Black Friday 2026 is on November 27. But for an online retailer, the campaign does not start then.

If the first serious Black Friday discussion happens in November, you are probably already late.

Stock must be secured. The site must handle the traffic. The ad budget must be planned. The courier must be able to handle the increased volume. Prices must comply with legal requirements. The email system and ad tracking must work.

And all of this must be checked before you send the first visitor to the promotion.

In our experience, one of the most common mistakes is starting the campaign itself too early, but preparing for it too late.

Those are two different things.

Preparation should start as early as possible. Advertising communication - when it makes strategic sense.

For products that are not highly seasonal and where we do not expect a new model shortly before November, there is no reason to wait until the last minute to plan.

What should the goal of Black Friday be?

For us, Black Friday is not necessarily the campaign from which the store should make the maximum profit on every single order.

Three other goals can be much more interesting:

attracting new customers, clearing inventory and increasing the future value of the acquired customer.

The latter is usually referred to as LTV - Lifetime Value.

If a customer makes their first order with a very strong Black Friday offer, but then comes back several more times over the following months, the economics of that first sale look completely different.

But that only works if you know what you are doing.

You can't reduce a product almost to its cost price, spend aggressively on advertising, and just assume that people will come back someday.

You need to be able to measure that.

10-15% off is not necessarily a Black Friday deal

If the store runs 10-15% discount campaigns all year long, the same offer at the end of November hardly creates the feeling of a special event.

Our approach is more direct:

either we can offer a truly strong price, in some cases as close as possible to cost, or we should ask whether it makes sense to participate in Black Friday at all.

This is not a universal rule for every store.

For some products, such a price may be financially impossible. For others, repeat purchases practically do not exist, and relying on future LTV would be a mistake.

But the idea is simple:

Black Friday should give people a reason to buy now, not just put a black banner over your regular monthly promotion.

Before setting the discount, calculate:

  • cost price;
  • shipping costs to you;
  • packaging;
  • payment fees;
  • ad spend;
  • shipping covered by you, if any;
  • expected returns;
  • service costs;
  • the actual value of repeat purchases.

Only then decide how aggressive the offer can be.

The most important pricing rule for Black Friday 2026

Here, preparation months in advance also has legal significance.

According to the latest information from the Consumer Protection Commission the “previous price” in a stated discount must be the lowest price applied during a period of no less than 30 days before the discount.

The CPC also states that the products, terms, and duration of the promotion must be clearly defined. According to the published guidelines, the discount period cannot be shorter than one day or longer than one month, with exceptions specified in the rules.

For Black Friday on 27 November 2026, this means that pricing history from the end of October onward already matters for how you present the discount.

Artificially increasing the price before the campaign just to slash it afterward is not a strategy.

The CPC continues to monitor exactly these practices, and in 2026 it published a case in which the promotional message “up to -70%” was deemed misleading because some of the displayed devices were not discounted.

Inventory can ruin perfect advertising

There is little point in achieving the best ad performance of the year if the product everyone wants sells out in the first few hours.

This is a problem we have seen many times: the store has enough stock overall, but not enough of the exact products that become the stars of the campaign.

That is why Black Friday planning should not be:

“We have 20,000 products in stock.”

The more important question is:

“Which 20 products do we expect to drive the main volume?”

If you have history from previous campaigns, use it.

Check:

  • which products generate the most orders on discount;
  • which have the highest conversion rate;
  • which products attract new customers;
  • which have enough margin for aggressive promotion;
  • which you can restock quickly;
  • which have variants - sizes, colors, or models - that may sell out unevenly.

WooCommerce places inventory among the key areas to prepare for the peak season and in 2026 pays special attention to the issue of different systems showing different stock levels. When selling through more than one channel, you need a reliable source of stock information.

The best campaign is useless if the site goes down

This is one of the things merchants often underestimate.

You pay more for ads.

You send an email to the entire database.

You launch Meta, Google, remarketing, and social campaigns at the same time.

People come.

And that’s exactly when the hosting decides it can’t take any more.

The problem is not theoretical. In WooCommerce’s Black Friday 2025 preparation study, 33.4% of surveyed merchants cited site performance optimization as a top priorityand another 7.5% planned hosting improvements. The survey covered 249 merchants and does not represent the entire market, but it is indicative of how active stores approach peak traffic.

What should be checked technically?

Not just the homepage.

Test the real customer journey:

category → filters → product → variant → cart → checkout → payment → order confirmation.

Also check:

  • on-site search;
  • AJAX requests;
  • cart behavior under caching;
  • the database;
  • external payment services;
  • courier integrations;
  • stock synchronization;
  • email sending;
  • tracking for Google Ads, Meta, and Analytics;
  • behavior with concurrent active users.

WooCommerce recommends load testing before peak periods and checking the full customer journey, including search, checkout, payments, and out-of-stock situations.

Black Friday is not the right time to find out how many users your server can handle.

You need to know that in advance.

One email can turn into a load test

This is especially important if you use a large in-house database.

In July 2026, the WooCommerce engineering team published an interesting internal case study: their newsletter campaign caused significant traffic to the site almost immediately after it was sent.

The reason is not only the people who open the email. Corporate email security systems can automatically open the links in the message to check them.

In its next major campaign, Woo spread sending across several hours and avoided the same sudden spike.

The takeaway is not to send fewer emails.

The takeaway is:

your marketing calendar and your infrastructure need to talk to each other.

Logistics are part of the marketing campaign

The store can handle 3,000 orders.

The question is whether you can fulfill them.

And whether the courier can deliver them.

During Black Friday, the load does not increase only on your side. The CPC explicitly warns consumers that during such campaigns courier companies can also be heavily loaded and deliveries may be delayed.

That is why, before the campaign, clarify:

  • the maximum daily processing capacity;
  • pickup times for shipments;
  • what happens when the usual volume is exceeded;
  • whether you have a backup delivery option;
  • how many orders the team can pack;
  • how the customer will be informed in case of delay.

Do not promise standard 24-hour delivery just because you can meet it in September without problems.

A realistic deadline you can meet is better than a promise that Black Friday makes impossible.

Preparation starts early. Advertising does not have to start early.

That is a distinction we would make especially clear.

A common tip is to start massive “warm-up” weeks in advance:

“Black Friday is coming.”

“20 days left.”

“Expect something huge.”

“Don’t buy yet.”

The last one can happen even if you do not write it.

If an existing customer knows that everything will be significantly cheaper in two weeks, why buy today?

Excessive early warm-up can delay purchases and reduce current cash flow right before a period when you will need a large budget.

Our approach is different.

We prepare early:

  • the offer;
  • the audiences;
  • the ad creatives;
  • tracking;
  • the stock;
  • the hosting;
  • the email database;
  • the landing pages.

But the moment when we start aggressive communication is chosen according to the specific store.

Build an opt-in audience before the campaign

There is a difference between telling people for weeks “wait for Black Friday” and building your own channel to potential customers.

You can collect voluntary sign-ups in advance for:

  • early access;
  • launch notifications;
  • limited quantities;
  • a specific product category.

This gives you an audience you can communicate with directly when the offer is already live.

During the short promotion period itself, the frequency can be significantly higher if the audience has consented to this kind of communication and the messages actually provide different information.

For large databases, pay attention to technical deliverability as well.

Google requires senders that send around 5,000 or more messages per day to personal Gmail accounts to use SPF and DKIM, DMARC, one-click unsubscribe, and comply with the other requirements for bulk senders. From November 2025, Google is strengthening enforcement of these rules.

Having 50,000 addresses in a database is not enough.

The email actually has to reach them.

The ad budget must match the ambition

The second common mistake is an amazing offer with a budget that runs out before noon.

Black Friday is a period of increased ad activity. If you plan to use the day to aggressively acquire new customers, the budget must allow for that.

This does not mean simply multiplying your usual daily budget by five.

You need to know:

  • how much you can pay for a new customer;
  • what you lose on the first sale;
  • what percentage of customers buy again;
  • what their average revenue is over a reasonable period;
  • how much stock you can sell;
  • how many orders the team can handle.

Google also gives special recommendations for Shopping and Performance Max during Black Friday. These include checking early whether the budget will limit the campaigns and adjusting ROAS targets in advance if needed.

For short promotions, where a large temporary change in conversion rateis expected, Google also allows seasonality adjustments. The company recommends this tool mainly for short periods of 1-7 days and significant expected changes; Smart Bidding usually tries to handle normal seasonality on its own.

Do not change these settings automatically just because it’s Black Friday. Use them when you have historical data and a reason for the expected change.

Prepare Google Merchant Center before the campaign

The product price on the site, the product feed, and the ad should tell the same story.

For discounted products, Google Merchant Center supports a separate attribute sale_price, and via sale_price_effective_date you can set the exact period of the promotional price. Google recommends keeping the base price submitted in price, and the promotional price separately in sale_price.

Before launch, check:

  • price;
  • sale price;
  • currency;
  • availability;
  • product variants;
  • images;
  • GTINs/identifiers, where applicable;
  • landing URL;
  • whether the ad leads to a product with the same price.

Do not start this check at 11:45 p.m. on Thursday.

Our example: 50% off phone cases

In one of our successful Black Friday campaigns, we worked with an online sale of phone cases.

The offer was simple:

50% off.

We didn’t complicate it with five different tiers, hard-to-use promo codes, and conditions the customer had to decode.

When the campaign launched, we came in with a large ad budget and presence across all major channels, and we emailed our own audience daily during the active period.

The result was a huge volume of sales.

That doesn’t mean that “50% + lots of advertising” is a universal formula.

The more important lesson is this.

We had:

a strong, easy-to-understand offer + enough media weight + repeated reach to the audience in a short period.

If we had given 12% off and limited advertising to the normal daily budget, it would have been a completely different campaign.

Track new customers separately

If you treat Black Friday as a customer acquisition tool, then turnover on November 27 alone is not a sufficient metric.

Split at least:

  • new and existing customers;
  • cost per new customer;
  • average first-order value;
  • gross profit after variable costs;
  • percentage of returned or undelivered orders;
  • repeat purchase;
  • customer value after the campaign.

If you sold €100,000 but acquired customers who never come back, the result is one thing.

If the same campaign created a base of customers who keep buying in December, January, and the months after, the result is another.

That is why LTV should be part of Black Friday analysis, not just ROAS on the last Friday in November.

How should we organize Black Friday 2026 prep?

8-12 weeks in advance

Define the campaign goal.

Choose the products.

Calculate the real allowable price.

Negotiate with suppliers.

Plan the quantities.

Set the ad budget.

Check whether the hosting and store can handle the expected traffic.

For products where you are waiting for a new model or seasonal change, leave the product selection itself closer to the campaign, but prepare the infrastructure in advance.

30+ days in advance

From this point on, the price history is especially important for how the future discount will be announced.

Finalize the core products.

Check stock levels.

Prepare the Black Friday pages.

Check Merchant Center.

Prepare the ad audiences.

Set up tracking for purchases and revenue.

Collect opt-in sign-ups if that is part of the strategy.

2-3 weeks in advance

Run a load test.

Check the checkout on different devices.

Test all payment methods.

Place test orders.

Check the courier integration.

Confirm capacity with logistics partners.

Prepare promotional materials and backup options.

Check email authentication and deliverability.

The final week

Do not start major unnecessary technical changes.

Check again:

prices → stock → ads → checkout → payment → delivery → emails → tracking.

Assign someone to monitor the site and campaigns during the peak period.

Set up a procedure for:

  • outage;
  • incorrect price;
  • out of stock;
  • payment issue;
  • broken integration;
  • overload;
  • sudden ad budget depletion.

During the campaign

Do not look only at Ads Manager.

Track the business.

If the ads are performing brilliantly but the warehouse cannot handle another 2,000 orders, increasing the budget is not necessarily the right solution.

Monitor:

  • the server;
  • orders;
  • stock levels;
  • ad spend;
  • cost per acquisition;
  • payment failures;
  • checkout errors;
  • courier flow;
  • questions to WEBSITE.

Black Friday requires operational decisions in real time.

And what do we do after Black Friday?

This is where the part many stores miss begins.

If you used a big discount to acquire a new customer, the job does not end when the order ships.

The following weeks are the time to build a relationship.

Not with endless promo codes.

But with:

  • useful information about the purchased product;
  • relevant complementary offers;
  • a replenishment reminder, where it makes sense;
  • new products;
  • a loyalty program;
  • personalized offers based on the actual purchase.

This is exactly where Black Friday can turn from a campaign for cheap sales in a campaign to acquire valuable customers.

Black Friday is not won on November 27

On the day of the campaign, it is already too late to decide whether you stocked enough of the most in-demand products.

It’s too late to find out that the server can’t handle it.

It’s too late to negotiate an advertising budget.

And it’s definitely too late to discover that the order processing and delivery process can’t handle the volume.

Black Friday 2026 needs to be prepared early, but executed in a focused way.

Build the offer so it truly stands out from your usual promotions.

Secure the inventory.

Secure the infrastructure.

Secure the logistics.

Secure the budget.

And before the first ad runs, decide what you will do with the customer after Black Friday is over.

Because the most valuable order on November 27 may not be the one with the highest profit on the day of the sale, but the one that marks the start of a long-term relationship with a new customer.

Frequently asked questions about Black Friday 2026

When is Black Friday in 2026?

Black Friday is on November 27, 2026. For online stores, operational preparation should start 8-12 weeks in advance.

When should preparation begin?

The offer, budget, stock levels, and technical capacity should be planned as early as September. By the end of October, the price history is already important for announcing the discount.

How is the previous price determined for a discount?

According to the CPC, the previous price is the lowest price applied during a period of no less than 30 days before the discount.

What should be tested in the online store?

Check search, filters, product variants, cart, checkout process, payments, emails, stock levels, courier integrations, and ad tracking. Also run a realistic load test under increased traffic.

When does a seasonality adjustment in Google Ads make sense?

Only when you expect a large and short-term change in conversion rate. Google defines adjustments as most appropriate for events lasting 1 to 7 days.

What should we measure after the campaign?

In addition to revenue and ROAS, track the share of new customers, acquisition cost, profit after variable costs, returned orders, repeat purchases, and customer value after the campaign.
