Each year, Black Friday triggers a buying frenzy across the United Kingdom and Europe. What was once a US import has now become a cornerstone of the global e-commerce calendar. And for good reason: according to Enov (2023), 61% of year-end e-commerce sales took place during Black Friday. Impressive, isn’t it?

In other words, if you run an online shop, ignoring Black Friday is like leaving money on the table. But diving head-first into a discount war can quickly turn into a disaster for your margins and your brand image.

The goal isn’t merely to sell more, but to sell better: to create a consistent customer experience, to execute a well-oiled marketing campaign, and, crucially, to retain new buyers once the rush is over.

Let’s see exactly how to prepare for a successful and sustainable Black Friday.

✅ Key Takeaways

  • Black Friday remains the biggest driver of eCommerce sales in the UK.
  • Prepare early, with a clear strategy and measurable objectives.
  • Create value without destroying your margins: double up on referrals and points.
  • Activate your customer ambassadors to boost your reach.
  • Build loyalty immediately after purchase to maximise ROI.

Why take part in Black Friday?

Black Friday has become an unmissable event in France and across Europe. In 2023, 61% of online sales were made during this period (Enov, 2023). That’s colossal—and the figure continues to rise every year, proof that consumers now expect this shopping moment.

So why should you join in?

Firstly, it’s the peak shopping period before Christmas. Black Friday marks the start of the promotional season. Your customers are already in a buying mindset: you don’t need to convince them, only to be in the right place at the right time.

Secondly, it’s a powerful customer acquisition lever. Giants like Amazon, Apple and FNAC attract millions of visitors—but many consumers are also eager to discover smaller, more transparent and human-centred brands. By offering a seamless experience, responsive support, and clever loyalty rewards, you can turn one-time buyers into long-term customers.

Finally, a well-prepared Black Friday isn’t just a “price war”. It’s a strategic opportunity to strengthen relationships, raise brand awareness, and create a memorable post-purchase experience.

9 Steps to Prepare for Black Friday

There's no such thing as a successful Black Friday without a real plan of attack.

It's not enough to display -30% on a banner to boost your sales.

Preparing for this period is above all about making the right choices... in the right order.

So here are the key steps you need to take if you want to perform (and not just survive) during Black Friday.

1. Set Clear Objectives and KPIs

Before launching any campaign, define your goals. What are you aiming for?

  • Increase revenue?
  • Acquire X new customers?
  • Improve your Average Order Value (AOV)?
  • Boost your conversion rate?

Set measurable KPIs. Without them, you can’t assess performance or calculate the true profitability of your Black Friday campaign.

2. Analyse Past Performance

If you’ve run Black Friday campaigns before, review everything: sales, AOV, best-selling products, top channels, email open rates, etc.
If not, look at your seasonal peaks (Christmas, sales, back-to-school). These insights will help shape your offers and marketing actions.

3. Select the Right Products and Build Smart Offers

Don’t slash prices across the board—Black Friday is about balance.
Focus your offers on:

  • your best-sellers (volume effect);
  • high-margin products that can bear a discount;
  • new releases you want to promote.

The aim isn’t to “cut everything”, but to create perceived value.
Offer exclusive benefits—loyalty points, early access, or premium delivery—instead of extreme discounts. Stay competitive without eroding your margins.

4. Check Your Stock and Logistics

The ultimate Black Friday nightmare? Running out of stock.

Audit everything: inventory, lead times, carriers, customer service, returns management. Anticipate surges and test your website’s capacity (speed, server load, payments).
A slow site or a buggy checkout = lost sales.

5. Optimise Your E-commerce Website

Your website must be flawless.

  • Create a dedicated Black Friday landing page.
  • Test the mobile experience (70% of purchases happen on smartphones).
  • Display discounts and offer durations clearly (a legal requirement in France).
  • Add a countdown timer to create urgency.
  • Simplify checkout—fewer steps, more conversions.

Ensure a smooth, fast, and consistent experience across emails, ads, and site.

6. Plan Your Communication and Teasing Strategy

The key to Black Friday success? Anticipation.

Start teasing two to three weeks before the big day.

Examples:

  • A “Save the Date” email series.
  • Countdown posts on social media.
  • VIP pre-registration for early access.

You can even be transparent: announce your dates and philosophy (“no fake discounts, just real rewards”). This builds trust and credibility.

7. Prepare Your Advertising Campaigns

Advertising costs skyrocket in late November. Plan your budgets and creatives early.

  • Launch Facebook and Google Ads from early November.
  • Use retargeting for recent visitors.
  • Build lookalike audiences from your best customers.
  • Schedule campaigns for strategic hours (morning, lunch, evening).
  • Track performance in real time and adjust bids accordingly.

8. Monitor and Adapt in Real Time

During the Black Friday weekend, go into command-centre mode:

  • Track sales hourly.
  • Monitor conversions, cart abandonment, and traffic.
  • Be responsive on live chat, email, and social media.
  • Adjust offers as needed.
  • Recover abandoned carts with personalised reminders:
    “Still hesitating? Enjoy an extra 10% off if you complete your order before midnight.”

9. Conduct a Post-Campaign Review

Once the storm passes, analyse calmly:

  • Which channels performed best?
  • Which offers drove the most profit?
  • How many new customers made repeat purchases?

These insights will inform your CRM strategy and future retention campaigns.


5 Effective Black Friday Tactics for E-commerce

Here’s where you can truly stand out. Instead of competing on price, create value.

1. Double Referral Rewards

During Black Friday, increase your referral rewards to make the gesture more appealing.
If your usual reward is £10 for both referrer and referee, temporarily raise it to £20 each.
A simple, high-impact move that fuels organic acquisition without blowing your ad budget.

2. Double Loyalty Points

Rather than giving direct discounts, offer double points on selected products or orders above a certain threshold.
Example: instead of 1 point per £1, offer 2 points throughout the weekend.
Customers feel they’re getting a good deal—while earning future rewards.
A healthy alternative to discount warfare.

3. Reward Nano-Influencers

Identify your brand advocates (small but engaged audiences) and reward them with points or perks when they post during Black Friday.
Result: more organic reach, authentic UGC, and a stronger brand image.

4. Exclusive Offers for VIP Members

Build a sense of belonging: early access, private sales, or double loyalty points.
It nurtures loyalty and reduces reliance on paid advertising.

5. Post-Purchase UGC & Reviews

Encourage buyers to leave reviews, share unboxing videos, or post about their experience.
Reward them with points or vouchers.
Authentic user content boosts credibility and feeds your CRM.

How to Retain Customers After Black Friday

Most brands treat Black Friday as an ending—but it should be the beginning of a long-term relationship. If you go silent on Monday, you waste your acquisition efforts. Here’s how to build ongoing engagement.

1. Offer a Time-Limited Voucher

Example: after a purchase on 29 November, send a £10 voucher valid until 31 December.
Message: “Enjoyed your first experience? Come back before Christmas—it’s on us.”
Encourages repeat purchases and improves your Repeat Purchase Rate.

2. Remind Customers of Unused Points or Bonuses

Send a gentle reminder:
“Still have 150 points left… why not use them before the end of the month?
Such emails can generate up to 20% more repeat sales without sounding pushy.

3. Bonus Points for a Second Purchase

Create a clear incentive:
Make a second purchase before 5 January and earn double points!
Boosts purchase frequency and strengthens loyalty.

4. Suggest Complementary Products

Offer relevant add-ons: a scarf with a coat, headphones with a smartphone.
Encourage repeat orders and raise AOV through smart recommendations and bonus rewards.

5. Launch Post-Purchase Missions

Empower customers to become part of your brand story:

  • Leave a review
  • Share an unboxing post
  • Post a testimonial

Reward them with points, vouchers, or gifts. These actions fuel trust and community engagement.

6. Automate CRM Workflows

Set up automated sequences:

  • Thank-you emails + bonus points
  • Reminders before voucher expiry
  • “New collection” emails based on purchase history

Automation ensures consistency without overloading your marketing team.

7. Create a “Black Friday Alumni” Club

Transform Black Friday buyers into members of an exclusive club: early access, extra rewards, or private offers.
It’s a clever way to build loyalty and capitalise on the event long after it ends.

7 Common Mistakes That Can Ruin Your Black Friday

Preparing for Black Friday requires discipline and foresight. Even the best offers or campaigns can collapse under the weight of a few classic missteps.
Here are the seven most frequent ones — and, more importantly, how to avoid them.

1. Discounting Without Strategy

This is by far the most common mistake. Many brands panic and launch huge promotions — sometimes as deep as 70% off — without properly calculating their margins.
The result? A surge in sales volume, but a dramatic drop in profitability.

Black Friday was never meant to be a clearance sale. Its purpose is to stimulate purchases, attract new customers, and build perceived value.

👉 Replace blunt price cuts with smarter mechanisms, such as:

  • enhanced loyalty points on selected products;
  • a temporarily more generous referral reward;
  • or a free gift added to the basket.

These levers strengthen your margins and your relationship with customers. They help you escape the vicious circle of “discounts for the sake of discounts”.

2. Neglecting Technical Performance

A slow website or a failed payment process is every retailer’s worst nightmare.
You’ve paid for ads, attracted visitors — and then everything collapses at checkout.

Before the big day, carry out a technical stress test on your website:

  • simulate several hundred simultaneous connections;
  • check loading times on key pages (homepage, product, basket, checkout);
  • test all your payment integrations (Stripe, PayPal, Apple Pay, etc.).

Make sure your site is fully mobile-friendly, since around 70% of Black Friday purchases are made on smartphones.

Finally, have a technical backup plan: a secondary server, a visible support number, and clear error messages.
A fast, stable website isn’t just an asset — it’s a competitive advantage.

3. Promising Misleading Discounts

The infamous “Up to 80% off” that applies to a single product? Those days are over.
In 2025, consumers are better informed, more demanding, and far more sceptical.
A poorly worded or misleading promotion can destroy your credibility and damage your future campaigns.

Be transparent with your offers:

  • Display the average actual discount, not the maximum.
  • Specify the products included (“Up to 30% off across 150 items”).
  • Avoid endless asterisks and vague conditions.

In short: an honest 25% discount, clearly explained, is worth far more than a fake 70% that disappoints.
Trust is a far more valuable marketing asset than one extra click.

4. Ignoring Customer Service

Black Friday also brings an avalanche of messages, calls, and return requests.
If your customer service team isn’t ready, chaos is never far away — and a frustrated customer in November is a lost customer for life.

A few key habits:

  • Temporarily reinforce your customer support team (or outsource to a specialist).
  • Set up a live chat function on your website.
  • Prepare automated replies for FAQs (“Where is my parcel?”, “Can I change my order?”).
  • Shorten response times during the critical period.

And above all: train your team well.
A clear, empathetic, and timely response can turn a complaint into a positive review — and even word-of-mouth promotion.

5. Failing to Plan a Retention Strategy

Black Friday attracts, but rarely retains — unless you plan for it.
Too many brands stop at “Thank you for your order”.
Big mistake: without a post-purchase plan, you’ll lose up to 70% of new customers before Christmas.

Even before launching your offers, prepare your post–Black Friday CRM strategy:

  • a personalised thank-you email;
  • a voucher valid for a few days after the first order;
  • bonus loyalty points for a second purchase;
  • a “Did you enjoy your product?” message to encourage reviews.

This extends the life of your campaign and feeds your CRM with valuable data.
The real ROI of Black Friday lies not in your average basket value, but in customer retention.

6. Competing on Price Alone

You’ll never beat Amazon or FNAC on pure discounting — and that’s perfectly fine.
Their power lies in logistics and scale. Yours lies in brand, proximity, and customer experience.

Consumers today aren’t just chasing “the best deal”; they want to buy from brands that reflect their values.

Focus instead on:

  • an authentic brand story;
  • a distinctive loyalty programme;
  • and emotionally resonant communication — your tone, values, and commitments.

Price grabs attention, but perceived value builds loyalty.

7. Failing to Segment Your Audiences

The final mistake — and perhaps the most costly. Sending the same offer to your entire mailing list or Meta Ads audience is the fastest way to burn your budget.

Segment your audiences based on:

  • level of engagement (active, dormant, new customers);
  • customer lifetime value (CLTV);
  • type of products purchased;
  • or acquisition channel (ads, referrals, SEO, etc.).

This allows you to tailor your messaging:

  • New customers: “Welcome to the community — discover our best-sellers.”
  • Loyal customers: “Your loyalty deserves a special thank-you.”
  • Inactive users: “We’ve saved an exclusive surprise just for your comeback.”

Targeted communication can double or even triple conversion rates, while reducing marketing fatigue.

Segmentation isn’t just a tactic — it’s the key to sustainable growth.

Black Friday vs Cyber Monday

Black Friday and Cyber Monday serve complementary purposes.
Black Friday creates urgency and volume; Cyber Monday targets hesitant or late buyers.
The latter is perfect for clearing stock, recovering abandoned baskets, or offering online exclusives (e.g., free delivery, bonus points).

Combined, they form a powerful two-phase campaign:
Black Friday attracts; Cyber Monday retains.
Between the two, keep engagement alive through reminders and countdowns—simple tactics that can add 15% more sales.

Black Friday vs. Cyber Monday: which one should you focus on?

Black Friday and Cyber Monday serve two complementary purposes.
Friday is all about frenzy — it drives massive traffic and creates excitement. It’s the moment for headline offers, high volumes, and customer acquisition.
Monday, by contrast, is more digital and deliberate: the perfect time to recover abandoned baskets, clear remaining stock, or offer online exclusives such as free delivery, bonus loyalty points, or complimentary accessories.

By combining the two, you build a two-phase campaign:
Black Friday attracts; Cyber Monday retains.

Between the two, keep the momentum going with follow-up emails, social media stories, and countdowns like “24 hours left to enjoy Cyber Monday”.
This simple reminder alone can generate up to 15% additional sales.

In short, think of them not as separate events, but as a single, continuous customer journey:
a powerful Black Friday followed by a smart Cyber Monday — the perfect way to make the most of the season’s potential without exhausting your margins or your team.

To prepare effectively for Black Friday, set clear objectives, anticipate your logistics, design high-value offers (referrals, loyalty programmes, UGC), and plan a post-purchase follow-up to turn new customers into loyal ones.

At Loyoly, we help e-commerce brands go beyond simple promotions.
The secret? Turning every Black Friday buyer into a loyal ambassador through personalised post-purchase journeys, smart referral systems, and engaging loyalty mechanics.

Because true Black Friday success isn’t measured on the Friday itself — it’s the one that lasts through January and beyond.
