Black Friday 2026: five things to check in your online store before the traffic arrives
Geir Halvorsen
Senior SEO Specialist
Black Friday starts soon, and for many online retailers Black Week is the most important sales week of the year. This is not the time to build something new. It is the time to make sure that what you already have holds up when traffic multiplies.
These are the five areas we go through with our clients before every campaign peak. Each one can be checked off in an afternoon, and they all come down to the same thing: not losing sales you have already paid to win.

1. Performance: will the site hold up when traffic multiplies?
A slow site costs the most exactly when the most visitors arrive. Every extra second of load time on mobile shows up in your conversion rate, and during Black Week shoppers have little patience.
Core Web Vitals on the right pages. Run PageSpeed Insights on the home page, the campaign page, a category page and a product page, and look at the mobile results. Focus on LCP (how quickly the main content appears) and INP (how quickly the page responds to clicks).
Images and third-party scripts. Campaign banners are often uploaded at full resolution. Compress them, and review chat widgets, pop-ups and tracking pixels added during the autumn.
Load and caching. Ask your hosting or platform provider how much traffic you can handle and whether CDN and caching are set up for the campaign pages. A simple load test tells you more than a guarantee.
Code freeze. Agree on a freeze period, for example from 20 November to 1 December, when no new releases go out. It reduces the risk of something breaking in the middle of the campaign.

2. Checkout, payment and shipping: can customers actually buy?
All the work that goes into driving traffic is wasted if customers get stuck at checkout. Place real test orders instead of assuming everything works.
Test orders in every flow. Buy on mobile and desktop, as a logged-in customer and as a guest, with every payment method you offer and with a discount code.
Payment and shipping providers. Ask whether they have capacity limits or planned maintenance during Black Week, and make sure you have a contact if something goes down.
Delivery times and Christmas cut-offs. Show realistic delivery times, and the last order date for delivery before Christmas, clearly on the product page and at checkout.
Confirmations and customer service. Check that order confirmations and shipping emails go out, and that customer service has ready answers to the most common questions about returns, exchanges and gift receipts.

3. Campaign pages and SEO: can Google and your customers find them?
A campaign page published the day before rarely has time to rank. A permanent page reused every year, on the other hand, builds authority over time.
One permanent URL. Use, for example, /black-friday every year instead of /black-friday-2026. Keep the page live between campaigns with a short text and a newsletter sign-up.
Indexing. Check that the page has no noindex tag, is included in the sitemap and is linked from the home page and the menu. Request indexing in Google Search Console.
Title, meta description and content. Write a title that includes "Black Friday" and what you sell, and give the page some real text, not just a product grid.
When the offers end. Plan what happens after the campaign. Sold-out products should not return a 404, and temporary landing pages should redirect to a relevant page.
4. Tracking and measurement: will you be able to see what worked?
The most expensive advertising week of the year is also the week when broken tracking costs the most. It affects both how you allocate budget and what Google Ads and Meta optimise for.
Purchases show up in GA4. Place a test order and check that the purchase event comes through with the correct revenue, tax and currency, and without duplicates.
Conversions in the ad platforms. Make sure Google Ads and Meta receive purchases and that Consent Mode v2 is set up correctly.
Campaign tagging. Use UTM tags in newsletters, text messages and social media posts so you can tell the channels apart afterwards.
Budget and bidding strategy. Plan a budget increase in good time and consider a seasonality adjustment in Google Ads, so that automated bidding does not overreact before and after the campaign.

5. Prices, stock and campaign rules: is what customers see correct?
A wrong price or a product that is out of stock costs you both sales and trust. Misleading price comparisons can also become a matter for consumer authorities.
Lowest price in the last 30 days. Under EU price indication rules, which in Sweden are set out in the Price Information Act, a price reduction must be compared with the lowest price the product has had in the last 30 days, before the sale started. Check that your platform calculates and displays the reference price correctly, and avoid raising prices just before the campaign.
Campaign rules in the platform. Test that discounts, bundle prices and discount codes work together as intended, and that they start and end at the right minute.
Real-time stock levels. Make sure stock is synced between your ERP, your e-commerce platform and any marketplaces, so you never sell the same item twice.
Product feeds. Check that Google Merchant Center and other feeds show the campaign price with the right dates and that no products have been disapproved.
After the campaign
Black Friday is won before it starts
Black Friday is rarely won by what you build in the final week, but by making sure what you already have works. Go through the five checks, assign responsibilities and decide who is on hand during the campaign days if something goes wrong.
When the campaign is over, save the numbers. The best input for Black Friday 2027 is what you measure this year, and it is also a good starting point for conversion rate optimisation for the rest of the year.
