the demand the performance channels later harvest.
The medium’s strength is the 60, but its proof is the 40. OOH earns its place in the brand budget, yet the reason planners will actually move money is the measurable trail — attention as the currency on the brand side, and QR and O2O attribution plus honest effectiveness measurement on the activation side. A beauty screen that only claims “impressions” sells the 60 and forfeits the 40.
Don’t over-correct a beauty plan into pure activation. The trap the piece describes — 80% performance, saturating returns — is exactly the mistake a foot-traffic-obsessed beauty brand makes when it treats screens as coupon dispensers. Our beauty ad-spend and the media mix work is the counterweight: build the brand where attention is cheap, then harvest.

The caveat that keeps us honest

60/40 is a rule of thumb from aggregate effectiveness data, not a law — Binet & Field themselves stress it varies by category, brand maturity and objective, and the “80/20 inversion” and Saatva outcome are directional, brand-told illustrations, not audited benchmarks. Nothing here is a beauty-specific figure; we’re reading an established planning framework across to our thesis, not inventing a number. The durable, honest point is one of role, not ratio: in a world where performance channels are saturating, OOH’s job is to rebuild the top of the funnel — and beauty, being brand-led, is the category where that job pays back fastest. The exact split is yours to test.
