Media planning: media mix, seasonality and category benchmarks

How to spread an advertising budget across media and months, starting from what your category does: competitor spend, open windows, objectives and scenarios.

Updated October 6, 2026 · MAPS editorial team

In brief

Media planning decides how to spread an advertising budget across media — TV, online, radio, out-of-home, print, cinema — and over time, to reach an objective: awareness, consideration or conversion. A good plan starts from what your own category does: how much it spends, on which media, in which months, and where it leaves open space.

The questions of media planning

How much — the total budget, and how it compares with what the category spends.
Where — the media mix: how much on each, and why.
When — the spread across months: continuity, concentration, peaks.
What for — the objective, which changes the right media. Broad-reach media build awareness; more targeted ones drive action.

Two concepts keep coming up. Reach: how many people in the audience see the message at least once. Frequency: how many times, on average, they see it. GRPs (gross rating points) combine them: reach percentage × average frequency.

How to do it

1. Look at the category

How much it spends in total, how many advertisers, how concentrated the spend is, the weight of each medium. Comparing your share of spend (share of voice) with your market share tells you whether you’re investing more or less than your weight.

2. Look at competitors, one by one

Who puts everything on one medium, who has diversified, which media nobody holds. A medium left open can be an opportunity, or a medium that doesn’t work in the category: you need to figure out which.

3. Read the seasonality

Month by month, the category’s peaks and quiet periods. Investing in the peak means competing with everyone; investing in the quiet months can deliver more visibility for the same budget, if the demand is there.

4. Allocate the budget

By objective, medium by medium, with the category benchmark alongside. Then across the months: the calendar.

5. Simulate before deciding

What happens with a different budget, or by shifting share between media. Compare several scenarios before choosing.

An example. “Zampa Felice,” a fictional cat food brand, finds that the category concentrates almost all its spend on TV and in the fall months, and that digital is barely held by the top five advertisers. With a small budget, it chooses not to compete on TV in the fall: it concentrates spend on digital between spring and summer, when the category goes quiet.

The most common mistakes

Copying the leader. Its mix makes sense for its budget, not yours.
Ignoring seasonality. The same budget is worth much less in the months of peak pressure.
Media chosen out of habit. Each medium should be chosen for the objective.
Estimates presented as real data. If an estimate stands in for a missing figure, it has to be declared.
No alternative scenario. A single plan doesn’t let you see how robust it is.

How MAPS does it

In MAPS, the Media Planner reads Nielsen AdQuest exports — annual and, if you like, monthly, for the current and previous year; it recognizes the format on its own, and there’s an export guide. From them it derives the market (total spend, advertisers, media, concentration, media mix across TV, online, radio, out-of-home, print, cinema, rankings), the competitors (ranking, shares, head-to-head comparison, each one’s mix) and seasonality month by month: with the monthly files it’s the real data; without them MAPS estimates it from industry benchmarks and says so. In the Planning Studio you set budget and objective — awareness, consideration, conversion — and MAPS proposes how to allocate it across media next to the category benchmark; start from scratch or optimize a brand’s plan; then calendar, projections, “what if…?” and saved scenarios. A chat answers by running the numbers on the AdQuest data.

Frequently asked questions

What is media planning?

Planning how to spread an advertising budget across media and over time, to reach a communication objective.

What’s the difference between reach and frequency?

Reach is how many people in the audience see the message at least once; frequency is how many times, on average, they see it.

What is share of voice?

Your advertising spend as a share of the category total. Compared with market share, it tells you whether you’re investing more or less than your weight.

How do you choose the media mix?

From the objective, the audience and the budget, looking at what the category does: where competitors invest, which media are open, in which months there’s less pressure.
