Paid media seasonality: plan the year, not the month
CPMs, demand, and competition move in annual rhythms. Map the calendar, pre-position before peaks, use quiet seasons to build.
Auction prices breathe with the calendar: retail quarters inflate CPMs for everyone, B2B demand dips in holiday stretches, and every vertical has its own peaks — travel booked in January, budgets spent in Q4. Accounts managed month-to-month keep re-discovering these rhythms as surprises. The fix is boring and powerful: plan against the year.
Map your seasonality from your own data
Pull two or three years of monthly performance — cost, volume, conversion rate — and chart the rhythm. Layer the external calendar on top: industry events, procurement cycles, holidays across your markets. Most accounts show patterns nobody had made explicit; write them down and the whole year becomes navigable.
Pre-position before peaks, don't react during them
Peak season is the worst time to launch: costs are up, and new campaigns burn their learning phase at the year's most expensive prices. Enter peaks with proven creative, warmed audiences, and retargeting pools filled during the cheaper weeks before. The winners in December did their testing in October.
Use the quiet seasons deliberately
Low-demand stretches are cheap-attention laboratories: run the creative tests, try the new channel at low stakes, build audiences and content assets. Cutting spend to zero in quiet months saves pennies and costs the platform history that makes the next peak efficient.
Budget annually, adjust monthly
A yearly envelope shaped to the seasonal map — heavier where returns are proven, lighter but never dark in troughs — beats twelve identical monthly budgets. Review monthly against the efficiency signals, and shift within the year rather than renegotiating from zero each quarter.
Write next year's notes this year
After each peak, hold a short retro while it's fresh: what sold, what broke, what you'd pre-position earlier. Seasonal knowledge is the most perishable institutional memory in marketing — the calendar makes it compound instead.
