Seasonal Paid Media Planning: How to Not Get Caught Out

Every year, around the second week of November, I get a flurry of messages that all say roughly the same thing: "We want to do something for Black Friday - can we get it live by Friday?" And every year the honest answer is yes, something can go live - but the brands that actually win peak season decided what they were doing in September.

Seasonality isn't just Black Friday. Depending on the business it's Christmas, January sales, Valentine's, Mother's Day, Easter, back to school, the end of the tax year, wedding season, the Fringe, or simply "the quarter when everyone renews". The pattern of mistakes is the same regardless of the date on the calendar: too little preparation, too much reactivity, and no plan for what happens afterwards.

Here's the framework I use to plan seasonal paid media so that peak is a controlled push rather than a panic.

Start with last year's data, honestly

Before deciding anything, look at what actually happened last time. Not the anecdotes - the numbers. Week by week, in the ad platforms and in GA4:

• When did search demand start rising, and when did it peak? Google Trends is useful here if your own data is thin.
• How did CPCs move? In most retail categories they climb sharply from early November and don't come back down until January.
• When did conversion rate peak? It's often not the same week as traffic.
• Where did you run out of budget, and what did that cost you in lost impression share?
• What happened in the weeks after - the post-peak slump and the January rebound?

If you don't have last year's data because the account is new, use category benchmarks and plan conservatively. But if you do have it, it's the single most valuable input you'll get.

Build the calendar backwards from the peak

Work out the date that matters most - the day you expect the most revenue - and plan backwards from it in phases:

Eight to ten weeks out: foundations

This is when tracking gets checked, feeds get cleaned, landing pages get built and creative gets briefed. It's also when you should be building audiences - site visitors, engaged social audiences, email lists - because those are the people who'll convert cheaply when the pressure's on. Remarketing lists built in October are worth far more than cold traffic bought in late November.

Four to six weeks out: warm-up

Increase spend gradually on prospecting so that bid strategies have stable data going into peak, rather than being shocked with a 300% budget increase on the day. Launch any "coming soon" or early-access messaging. Test creative now, while clicks are cheaper, so you know what works before it matters.

One to two weeks out: positioning

Final checks on promotions, pricing and feed accuracy. Load scheduled campaigns and ad variations ready to switch on. Confirm budgets with whoever signs them off. Agree what "we're pulling back" looks like if something goes wrong.

Peak

Monitor daily, change little. The worst thing you can do during peak is make large structural changes that reset learning. Adjust budgets, swap creative, fix anything broken - but resist the urge to rebuild.

Post-peak

Plan this phase before peak starts, because nobody has the energy to plan it afterwards. Remarket to everyone who visited and didn't buy. Shift messaging from offers to gifting deadlines, then to January. Pull spend back before the slump, not during it.

Budget: decide the rules before you need them

Seasonal budget conversations go wrong because they happen in the moment. Agree in advance:

• The total seasonal budget and how it's phased week by week
• What performance threshold unlocks more spend - "if ROAS stays above X for three days, we can add Y"
• What threshold triggers a pull-back
• Who can approve a change, and how quickly

Set daily budgets with the understanding that Google can spend up to twice the daily figure on any given day. Use shared budgets or portfolio strategies where it makes sense, and keep a reserve. Running out of money on the busiest afternoon of the year is painfully common and entirely avoidable.

Bidding: give the algorithm a heads-up

Smart Bidding reacts to changes in conversion rate, but it reacts with a lag. If you know a promotion will lift conversion rate for a defined period, Google Ads' seasonality adjustments let you tell the system in advance, so it bids up appropriately from the start rather than catching up on day three. Use them for short, sharp events - a weekend sale - not for a six-week season. For longer periods, gradually adjusting targets is safer.

And be realistic about targets. Insisting on your normal ROAS target during Black Friday, when CPCs have doubled and every competitor is discounting, usually just means the system refuses to compete and you watch impression share evaporate. Decide what an acceptable peak-season target is, and accept that it may be different from March.

Creative and messaging: have the sequence ready

You'll need more creative variations during peak than at any other time, and you won't have time to make them once it starts. Prepare the sequence in advance: teaser, launch, mid-event reminder, last chance, delivery cut-off, post-event. Make sure the ad, the landing page and the site banner all say the same thing on the same day - mismatches between a "40% off" ad and a site showing full price are the fastest way to waste a peak-season click.

Operational things people forget

• Stock. There is nothing more frustrating than a campaign working perfectly for a product that sold out on day one. Use custom labels or inventory rules to pull products automatically.
• Delivery cut-offs. Update ad copy and extensions as the last order dates approach - and then switch to gift cards or January messaging.
• Customer service capacity. More leads and orders means more questions. If response times collapse, conversion rate follows.
• Site speed. Peak traffic on a slow site is money straight down the drain. Test it under load before November.
• Tracking. Verify it works after every site change. A broken purchase event during peak means the bid strategy is flying blind at the worst possible time.

The quiet season matters too

Seasonal planning isn't only about ramping up. Knowing when demand drops is just as valuable - it's when you pull spend back, test new things cheaply, build audiences and fix the structural problems you didn't have time for in November. Brands that treat January as a planning month rather than a disappointing one go into the next peak in a much stronger position.

If your peak season is approaching and you're not sure the account is ready for it, a quick review now is a lot cheaper than finding out in the middle of it. That's exactly what a free PPC audit is for.
