If you run e-commerce and BFCM is a make-or-break moment for your year, you're probably already thinking about offers, emails, and landing pages. Good. But have you really looked at your ad account?
Not at active campaigns or this month's spend. At the structure that needs to perform flawlessly during the busiest week of the year. A recent piece on Search Engine Journal makes the point clearly: BFCM ad prep isn't something you do a week before. It's something you do now.
At difrnt., the biggest BFCM losses we see aren't about weak offers. They're about unprepared accounts: campaigns stuck in learning phase, budgets too small for peak days, and retargeting that starts too late. If that sounds familiar, keep reading.
The account that sells on Friday trains on Monday
On Meta, each ad set needs roughly 50 results after its last significant edit to exit the learning phase. If you change your budget or audience three days before Black Friday, you're essentially resetting everything.
What does this mean in practice? If you're planning new prospecting campaigns for BFCM, they need to be live now. Not later in November, not "next week." Scale budgets in small steps: a 20% increase every few days is far safer than doubling your spend a week out.
We've seen this pattern across our e-commerce clients: the accounts that perform best during BFCM are the ones that entered November with stable campaigns. Not the ones that "turned on the engine" on November 20th. Preparing for the biggest sales weekend of the year looks a lot like a regular ad account health check. You clean up before the party, not during it.
A simple exercise we run with all our clients: three weeks before BFCM, we list every active campaign and check how many results each ad set has accumulated since its last major edit. Those that haven't reached 50 conversions are candidates for trouble. We either optimize them now or leave them untouched until after BFCM.
Google Ads can spend double in a single day
A detail many advertisers forget: Google can spend up to twice your set daily budget on any given day. The monthly cap stays at 30.4 times your average daily budget, but on peak days the platform allocates aggressively.
If your daily budget is sized for a normal day, on Black Friday you risk running out of budget by 2 PM. The fix isn't raising your budget on the day itself (that disrupts bidding); it's preparing higher budgets well in advance.
Another critical point: new Google Ads assets (images, copy, promotion extensions) need to be uploaded at least two weeks before the sale. Google needs review time, and during BFCM the approval queue grows significantly. We've had clients whose new assets sat in "pending review" through the entire BFCM week. You don't want that.
If you haven't recently reviewed how budget control works across Google Ads channels, now is the time. Performance Max and cross-channel campaigns have their own allocation rules that can catch you off guard.
Here's a quick calculation: if your normal daily budget is $500, Google could spend $1,000 on Black Friday alone. But if the monthly total exceeds $15,200 (30.4 x $500), campaigns stop serving entirely. Plan your budgets for the full month of November, not individual days.
Seasonality adjustments aren't a magic button
Google Ads offers a feature called seasonality adjustments that seems purpose-built for BFCM. But it works differently than most people expect.
Seasonality adjustments are useful only for short windows (seven days max) where conversion rates jump by more than 30%. And only on campaigns with enough conversion history. For longer promotions or smaller shifts, manually adjusting your ROAS target is more effective.
Why does this distinction matter? Because we've seen accounts where someone enabled a seasonality adjustment for all of November, estimating a +50% conversion rate lift. The result: Smart Bidding bid aggressively from day one, burned through budget on expensive traffic, and ran dry exactly during BFCM weekend, when it was supposed to perform. The difference between a well-tuned account and one with generic settings is the same as in any other period: it comes from preparation, not improvisation.
What you do in December matters just as much
Most BFCM campaigns go dark on December 1st. That's a mistake.
People who visited your site during BFCM week but didn't buy are the most valuable retargeting audience of the year. They already know what you sell, they've seen your prices, and many are in the decision phase. Target them in December with shipping deadline messages, not bigger discounts. "Order by December 15 for delivery before Christmas" works better than "another 10% off."
And when your promotion ends, don't reset budgets and targets overnight. Transition in steps: reduce budgets gradually over 3-5 days, adjust your ROAS target incrementally. A sudden change sends campaigns back into the learning phase, right when you need stability.
BFCM is not a one-day event. It's a three-phase sequence: preparation (now), execution (BFCM week), and capitalization (December). The accounts that treat all three phases seriously win the quarter. The rest just win Friday.
One more thing: document what worked. Not just sales numbers, but which ad types performed, which audiences converted, and which messages resonated. Next year, you'll have an advantage that no amount of preparation can replace: your own BFCM performance data, specific to your business and your customers.
