Black Friday and Cyber Monday are won in the months before they happen, not in the week they arrive. By the time late November comes around, the accounts that perform are the ones that did the quiet work early. The ones that struggle are usually trying to make big changes at the exact moment they can least afford the risk.
So this is the case for starting now. Not because the calendar says panic, but because the few things that actually move BFCM results all need lead time. Leave them late and you are paying more for less, right when volume and competition are at their peak.
Here is what we work through with clients in the run-up, roughly in the order it matters.
Why the timing actually matters
There are two reasons, and the first is the one people think of. Google's bidding does not respond instantly. When you change a bid strategy, a budget, or a conversion setup, the system goes through a learning period before it settles. That learning is noisy and often expensive. You do not want it happening during your highest-traffic, highest-cost week of the year.
The second reason is easy to underestimate, and it is just as important. There is a real pile of preparation work, and almost all of it can be done ahead of time. Ad copy needs writing and testing. Images and seasonal creative need producing. The Shopping feed needs cleaning, updating and checking. Campaign structure, budgets and offers need reviewing. None of that goes well in a rush, and the teams that struggle are usually the ones who leave the whole lot until November and try to do it at once.
The goal is simple. Walk into BFCM with the groundwork already done and proven, so peak week is about managing and fine-tuning, not building. Get the structural decisions made and bedded in well before the rush, and use the weeks before to prepare and test the creative and feed properly.
That is why a piece written in late July is not early. It is about right.
Settle your bid strategy early
The single most common BFCM mistake we see is switching bid strategy too close to the event. Someone moves from Maximise Conversions to a Target CPA, or flips to Target ROAS, in early November because they read it was better. Then they spend the most important fortnight of the year inside a learning period.
If you are planning a strategy change, make it now. Give it weeks of stable data so it is fully out of learning before peak. If your account is not ready for an automated strategy yet, that is fine. It is better to run a proven manual or Maximise Conversions setup through BFCM than to gamble on a smarter strategy that has not had time to learn.
This does not mean setting it and never touching it again. You will still want to watch performance and optimise as you go, and most accounts will need some tuning along the way. The point is that the big structural moves happen early, so any changes during peak are small and considered rather than a scramble to rebuild. The closer you get to BFCM, the smaller the changes should be. By November you want to be fine-tuning, not rebuilding the machine.
Get your conversion tracking right before it counts
Smart bidding is only as good as the signal you feed it. If your conversion tracking is double-counting, missing values, or firing on the wrong action, the system optimises toward the wrong thing, and BFCM is when that mistake gets expensive at scale.
Now is the time to check the boring but crucial stuff. That each conversion fires once per action and is not double-firing from a duplicate tag. That conversion values are passing through correctly, not flat or zero. That you are not accidentally counting micro-conversions as sales in the same bidding pool.
One setting worth checking on purpose is the conversion count, whether each action is set to count every conversion or just one per click. It is easy to overlook and it changes what the system optimises toward. Ecommerce sales usually want every purchase counted, since one customer can buy more than once. Lead gen usually wants one per click, so repeat form fills do not inflate the numbers. Review it per action and make sure each one matches what you actually want to measure.
For ecommerce especially, clean revenue data is what lets the machine bid toward profit instead of just clicks.
If you are running lead gen alongside, the same applies to your forms and your offline conversions. The cleaner the signal now, the better the system performs when it counts.
Decide your budget and pacing plan
BFCM is not the time to discover your daily budget is capping you. Work out now what you are willing to spend across the peak window, and how you want it shaped. Some businesses go hard on the Friday and Monday. Others run a longer promotional window that starts mid-November and tails into December.
Whatever the shape, set the plan early and make sure the account can actually spend it without throttling. A budget that doubles overnight can itself nudge the system back into learning, so a gradual ramp in the weeks before tends to behave better than a hard switch on the day.
Feed, structure and creative: ready, not rushed
For ecommerce, your product feed is the engine of Shopping and Performance Max, and it deserves its own attention. We have written separately about preparing your Google Shopping feed for BFCM and why the work starts months out, so we will not repeat all of it here. The short version: titles, images, pricing, availability and identifiers all need to be clean and current before peak, because the feed quietly decides where and whether your products show.
Beyond the feed, get your promotional assets in early. Sale copy, updated images, any seasonal creative, promotion extensions and sitelinks reflecting the actual offer. Build and load them ahead of time so that going live on BFCM is a scheduled switch, not a scramble. If you are testing new creative, test it now while clicks are cheaper, so you go into peak with proven assets rather than guesses.
Don't forget the CRM side
The ad click is the start, not the finish. A lot of BFCM spend leaks after the click because the journey behind it was not ready. Wherever your customer data lives, whether that is HubSpot, Klaviyo or another CRM, the after-click side needs to be ready too.
If you capture leads, make sure the forms, follow-up and routing can handle the volume, and that nothing important depends on a person manually picking things up over a holiday weekend. If you sell direct, this is the moment to set up the post-purchase side properly, because the real value of BFCM is not the first order, it is what those customers are worth afterwards. Abandoned-cart flows, post-purchase nurture, and a clean record of who bought what all turn a one-off discount hunter into a repeat customer.
When your CRM and your ads talk to each other, you can also see which campaigns brought buyers who actually stuck around, not just who converted once on a deal. That is the difference between spending on BFCM and investing in it.
The week itself: small moves, not big rebuilds
When BFCM finally lands, the best operators do surprisingly little. They watch pacing, they make sure nothing has broken, and they resist the urge to overhaul anything mid-event. The work was done in the months before. Peak week is for monitoring and small, considered adjustments, not bold structural moves.
That calm is only possible if the groundwork is in place. Which brings it back to the one idea worth holding onto: the accounts that win BFCM are the ones that got quiet and methodical early.
If you want a second look at whether your account is set up to handle peak, that is a conversation worth having now while there is still time to act on it. By November the options narrow. Right now, they are wide open.
