It's lunchtime on Friday 27 November 2026. Your best Shopping campaign has spent its daily budget, the evening traffic hasn't started yet, and you're staring at conversion data you don't trust. You can't tell if you should raise the budget, cut it, or leave it alone, because the numbers behind the decision may be wrong.
That's how Black Friday usually goes wrong for UK ecommerce teams. It isn't one dramatic failure. It's broken tracking, a feed showing yesterday's price, and a budget set for an average Friday hitting a peak it was never sized for. All three are fixable in three weeks. None is reliably fixable on the morning itself, when approvals, recrawls and learning periods eat the hours you need for trading.
This Black Friday Google Ads checklist puts eight checks in the order I'd do them. Measurement and feed accuracy come first, because every budget and bidding decision sits on top of them. Then budgets, bidding, promotion assets, audiences, landing pages and checkout. It finishes with timing, because demand builds in the 10 days before the sale, not just on the day, and Cyber Monday follows on Monday 30 November.
1. Confirm Tracking Fires Correctly and Records Purchase Values
Start with a test order, not a budget change. A site release, new payment option or consent banner update can interrupt a purchase tag. If Google Ads receives a faulty signal, smart bidding can optimise towards the wrong outcome, making any later budget decision less reliable.
Place a real test order with a real card, then refund it. Confirm the purchase conversion fires once per order on the confirmation page and that its recorded value matches the order total. If checkout uses a separate domain or a hosted payment gateway, check that cross-domain tracking carries the session through to the thank-you page.

What to Verify Before You Touch Budgets
- Count setting: Set purchases to count every conversion. Refresh the confirmation page to check for duplicate firing, which can inflate revenue and make ROAS look stronger than it is.
- Value rules: Choose whether conversion values include VAT and delivery. Apply that choice consistently in Google Ads, your analytics platform and internal reporting.
- Missing values: Find orders recorded without a value. They can lead value-based bidding to optimise towards zero.
- Enhanced conversions: Check that enhanced conversions are set up and passing hashed data if your consent and privacy setup allows it.
Tracking problems are among the issues that come up frequently when reviewing ecommerce accounts before peak season. Resolve them before changing budgets or bids: otherwise, performance decisions may rely on duplicated, missing or inaccurate purchase data. Use this guide to track conversions correctly and confirm the purchase value is recorded as intended.
2. Make Sure the Product Feed Matches the Website
Google Shopping and Performance Max read your Merchant Center feed, not your website. If the feed shows a different price, stock status or sale price from the live product page, products get disapproved for mismatch and you lose the sale at the exact moment demand peaks. This check decides whether the right products show at the right price.
Availability has to agree everywhere. Google's Merchant Center guidance requires product availability to match the landing page, checkout pages and structured data, using values such as in_stock, out_of_stock, preorder and backorder, with an availability date supplied for preorders and backorders. Checking only the feed export isn't enough.

Price timing needs the same discipline. Use the sale_price attribute with sale_price_effective_date so discounts start and end automatically. Google's price mismatch advice recommends scheduling a feed upload or using the Content API immediately after the website change, and notes that price corrections can take 24 to 48 hours to appear after recrawling. You don't have 48 hours on Black Friday morning.
- Sample your top sellers: Compare feed, product page, checkout and schema markup for every priority SKU.
- Clear diagnostics daily: Work through price and availability mismatch warnings through the sale window.
- Mark sold-out lines out of stock: Don't leave them live to absorb clicks you can't fulfil.
- Refresh titles: Lead with product name and the attributes shoppers search on.
For UK Flat Roofing, we reviewed the shopping feed for best practice in phase one alongside the tracking fix. Our shopping feed optimisation guide sets out the attributes worth checking first.
3. Set Budgets and Pacing for the Spike
Size budgets for the peak day, not the average day. The rule here is simple. Your key campaigns must not run out of budget by lunchtime on 27 November, because campaigns that go dark early miss the evening conversions that often carry the sale.
Look at lost impression share due to budget on your main Shopping, Performance Max and brand campaigns over recent weeks. If a profitable campaign is already losing share to budget on ordinary trading days, it will cap out far earlier when search volume and competition rise together. Use that gap to estimate peak daily budgets campaign by campaign, rather than applying one blanket percentage across the account.

The wider market tells you why selectivity matters. IAB UK's digital adspend figures put UK search advertising at £17.9 billion in 2025, which was 44% of total digital advertising expenditure. You're bidding in a large, contested auction, so extra budget buys more expensive clicks unless it's aimed at products and searches that already convert profitably.
Pacing on the Day
Set the higher budgets for 27 and 30 November in advance and check them in the account the day before. During each day, compare spend by hour against your previous peak, and move budget from weak campaigns to converting ones early rather than at 9pm. Keep a reserve for Cyber Monday. Our PPC budget calculator helps sense-check the daily figures before you commit them.
4. Get Bidding Ready for Promotional Margins and Volume
Set bid strategies before sale week. Smart bidding needs stable data, and a strategy switch or large target change shortly before 27 November can trigger a learning period when you need campaigns to remain steady. Make small, planned adjustments if needed. Avoid structural changes in the final week.
Review target ROAS and target CPA against sale pricing, not full-price trading. Discounts reduce the margin on each order, so an October target may restrict profitable sales or allow unprofitable ones during the promotion. Calculate contribution margin after the discount, delivery and expected returns, then set targets that reflect what the business can afford.
Practical rule: Judge products on retained margin, not headline ROAS. A heavily discounted line with a high return rate can look strong in Google Ads and still lose money.
Use custom labels or a margin-based feed split to prioritise high-margin products and limit spend on lower-margin lines. Set this up before the peak, alongside the earlier checks on tracking and feed accuracy. Changing bids cannot compensate for unreliable purchase values or product information.
Check demand before raising targets or budgets across the board. Marketing Signals' analysis of UK Black Friday search trends reported that UK searches for Black Friday terms were 36% below their 2019 peak in 2025, while deal-related searches fell 40%. When demand softens, competing harder for generic searches can waste spend. Keep brand, generic product and competitor campaigns separate, set a marginal ROAS threshold for each, and increase spend only where the extra conversion value justifies the extra cost. Treat the 10 days before the sale as a period when demand builds, and use performance data to make measured adjustments rather than waiting until sale week.
5. Refresh Promotion Assets and Sale Messaging
Promotion assets tell shoppers about the offer before they click, which qualifies the click and usually improves its quality. They only help if they're approved, correctly dated and identical to what the site shows. An asset promising a discount the landing page doesn't honour costs you the click and the customer's trust.
Set the promotion up in Merchant Center with the right dates, eligible products and any code, then check its approval status a week before the sale. Remember that live, approved, eligible and displayed are four different states. A promotion can be approved but mapped to the wrong products, or mapped correctly but attached to a code that fails at checkout. Test the exact code, on mobile, on an eligible product and an ineligible one.
In Google Ads, add promotion extensions with dates matching the sale exactly, plus callouts and sitelinks pointing to sale category pages rather than the homepage. For Performance Max, refresh asset groups with sale imagery, headlines and descriptions early enough for review. Schedule everything to stop when the sale ends, so nothing runs on into December promising an offer that no longer exists. Our walkthrough of promotion extensions covers the setup fields in order.
Keep price claims genuine. Under UK pricing rules, a "was" price needs to reflect a price the product was offered at, so check the claim against your own price history before it goes into an ad. Watch the distinction between a reduced product price and a checkout promotion too. If the discount is already in the sale_price, don't present the same saving again as an extra code at checkout.
Also allow for feed approvals if you're launching new promotional lines. Google's Demand Gen product feed guidance states that new product feeds can take up to three days to be approved. A replacement feed submitted on 25 November may not be serving when you need it.
6. Refresh Audience Lists and Set Exclusions
People who already know your brand convert differently during a sale, and audience lists are how you bid for them differently. Refresh Customer Match uploads now, then check list sizes and match rates in Audience Manager. A list that's too small to serve, or still processing on 26 November, gives you nothing to bid on.
Build or update separate lists for past purchasers, cart abandoners, recent site visitors and high-value customers. Each group needs different treatment. Say you're running prospecting Performance Max for new customers. Excluding people who bought in the last few weeks stops acquisition budget chasing someone who has just ordered the same product and frees that spend for new shoppers.
Decisions to Make Before Sale Week
- Dedicated campaigns or bid adjustments: Cart abandoners often justify their own remarketing campaign with sale-specific messaging and a protected budget.
- High-value customers: Give them a separate list so you can bid up for proven spenders without lifting bids across all returning traffic.
- Overlap control: Check that lists feeding audience signals don't overlap so heavily that you can't tell which group is driving performance.
- Exclusion windows: Set the recent purchaser window to match your real repurchase cycle, not a default.
Handle the data properly. Confirm you have consent for remarketing and customer uploads, that uploads comply with UK GDPR, and that hashed data is formatted correctly before you rely on the match rate. Do this admin in week one. Consent questions raised on 26 November tend to stay unanswered until the sale is over.
7. Check Landing Pages and Checkout Speed
Peak traffic is the most expensive traffic you'll buy this year, and it's wasted if the page is slow or the offer is hidden. Open your sale landing pages, key category pages and top product templates on a real phone. The sale price, original price, offer terms and delivery cost should be visible without scrolling, and they must match the feed and the ads exactly.
Run PageSpeed Insights or Lighthouse on the homepage, a category page, a product page and the checkout. Fix the biggest issues first, which are usually oversized unoptimised images and slow third-party scripts, rather than chasing small score gains across every template. Then complete the full checkout yourself, including guest checkout and express payment options such as Apple Pay and Google Pay on both iOS and Android where you offer them.
The video below walks through diagnosing why product ads and their landing pages underperform, which is worth working through against your own sale pages.
Say your mobile product template shows the full price first and the discounted price below the fold. Shoppers arriving from a Shopping ad showing the sale price see an apparent mismatch and leave. Moving the sale price up fixes a problem no bid change can solve. The same applies to a forced account creation step before payment. Find it in a test order now and remove it, rather than reading about it in your abandonment data afterwards.
Post-purchase detail belongs on these pages too. Ecommerce News UK's reporting on Black Friday returns noted returns volumes rising by around 80% in the first week of December after Black Friday promotions. State delivery cut-offs, dispatch times, stock messages and return conditions clearly before checkout. Clear terms won't eliminate returns, but unclear terms generate avoidable ones, plus support contacts your team doesn't have time for. Finally, confirm with whoever hosts the site that it can handle peak load, and test that claim before the event if you can.
8. Start Early Because Demand Builds in the 10 Days Before
Black Friday demand builds before the sale opens. In the 10 days beforehand, shoppers compare prices, sign up for early access and decide where to buy. If your first activity starts in sale week, you miss that research period and spend at peak prices introducing your offer. Plan the work across three weeks, starting with measurement and feed accuracy before changing budgets or bids.
Online sales account for over a quarter of UK retail sales. The Office for National Statistics retail sales bulletin covers retail sales in November 2025 and explains how Black Friday timing can affect monthly reporting. Compare equivalent promotional periods rather than calendar months. Split results into pre-sale, Black Friday, Cyber Monday and post-event periods to see where budget worked.
A Three-Week Timeline That Fits the Dates
- From around 6 November: Check tracking and feed accuracy first. Then agree sale prices, margins and peak budgets, and prepare bidding. Give each checklist item a named owner and deadline.
- By around 17 November: Launch pre-sale campaigns, remarketing and approved promotion assets. Test pacing against a normal trading week, and check landing pages and mobile checkout.
- 27 to 30 November: Monitor performance hourly and reallocate budget early in the day. Avoid large structural changes during the sale, and keep a rollback plan for budgets and bids if something breaks.
Use market benchmarks alongside your own trading history. IMRG's retailer benchmarking draws on more than 220 leading UK retailers representing over £30 billion in online spend, and its Black Friday Tracker covers more than 150 retailers. Record pre-peak baselines for traffic, conversion rate, basket value and checkout abandonment, then review them daily. If traffic rises but conversion stays flat, check feed accuracy, stock, price and checkout before increasing spend. More budget will not fix a poor product match or a broken purchase journey.
If you want an independent review before peak, the Google Ads audit and strategy service covers tracking, feed, bidding and budgets in that order.
What each Black Friday check covers, when to run it and what happens if it is missed
| Item | When to Check | Key Tool or Setting | Main Risk if Skipped |
|---|---|---|---|
| Confirm tracking fires correctly and records purchase values | Before scaling spend; test and verify a purchase within a day | Google Ads conversion tracking, Tag Manager, GA4 | Duplicate or missing conversion data leads to unreliable reporting and bidding |
| Make sure the product feed matches the website | Before the sale and at least daily during it | Google Merchant Center feed and diagnostics | Product disapprovals, price mismatches, or ads for unavailable stock |
| Set budgets and pacing for the spike | Plan ahead; monitor hourly on peak sale days | Google Ads budgets and lost impression share reporting | Campaigns run out of budget during high-demand hours or overspend |
| Get bidding ready for promotional margins and volume | Ideally one or two weeks before the sale; avoid major changes on the day | Smart Bidding, target ROAS or CPA, custom labels | Unprofitable sales or reduced volume from unsuitable bidding targets |
| Refresh promotion assets and sale messaging | About a week before the sale; verify dates and approval | Merchant Center promotions, Google Ads promotion assets | Inaccurate or disapproved offers, or expired promotions remaining live |
| Refresh audience lists and set exclusions | Before the sale; check list size, status, and consent | Customer Match and Google Ads audience manager | Wasted spend, unusable lists, or data privacy non-compliance |
| Check landing pages and checkout speed | About a week before the sale; test pages and checkout on mobile and desktop | PageSpeed Insights, Lighthouse, real-device checkout tests | Slow pages, unclear offers, or checkout failures reduce conversions |
| Start early because demand builds in the 10 days before | Begin around three weeks before; have pre-sale campaigns live about ten days out | Dated campaign checklist, budgets, and promotion schedules | Rushed fixes, unsettled bidding, and missed pre-sale demand |
Start Now, Then Hold Steady Through Cyber Monday
Begin this week with tracking and the feed, because every other decision depends on them. If purchase values are wrong, your bidding targets are wrong. If the feed disagrees with the website, your best products may not show at all. Those two checks are unglamorous and they consume the first week, but they're the difference between managing the sale and guessing through it.
The scale of the opportunity justifies the effort, provided you measure it on profit. PwC UK's Black Friday research estimated consumers would spend £6.4 billion during Black Friday 2025, with average spending of £262 per person, based on a survey of 2,000 UK adults. It also found roughly four out of every five pounds would be spent online, including home delivery and click and collect. That mix is why feed prices, availability, delivery claims and local messaging need checking before spend scales, and why results should be read through conversion rate, average order value, cost of sale and margin by category, not clicks alone.
Set a dated checklist with a named owner for each item. Budgets, promotions, audience lists and landing page fixes should be in place before 17 November, when the ten-day demand build begins. After that point, resist large changes. New bid strategies, replacement feeds and untested promotion codes introduced in the final days carry approval and learning delays you can't afford, and they make it harder to tell whether a performance shift came from the market or from your own edits.
The accounts that trade well at peak aren't the ones making the cleverest change on the day. They're the ones with nothing left to fix.
On the morning of 27 November, check disapprovals, stock, budget pacing and conversion recording before you check ROAS. Do the same on 30 November, and reallocate budget early in the day when pacing or conversion rate moves, because a change made at 10am still has a trading day to work with. Afterwards, judge the event on net revenue after returns and margin by product, and annotate every change you made with its timing. That record becomes next year's starting point, and it's worth more than any single day's headline ROAS.
Start the countdown now and your Black Friday spend will be measurable, controlled and ready for the peak. If you want a second pair of eyes on the account before budgets rise, PPC Geeks can review the same checks in this checklist and tell you plainly what needs fixing first.
If your tracking, feed or budgets aren't ready for 27 November, PPC Geeks will audit your Google Ads account and give you a prioritised list of fixes to work through before peak. You'll get a clear view of where spend is being wasted and what to change first, with no obligation to take it further.
