Minimum Viable Effect Guide for Media Planning

There's a threshold below which advertising produces no meaningful effect — not a weak effect, but effectively zero. Minimum viable effect is the point where exposure becomes memory, where reach becomes recognition, where a campaign crosses from noise into something that actually shifts behaviour.

This is a directional model based on media effectiveness research and channel benchmarks. Real-world outcomes depend on creative quality, targeting, market context, and many variables this tool can't account for.

Use it as a structured starting point for thinking — not a precise prediction.

Define your audience and goal

Enter your total addressable audience, your target reach percentage, and your campaign objective — brand awareness, demand capture, or full-funnel growth. Each goal requires a different minimum frequency to produce a genuine memory effect.

Set your channel mix

This is where the algorithm pool problem becomes visible — low-budget campaigns in platform-driven channels like Meta and Google don't reach your actual market. They reach the cheapest available audience, which is heavily weighted toward people who already know you.

Read your effectiveness verdict

You'll see your estimated effective reach, your frequency per person, which channels are operating within algorithm constraints, and a plain-language verdict on whether the campaign is likely to produce a real effect or just generate impressions. This is not a percise prediction!
