Performance marketing only fishes in 5% of your future market. The other 95% pick the brand they already remember. The largest peer-reviewed advertising effectiveness dataset on earth has been saying this for forty years.
Most founders have never heard of it.
First Class Business | May 2026
In 2013, Les Binet and Peter Field analyzed 996 advertising effectiveness case studies from the IPA Databank, covering 700 brands across 83 sectors over more than 30 years. Their finding: the most effective campaigns allocated approximately 60% of budget to brand building and 40% to sales activation. Their 2019 research with the LinkedIn B2B Institute refined the ratio for B2B to roughly 46/54, accounting for longer sales cycles.
In no sector they analyzed does pure-performance allocation outperform balanced. The WARC Multiplier Effect study (January 2025, in partnership with Analytic Partners, BERA.ai, Prophet, and System1) added the cost: brands moving from performance-only to mixed see a median 90% ROI uplift. Brands moving the other way lose 40%.
"You can't just use performance techniques to drive growth. It's too expensive and it doesn't work."Peter Field, IPA Effectiveness Research
Three things almost every founder believes about paid advertising. All three are contradicted by the data the industry has been collecting since 1980.
Professor John Dawes of the Ehrenberg-Bass Institute introduced a concept in 2021 that should be on the wall of every founder making decisions about ad spend. At any given moment, only about 5% of your potential buyers are actively in the market for what you sell. The other 95% are not researching, not comparing, not ready to buy. They may enter the market next month, next quarter, or three years from now. But right now, they are not.
If your entire budget is structured to convert the 5%, you are fighting over a thin slice of your future revenue. When the 95% eventually enter the market, they choose from the brands they already remember. Not the cheapest ad at the right moment. The brand they have built mental availability with over time.
Two ways to look at the same problem. The first accordion is how the math changes by where the business actually is. The second is how the budget gets allocated inside a properly built campaign. Both are practitioner consensus on small-business paid-media execution. The 60/40 IPA allocation principle sits above both as the broader effectiveness frame.
Budget changes what a campaign can structurally accomplish. The four ranges below are not hard cutoffs. They are the points where what's possible shifts.
| Business Stage | Honest Play | What This Actually Looks Like |
|---|---|---|
| $0 - $500/mo paid | Creative-test budget, not a full program | Strong creative against the right audience can absolutely produce outsized results at this spend. Concentrate it: one cold-audience test against your best creative, or remarketing against your warmest list. Statistical reliability is thin. Outsized wins are real and worth pursuing if creative and offer are sharp. |
| $500 - $2,000/mo | Tight focus, remarketing-heavy | Enough volume to start learning, not enough to run a balanced program. Weight toward remarketing for the early conversion data. Run one cold campaign with one or two creative variants. Plateau risk is real but not inevitable. Strong creative breaks through. |
| $2,000 - $10,000/mo | Full structure becomes possible | Room for the 70/20/10 split (remarketing, cold audience, creative testing). Brand-side measurement (branded search lift, direct traffic, video completion) starts to clear noise over 60-90 days. This is where founders start seeing both halves of the compound effect. |
| $10,000+/mo | Both halves at scale | Approach the IPA ratios: roughly 50/50 for B2B, 60/40 for B2C. Performance captures the in-market 5%. Brand work builds mental availability for the 95%. The two compound. This is the budget tier the IPA dataset was largely measuring. |
The strongest variable at any tier is creative quality and offer strength. Google's internal data attributes 70-80% of campaign effectiveness to creative. Budget tier sets the ceiling. Creative and offer determine where inside that ceiling the campaign actually lands.
The practical floor for a real testing program is $1,500 to $3,000 per month. Below that, impression volume is too thin to learn anything statistically meaningful and the platform's learning loop cannot optimize. Once a campaign is over that floor, the allocation inside it matters.
| Budget Allocation | Where It Goes | What It's Doing |
|---|---|---|
| 70% Remarketing | Site visitors, email subscribers, CRM contacts, video viewers | Lowest-CAC traffic in the account. Builds the conversion data the platform needs to optimize cold campaigns later. This is where attributable returns come from in the first 60 days. |
| 20% Cold Audience | One campaign on a custom intent or in-market segment matching the ICP | The brand half at small scale. Judge by CPV, completion rate, and view-through for the first 60 days, not by direct conversions. This is the audience-building investment. |
| 10% Creative Testing | Multiple thumbnails, multiple hooks, multiple lengths | Without rotation, the account stagnates on whatever shipped first. Creative quality drives 70-80% of campaign effectiveness per Google's internal data. |
What has to be built before the spend goes live: conversion tracking that actually fires, first-party audience lists uploaded and segmented, two or three creative assets in rotation, a landing page that matches the ad's promise, a specific offer that earns the click, a weekly review rhythm, and a written success threshold for 30, 60, and 90 days. Without these seven foundations, the campaign launches against thin air regardless of how much is spent.
The seven foundations above are the difference between spend that compounds and spend that bleeds. The Pre-Flight Checklist walks through each one in order, so the campaign launches against the right setup, not against thin air.
Two camps in marketing talk past each other constantly. Most founders only ever hear from one. Knowing both is what makes the difference between an opinion and a decision.
The performance camp (paid-media practitioners) knows how to run campaigns inside the platforms. They are correct about how. Their commercial offering biases them toward performance as the whole strategy.
The effectiveness camp (Binet, Field, Sharp, Dawes, Ritson, System1) is correct about long-term growth dynamics. Their research is largely from brands large enough to fund both halves at scale, which leaves operators at smaller budgets without execution guidance.
Both halves matter. Performance captures the demand that exists today. Brand work, in whatever form a founder can fund, builds the demand that will exist. The right mix depends on the business, the offer, and the founder.
