Most European sellers raise PPC budgets for Q4 before they clean up what those budgets are already funding. That order is backwards. Every euro of wasted spend in your current campaigns doesn't disappear when the budget goes up — it just gets bigger. The ten days before Black Friday week are the cheapest time of the year to fix a PPC account, because traffic hasn't surged yet and mistakes are still small. Here's the audit to run this week, before you touch a single bid.
1. Pull 60 days of Search Term Reports and flag the dead weight.
Export Search Term Reports for every active Sponsored Products and Sponsored Brands campaign across your markets, going back 60 days. Sort by spend descending, then flag any search term with at least 15 clicks and zero orders. On most accounts we audit, 8–15% of total ad spend sits on fewer than 30 search terms that have never converted. These aren't close misses — they're terms that look relevant to the algorithm but don't match actual buyer intent on your listing. Convert every flagged term to a negative exact match at the ad group level before Friday.
2. Check for negation conflicts, not just missing negatives.
The more damaging problem isn't missing negatives — it's negatives that fight each other. A broad match campaign pushing a converting term, while an adjacent campaign has silently negated that same term as "irrelevant" three months ago, is common on accounts running more than 15 campaigns per market. Pull your full negative keyword list per campaign and cross-reference it against your current top-20 converting search terms. Any overlap is actively suppressing your own best traffic. This single check alone recovers measurable impressions in multi-campaign accounts without raising a single bid.
3. Reallocate budget from stagnant campaigns before raising total spend.
Before adding fresh Q4 budget, look at campaigns that have been capped (budget-limited) for more than 5 of the last 14 days with ACoS below your target. These are starved winners — proven converters that are losing sales purely because the budget runs out mid-day. Shift budget from campaigns with flat or declining CTR over the same period into these capped winners first. Only once your existing budget is correctly distributed does it make sense to add net new spend for the surge.
4. Treat each European market as a separate audit, not a translated one.
A search term that's dead weight on amazon.de can be a top converter on amazon.fr, and vice versa — buyer vocabulary and comparison behaviour differ by market, as we've covered before. Run this audit market by market, not once across a merged export. A negative keyword applied at the portfolio level because it underperformed in one market can quietly suppress a converting term in another. If you manage FR, DE, IT, ES and UK campaigns, budget roughly 45–60 minutes per market for this pass — it's the highest-leverage hour you'll spend before the surge.
5. Lock your changes 48 hours before the demand curve starts moving.
Amazon's algorithm needs a few days to re-stabilise bid delivery after a batch of negative keyword and budget changes. Make this pass by Wednesday or Thursday this week, not the weekend before Black Friday — changes made too close to the surge introduce noise exactly when you need your data to be clean. Once the audit is locked, the next move is restructuring bids and dayparting for the surge itself, which is a separate pass once your account isn't bleeding on terms that were never going to convert.
A clean account absorbs a Q4 budget increase efficiently. A dirty one just burns the increase faster. Run the audit first.
