Black Friday 2026: how to prepare your e-commerce?

It's almost time: Black Friday 2026 falls on Friday 27 November, followed by Cyber Monday on 30 November.

For an ecommerce business, however, Peak Season starts much earlier.

Shopify’s BFCM 2026 strategies emphasise the importance of preparing in advance: in 2025, Shopify merchants generated $14.6 billion during the Black Friday-Cyber Monday weekend, up 27% year on year.

Competition grows alongside demand. Audiences, offers, creative and infrastructure should therefore be tested throughout October and the first weeks of November.

A strong Black Friday marketing strategy starts with a simple question: what do we want to achieve beyond the revenue spike of those few days?

Acquiring new customers, increasing AOV, clearing stock, reactivating existing customers or generating a second purchase all require different offers and campaigns.

The offer comes before the discount

"20% off everything" is easy to communicate. It is equally easy to erode margin on products that may have sold anyway.

Before choosing the discount, it is worth looking at margin, stock, AOV and expected customer value.

Options can include bundles, tiered discounts, spending thresholds, gifts with purchase, early access or offers reserved for existing customers.

In its Black Friday 2026 checklist, Shopify recommends defining promotions, inventory, fulfilment and the customer journey in advance, reducing the need for rushed commercial decisions during the peak.

The aim is to know which products can sustain a strong discount, which should be protected and which can help increase basket value.

That also affects media planning: an offer with limited margin leaves far less room for rising CPA and CPC.

Feeds and Merchant Center should be ready before campaigns

For Black Friday ecommerce, the catalogue is part of the campaign.

Incorrect prices, outdated availability or disapproved products become especially costly when both traffic and budgets increase.

In Google Merchant Center, it is worth checking at least price, availability, GTIN, product titles, images and landing pages.

For discounted products, Google allows advertisers to use sale_price together with sale_price_effective_date, defining exactly when the promotional price should become active.

The Google Merchant Center documentation also recommends specifying dates, times and time zones correctly.

This reduces last-minute manual updates and the risk of the feed, website and campaigns showing different prices.

Merchant Center Promotions can also be prepared in advance with validity periods and promotional codes aligned with the offer.

Tracking: find problems before 27 November

Black Friday week is a particularly bad time to discover that purchase is being duplicated or Google Ads is optimising towards the wrong Conversion Action.

Before Peak Season, it is therefore worth validating GA4, Google Ads, Enhanced Conversions, Consent Mode and any server-side tracking setup.

For Shopify stores, it is also useful to check how events are being sent following recent changes to Google integrations. We covered this in more detail in our guide to Shopify and GA4.

The essential checks are fairly simple: transaction_id, revenue, currency, order count and deduplication.

You also need a pre-Black Friday baseline.

Conversion rate, CPA, ROAS, AOV and Revenue per Visitor from normal trading weeks help show how much the peak is genuinely improving performance and how much comes simply from higher market demand.

Google Ads: prepare budget and bidding before the peak

During Black Friday, search volume, conversion rates and competitive pressure can change quickly.

That requires flexible budgets and frequent campaign monitoring.

Google points out, however, that Smart Bidding is already designed to handle much of normal seasonality.

Seasonality Adjustments are intended mainly for situations where advertisers expect an exceptional change in conversion rate over a short period, typically one to seven days.

They can therefore make sense for a particularly strong, time-limited promotion. Applying them across the whole Peak Season can add complexity without much benefit.

Before the event, it is more useful to review budget caps, Target ROAS or Target CPA, product priorities and Conversion Actions.

The pace of changes matters too. Constantly adjusting targets, budgets and creative during the peak makes it much harder to understand what is actually driving performance.

CRM: Black Friday starts with customers you already know

A significant share of demand can be built before the promotion begins.

Email, SMS and CRM make it possible to work with early access, VIP customers, recent customers, high-value customers and inactive users.

This is also where automation becomes particularly important.

Welcome, cart abandonment, checkout abandonment and post-purchase flows should all be reviewed before traffic increases, avoiding unnecessary overlap with promotional campaigns.

In our quick guide to ecommerce email automation, we looked at how different flows can support different moments in the customer journey.

During Black Friday, segmentation also helps protect margin.

A loyal customer might receive early access. An undecided prospect may need a different message.

Someone who has just purchased should leave communications that continue promoting the same discount.

Checkout, mobile and fulfilment: what happens after the click?

An effective campaign achieves little if checkout becomes the bottleneck.

Before the peak, test mobile experience, speed, discount codes, payment methods, shipping costs and messaging around delivery and returns.

Shopify includes checkout, inventory and fulfilment among the core elements of its BFCM 2026 preparation checklist.

Stock levels should also inform media decisions.

Aggressively promoting a bestseller with limited availability can mean spending budget to drive users towards a product that disappears after a few hours.

Unclear delivery times can create the same problem by turning high-intent traffic into checkout abandonment.

The experience needs to withstand the peak from the first ad through to the order confirmation.

Which KPIs should you monitor during Black Friday?

Revenue and ROAS will inevitably receive most of the attention.

On their own, they can tell an incomplete story.

During Peak Season, I would also monitor conversion rate, AOV, CAC, new customer rate, cart abandonment, checkout completion and margin.

For ecommerce businesses with a large existing customer base, it is useful to separate revenue from new and returning customers.

After the weekend, another KPI becomes even more interesting: how many new customers purchase again?

Black Friday can attract customers who are highly sensitive to discounts and disappear as soon as full prices return.

The true result therefore becomes clearer in the following weeks through repeat purchase rate, retention and the value of the cohort acquired during the promotion.

Black Friday 2026: an essential checklist

By November, the following areas should already be clear:

• offer, margins and priority products;
• feeds, promotional prices and availability;
• tracking and Conversion Actions;
• campaign budgets and bidding;
• CRM segments and automations;
• checkout, payments, shipping and fulfilment;
• pre-event KPIs to use as a benchmark.

Black Friday 2026 concentrates an enormous amount of demand and competition into a very short period.

The strongest Black Friday ecommerce strategies therefore begin well before 27 November, while there is still time to fix feeds, measurement, creative and the customer journey.

For an ecommerce business, arriving at Peak Season with these elements already aligned means using the spike to scale what works.
