Black Friday 2026 falls on Friday 27 November, with Cyber Monday on 30 November. For many online stores, these days bring more traffic and orders than any other week of the year. It is also when stores crash, checkouts fail and tracking breaks, exactly when every minute costs money.
Use this checklist to prepare your store, servers, marketing and team. Start now: the closer you get to the date, the riskier every change becomes.
Timeline at a glance
| When | Focus |
|---|---|
| 4+ weeks before | Performance, load testing, platform and plugin updates, security patches |
| 3 weeks before | Promotions set up, email flows, tracking checks, stock planning |
| 2 weeks before | Final testing, support preparation, code freeze starts |
| 1 week before | Monitoring, war room plan, backups verified |
| Black Friday to Cyber Monday | Monitor, respond, no risky changes |
| Week after | Analyse, fix, review |
1. Performance and infrastructure
- Load test your store with realistic traffic, including add-to-cart and checkout (see how to load test your store)
- Check page caching hit rates (Varnish, CDN, plugin cache)
- Make sure cart and checkout are fast under load, since they cannot be fully cached
- Scale up servers or plan auto-scaling; ask your host about peak capacity
- Check database performance and slow queries
- Put a CDN in front of images and static files
- Remove or delay heavy third-party scripts
- Check Core Web Vitals on mobile (see Core Web Vitals for e-commerce)
Platform-specific guides: slow Magento 2, speed up WooCommerce, Shopify speed optimisation.
2. Security and updates
- Apply platform, plugin and PHP security updates now, not during peak week. Critical runtime issues like PHP2Shell need patching before you freeze
- Check admin accounts and 2FA
- Review scripts on checkout pages (skimming attacks peak when traffic is high, see the e-commerce security checklist)
- Enable bot protection and rate limits against card testing and inventory scraping
3. Code freeze
Decide a code freeze date, typically one to two weeks before Black Friday. After that date:
- No new features, theme changes or plugin updates
- Only critical fixes, tested on staging, approved by one responsible person
This single rule prevents more peak-season outages than anything else.
4. Backups and rollback
- Verify backups run and test a restore (see 3-2-1 backup strategy)
- Know how to roll back the last deployment quickly
- Have your hosting and developer contacts ready
5. Promotions and pricing
- Set up discounts and scheduled price changes in advance, and test them on staging
- Test coupon combinations: can customers stack discounts you did not intend?
- Check prices including VAT and the correct display of strike-through prices. In the EU, the Omnibus rules require that the reference price for a discount is the lowest price of the previous 30 days
- Prepare landing pages and banners early
- Update your Merchant Center feed with sale prices (see Merchant Center fixes)
6. Checkout and payments
- Test every payment method with real test orders
- Check payment provider capacity and status pages
- Have a backup payment method enabled
- Check shipping rates, free shipping thresholds and delivery promises
- Test order confirmation emails
7. Stock and fulfilment
- Sync stock frequently to avoid overselling
- Plan warehouse capacity and extra staff
- Communicate realistic delivery times on product pages
- Prepare for higher return volumes in December
8. Tracking and analytics
- Check GA4 purchase events match shop orders (see GA4 missing conversions)
- Check Google Ads and Meta conversions
- Verify Consent Mode works (see Consent Mode v2)
- Prepare a simple real-time dashboard: orders, revenue, conversion rate, errors
9. Email and marketing
- Grow your email list in the weeks before with an early-access signup
- Schedule campaigns: teaser, launch, reminders, last chance, Cyber Monday
- Warm up sending volume if you will send much more than usual
- Check abandoned cart and browse abandonment flows are active (see 10 email flows)
- Coordinate ad budgets and bid strategies with promotions
10. Customer support
- Update FAQs: delivery times, returns, Black Friday conditions
- Prepare reply templates for common questions
- Use an AI assistant for order status and FAQ questions to handle peak volume (see AI customer support)
- Plan extra support capacity and opening hours
11. Monitoring and war room
- Uptime monitoring with alerts to phone
- Error rate and server resource alerts
- Checkout success rate and payment failures
- Agree who is on call, how to reach them and who decides
- Prepare a maintenance page, just in case
After Black Friday
- Compare results with last year: traffic, conversion rate, average order value, revenue
- List what broke or was slow, and fix it in January
- Check customer feedback and reviews
- Clean up temporary promotions and scripts
Frequently asked questions
When should I start preparing for Black Friday?
Ideally six to eight weeks before. If you are starting late, focus on performance, checkout testing, backups and a code freeze.
Should I update plugins right before Black Friday?
Apply security updates as early as possible, then freeze. Avoid feature updates in the last two weeks unless they fix a critical issue.
How much extra traffic should I plan for?
Use your own data from previous years and campaigns, and test with a safety margin above your expected peak.
