Preparing your online store for Black Friday and the holidays: the peak-season playbook

The same film plays out every year. Around the middle of November, an online store owner suddenly realises Black Friday is a few days away, and the scramble begins: banners made the night before, discounts picked at random, stock that runs out, a site that loads slowly under the traffic, and a team taking orders late into the night. The result is predictable — fewer sales than there could have been, angry customers, and a week of chaos no one learns anything from for the following year.

The uncomfortable truth is that the peak season isn't won in November. It's won in October. Black Friday 2026 falls on Friday, 27 November, Cyber Monday on 30 November, and "Black Week" runs from 23 to 29 November — most stores launch their promotions from the start of the week, not only on the Friday. And the winter holidays stretch the peak all the way to Christmas. That means nearly a month into which, for many stores, a significant share of the whole year's sales arrives. And preparing for that month has to happen now. In this article I'll give you the complete plan — site, stock, delivery, offers and campaigns — in the order worth tackling them.

Why the peak season is decided in October

Shopper behaviour has changed radically in recent years. International e-commerce research published by Think with Google shows that holiday shopping now starts earlier and spreads across several months: a large share of shoppers begin their search before Black Friday, and the great majority before December 1. In October and November a "deal-seeking" mindset dominates — people ready to buy, but carefully comparing price, quality and terms before they decide.

The practical takeaway for you is simple: if you wait until 25 November to prepare your store, you've already missed the weeks in which the customer does their research and builds their list. Your presence — in search, in the feed, in the inbox — has to start in October, so that when the moment of decision arrives, your store is already on the list. Early preparation isn't a nice-to-have; it's the difference between catching the wave and chasing it.

Step 1: the site has to survive the peak

None of the rest of the plan matters if the site goes down on the very day you have the most traffic. The first thing to check is loading speed. On peak days, traffic can be several times higher than usual, and a site that performs acceptably on normal days can become slow or unreachable under pressure. Every second of delay cuts your conversions — and on a day like Black Friday, those seconds translate directly into lost sales. If you haven't checked performance recently, start with the guide on website speed and Core Web Vitals and run a load test before November, not during it.

The second critical point is the mobile and checkout experience. Most shoppers will reach you from a phone, and a long or confusing checkout process is where you lose the most sales exactly when you have the most traffic. Walk the entire path yourself, from a phone — from the product page to a confirmed payment. Every extra step, every unnecessary field, every display glitch costs orders. The causes of abandonment and the fixes I covered in the article on cart abandonment and checkout optimisation; it's worth re-reading now, not in December.

Step 2: stock and delivery — promises you can keep

A great offer on a product that's out of stock is the fastest way to turn an excited customer into a furious one. Before the season, look at your sales history and identify the star products — the ones you'll promote — and secure stock for them with a comfortable margin. Talk to suppliers early, because they're overloaded in this period too. If you don't have a clear stock-tracking system, now is exactly the time to set one up: you'll find a practical guide in the article on inventory management for the online store.

Equally important is not promising what you can't deliver. At the peak of the season, couriers are overloaded and lead times stretch. Be realistic and transparent about delivery times — a customer who receives their parcel when you said will be happier than one you promised "tomorrow" and who got it a week later. Set up your logistics early, discuss capacity with your courier partners, and display the real timeframes clearly on the site. Everything about how to organise delivery I wrote in the guide on delivery for the online store in Moldova.

Step 3: the offers and the pricing strategy

The biggest mistake with offers is throwing discounts around at random, "like everyone else." A well-thought-out peak campaign has a structure. Pick a few hook products with aggressive discounts that pull people onto the site, and build offers with a better margin around them — bundles, "buy two, get the third free," free-shipping thresholds. The goal isn't just to sell a lot, but to sell profitably and raise the average order value, not only the number of orders.

A credibility detail that matters enormously: don't inflate prices before the discount. Customers in 2026 check price history and instantly spot a fake "discount" — and once caught, a store loses hard-won trust. A real discount, communicated honestly, sells more in the long run than an impressive but fake percentage. Prepare your copy, banners and campaign pages in advance, so that on the day itself you improvise nothing.

Step 4: the marketing campaigns — where and when

This is where October's preparation turns into November's sales. The winning strategy works across several channels, in waves. Before the season (October to mid-November) you build the audience and the anticipation: organic posts, collecting e-mail addresses with a "be the first to hear about the deals" offer, awareness campaigns. During the peak, you switch paid advertising to maximum and send the decisive messages.

On paid, the two main engines remain Meta ads (Facebook and Instagram), for discovery and generated demand, and Google Ads, for shoppers already actively searching. But the best return in this period usually comes from the people who already know you: those who visited your site without buying, and your subscribers. Prepare in advance your remarketing campaigns to site visitors and a sequence of e-mails to your customer list — a pre-launch announcement, the message on the offer day, a "final hours" reminder. The audience you own costs no ad money and converts best.

Step 5: after the holidays — the second sale

The final mistake is treating 30 November as the finish line. In reality, the wave of new customers you brought in during the season is the most valuable asset you have for the following year — if you don't let it evaporate. A Black Friday buyer who doesn't hear from you until next year is a one-off sale; the same buyer brought back with a good message in December or January becomes a loyal customer.

Plan ahead for what you do after the peak: a thank-you e-mail, a holiday offer for new customers, enrolling them in a loyalty program. The peak season isn't only about how much you sell that month, but about how many long-term customers you keep after it. The stores that truly win aren't the ones with the biggest discount, but the ones that prepare from October and treat November as the start of a relationship, not a one-day race.

For further data on shopper behaviour in the holiday season, you can consult the research published by Think with Google. Keep the main idea in mind: the peak season isn't a one-day race, it's a month prepared from October. The stores that win have a site ready to hold up, secured stock, organised delivery, well-planned offers and campaigns launched early.
