Black Friday stopped being an American curiosity years ago — for Australian retailers it’s now the biggest online trading weekend of the year, and if you run a store, you’re probably already planning the sale: the discounts, the email, maybe some ad spend to bring people in.
So let me ask the question that, in my experience, almost nobody asks until it’s too late: when the traffic arrives, can your website actually take the money?
Because here’s the maths nobody puts in the marketing plan. You’ll pay — in ad dollars, email effort or both — to send a crowd toward your shop. If the door sticks, you paid for the crowd and your competitor got the sales. A slow product page, a checkout that fumbles on a phone, a site that buckles under load: on an ordinary Tuesday these leak revenue quietly. On Black Friday, they leak it at the year’s fastest rate, at the exact moment you’ve spent money accelerating the flow.
The good news: readiness is a checklist, not a mystery. Here’s ours — run it a couple of weeks out, while everything is still calmly fixable. Not the night before.
1. Speed — because sale shoppers are the least patient humans alive
Your Black Friday visitor has fourteen tabs open and a list. The evidence on what impatience costs is unambiguous: Google found the probability a visitor bounces rises 32% as a mobile page’s load goes from 1 to 3 seconds, and 123% from 1 to 10 seconds (Google/SOASTA, 2017).
And the prize for getting it right is startlingly concrete: a Google/Deloitte study found a 0.1-second improvement in mobile load time lifted retail conversions by 8.4% and average order value by 9.2% (Google + Deloitte, 2020). A tenth of a second. On your biggest weekend, those tenths are dollars with your name on them.
Do now: compress and properly size your product images (the number-one culprit, as always), confirm caching is actually on, and run your key pages through Google PageSpeed Insights — the mobile score, not the flattering desktop one. A site that’s sluggish when quiet will be worse under sale-day load.
2. Mobile — where the buying actually happens
Picture your actual Black Friday customer: on the couch, phone in hand, half-watching something. Worldwide, mobile is 50.29% of web traffic (Statcounter, May 2026) — and impulse-friendly sale shopping skews harder still.
Do now: walk your own store on your phone, on mobile data, as a customer. Product page → add to cart → checkout → pay. Every tap that’s fiddly, every field that fights autofill, every step that makes you squint is a place where real money will silently exit the queue. Most lost mobile sales die in the checkout, one small annoyance at a time.
3. Test the full checkout — with real money
This is the step that feels like overkill until the year it saves you. Place a genuine order on your own store, end to end: add to cart, apply the actual discount code you’ll be running, pay with a real card, and confirm that (a) the order appears, (b) you get notified, and (c) the customer confirmation email arrives — and not in spam.
Every November, somewhere out there, a store discovers mid-sale that its payment gateway or order emails broke months ago. Nobody noticed, because nobody tested. Five minutes and a refunded test order buys you certainty; skip it and you’re gambling the year’s biggest weekend on “it worked last time I looked.”
4. Make sure the hosting can take a crowd
A traffic spike is a load test you didn’t schedule — and cheap shared hosting fails it with legendary timing, because every other store on that crowded server is having their biggest weekend at exactly the same moment. Everyone’s peak lands together; the server carries none of them well.
Do now: if you’re expecting real volume, ask whoever manages your hosting one plain question: “will this handle several times normal traffic on the last weekend of November?” Good caching and a CDN do a lot of the heavy lifting here — they mean most visitors get served fast without hammering the server at all. If the honest answer is a shrug, you want to know that now, in calm weather, while moving is still an option.
5. Make the offer unmissable — and the store trustworthy
Traffic and speed get shoppers in; clarity and trust get them to pay:
- Say the deal plainly — a banner with the offer and its end time, on every page, not buried in a news post.
- One obvious call to action per page, working, tested.
- Trust signals near the checkout: genuine reviews, secure-payment marks, and your shipping and returns info where a hesitant first-time buyer can find them. Black Friday brings you strangers; strangers need reasons to trust you with their card, and they need them at the moment of doubt, not on a policy page three menus deep.
6. Have a plan for when something breaks anyway
Even well-prepared stores have moments. The difference between a hiccup and a catastrophe is entirely in the preparation: know who you’ll call if something breaks on the Friday night (and whether they answer things on Friday nights), have a fresh backup taken before the weekend, and keep your hosting login somewhere findable by a stressed person. Five minutes of “what if” beats an hour of panicked password resets while the ads keep running.
The week-before checklist
- [ ] Key pages load fast on a phone, on mobile data
- [ ] Full checkout tested with a real payment, both confirmation emails received
- [ ] The actual discount codes tested
- [ ] Hosting confirmed for spike traffic; caching/CDN on
- [ ] Offer visible everywhere, with an end time; CTAs tested
- [ ] Reviews, payment marks, shipping/returns visible near checkout
- [ ] Fresh backup taken; emergency contact and logins written down
Print it, stick it near the monitor, and do the honest thing with each box.
If reading this gave you a small knot in the stomach about your own store — good, that’s the useful kind, and there’s still time to act on it. We run pre-sale readiness checks for exactly this: speed, mobile, checkout, hosting, in plain English, fixed before the rush rather than diagnosed during it. We’re in Campbelltown and we’d genuinely rather you caught it now than lost your best weekend to a wobbly checkout.
