Left it until November? Your ads can still win you Black Friday.

Black Friday

Spooky season may be over, but don’t let Peak be your next jump scare. The best Black Friday plan isn’t a bigger discount or a louder ad. It’s knowing what your customers actually responded to last time, and the good news is, there’s still time to use that data.

Picture your ideal customer scrolling their feed. In the split second before they see an ad, advertisers are competing in an auction for that one view. Now picture it during Black Friday week, when far more brands are bidding for the same moment.

That’s the environment your ads will walk into in a few weeks. In our experience, the brands that do well aren’t the ones shouting loudest during the week. They’re the ones that use the weeks before it well.

A familiar autumn pattern

Our paid media team executes campaigns on Meta, Google and TikTok for some of the world’s biggest brands, and they see the same thing every year. The offer gets signed off early, but the ads get made late. And the decision about which ads to run often comes down to a gut feeling about what “did well last year”.

Black Friday lands on 27 November, with Cyber Monday on the 30th. That’s under four weeks away. If your creative isn’t briefed yet, the week isn’t lost, but the next few days will matter far more than any last-minute change to your discount.

Why the ads themselves decide the week

Put simply, attention gets more expensive, and the platforms reward the ads people actually stop for. Nielsen and NCSolutions’ analysis of nearly 500 campaigns found creative accounts for 47% of the sales lift from advertising, more than reach (22%), brand (15%) or targeting (9%). And platforms like Meta now use AI-driven delivery that rewards creative variety rather than creative perfection. The algorithm needs options.

Two things quietly drain the budget during peak week: 

The first is creative fatigue. Show the same ad to the same people too often and they stop noticing it. Results drop and each sale starts to cost more. It happens faster than most teams expect even in a normal month: TikTok’s own guidance is to update creative at least every seven days. In a week as intense as Black Friday, that clock runs faster still.

The cost adds up quickly. As an illustration, a campaign that launches at a £12 cost per acquisition can climb to £22 within a fortnight with nothing changed in targeting, bidding or budget. Worse, a tired ad sends weak signals back to the platform, which adjusts its predictions and raises the price of everything else you’re running.

The second is too little variety. Meta now uses the creative itself to decide who to show it to. It’s looking for a range of messages, visuals and formats so it can reach different kinds of buyers: the gift shopper, the bargain hunter, the person who’s been eyeing your product since September. One ad resized three times doesn’t give it much to work with. Meta’s large-scale ad tests found visually distinct creatives drove up to 32% higher performance than similar ones.

Think of it like a shop window on the busiest street of the year. A great window draws people in, but if it never changes, the same passers-by stop looking. The brands that do well refresh their window on purpose, based on what actually brought people through the door.

Three questions to answer this week

Before a single new ad is designed, we’d encourage every team to answer these with evidence rather than memory.

What worked last time, and why? Not just “the red video did well”, but what specifically about that video. Was it the message (a sharp price, a gifting angle, a deadline), the first three seconds, or the format? The opening hook of a video and the headline of a static ad carry most of the impact, so that’s often where the answer lies.

What didn’t work, and what will we stop doing? Dropping weak ideas frees up budget and design time for the strong ones. It’s the least glamorous decision you’ll make, and one of the most valuable. It’s also easy to hold onto a former winner for too long, particularly one that was flying just weeks earlier.

How many new ads do we actually need? Too few and your ads tire halfway through the week. Too many and you waste production time and spread the budget so thinly that nothing gets a fair chance. As a reference point, Meta has described at least 20 different versions of creative as an emerging best practice for Advantage+ shopping campaigns, and many teams hold back around a fifth of budget for testing new assets, which is also the ceiling Meta suggests for its own creative testing tool.

Most teams end up answering these the week before, from a spreadsheet pulled together in a hurry. If you can answer them in the next few days, you’re still ahead of most of the market.

Know the warning signs before peak week

Fatigue tends to show up in a predictable order, and knowing it means you can act before it costs you.

Frequency rises first. A widely used rule of thumb is that once average frequency passes 2.5 to 3.0 in prospecting audiences, you’re cycling through the same people rather than reaching new ones. Click-through rate drops next, and a 20% fall over a rolling seven days is the audience telling you they’ve seen enough. Cost per acquisition climbs last, by which point money has already been lost.

During Black Friday there’s very little time to react, so it pays to have replacements ready. Refreshing the hook while keeping the core message, or shifting format (turning a static into a motion graphic, or cutting a 30-second video to six seconds), can reset attention without a full rebuild. We’ve written about this in more depth in When Good Ads Go Bad: The Hidden Cost of Creative Fatigue.

A few principles that help

Keep your learnings separate by platform. What makes a TikTok video work is different from what makes a Google banner work, and blending them together hides the real lessons.

Ground the plan in your own results. Industry benchmarks are useful context, but your account history tells you what your customers responded to. That evidence is worth building on, and it should support your team’s judgement rather than replace it. 

Track how long your ads typically last. If your history shows creatives burning out after around 14 days, plan to bring new ones in around day 12. Getting ahead of the decline is always cheaper than reacting to it.

Be realistic about volume. With weeks rather than months to go, a recommended number of new ads is only useful if your team can produce and approve them in time. A brilliant ad stuck in a three-week sign-off loop won’t make it to peak week. A plan you can’t deliver isn’t really a plan.

Working backwards from 27 November

If your brief is signed off this week, new ads can realistically go live by the middle of the month. That still gives the platforms around ten days to learn what works before costs peak, and gives you time to back the winners and swap out tired ads before the big day. Have a reserve of approved creative ready to go, so you’re never caught without options mid-week.

The same approach works beyond Black Friday too. Once Cyber Monday is done, look back at last year’s festive period to plan your Christmas gifting campaign, then do the same for Boxing Day and the January sales. Each period gets its own evidence-based plan, and this year’s Black Friday learnings become the starting point for next year’s.

Start with what you already know

The best Black Friday plan isn’t a bigger discount or a louder ad. It’s knowing what your customers responded to last time, letting go of what they ignored, and making enough fresh creative to stay interesting all week.

The good news is you already have that evidence. It’s sitting in last year’s ad accounts. It just needs pulling out this week rather than the week before.
