Black Friday lands on 27 November this year. If your plan still includes launching a new A/B test, it is time to drop it.
A clean test needs two to three weeks of normal traffic. Count back from the 27th and the last clean window closed around 6 November. Anything you launch now will read on holiday traffic, which behaves nothing like the rest of the year, and you will roll out a "winner" that was really just a different crowd.
The scale makes this worth getting right. Cyber Week 2025 did $44.2 billion online in the US, with Cyber Monday a record $14.25 billion (Adobe, December 2025). Shopify merchants alone took $14.6 billion and peaked at $5.1 million a minute on Black Friday (Shopify, December 2025). Nobody ships a test at that speed.
What you can still do in the next two weeks
Lock the offer. Decide the discount, the free-shipping threshold and any bundles now, and put them on every ad, landing page and email the same way. Mismatched offers between ad and page are the most expensive mistake of the week.
Check mobile like a customer. 57.5% of Cyber Monday sales came from a phone (Adobe). Place a real order on your own phone, with a discount code, on mobile data. Note every moment you hesitate.
Add a post-purchase offer. Traffic costs more that week, so every order should carry more margin. A one-click add-on after checkout does not touch conversion rate and lifts order value.
Load test the slow parts. Apps, review widgets and pop-ups that are fine at normal volume can drag when traffic jumps three to five times.
Then freeze the site. No theme edits, no new apps, no "quick tweaks" from 20 November until the week is over.
After the week
Write down what broke, what sold out and which offer carried the week. That list is next year's October plan.
Parah Group keeps a full Black Friday conversion checklist covering offer, cart, checkout and the code freeze, built from the six-week BFCM program they run for DTC brands on Shopify.
