How to structure Amazon UK PPC campaigns for profit in 2026

Split Amazon UK ads into discovery, performance and brand defence campaigns, set targets from your margins, and run one simple weekly routine.

The most reliable way to make Amazon UK advertising profitable is to stop asking one campaign to do everything. Give every campaign a single job: discovery campaigns find new search terms, performance campaigns spend on terms that already convert, and brand defence campaigns protect your own name and listings. Set targets from your product margins, judge the account on total advertising cost of sales as well as campaign ACoS, and follow the same routine every week.

Start with the numbers: break-even ACoS and TACoS

ACoS (advertising cost of sales) is ad spend divided by the sales Amazon attributes to your ads. Before you set a target, work out your break-even ACoS: the profit left on one unit after the referral fee, fulfilment costs, product cost, freight and VAT, expressed as a percentage of the selling price. For example, if a product sells for £20 and leaves £6 after every cost except advertising, its break-even ACoS is 30%. Above that, each ad-driven sale loses money; below it, you keep the difference.

TACoS (total advertising cost of sales) is ad spend divided by all sales of the product, organic and advertised. Most sellers calculate it themselves from Business Reports or their own sales data. TACoS shows whether advertising is building the business: if ad spend holds steady while organic sales grow, TACoS falls. A campaign can show an attractive ACoS while TACoS rises, which usually means ads are taking credit for sales you would have made anyway.

Use different targets for different jobs: discovery may run near break-even while it gathers data, performance should sit comfortably below it, and brand defence should be cheapest of all.

The three-tier campaign architecture

• Discovery (research): an automatic Sponsored Products campaign plus manual campaigns using broad and phrase match keywords and category targets. It surfaces search terms and competitor products that convert. Keep bids moderate and budgets capped so it never starves proven campaigns.
• Performance: exact match keywords and individual ASIN targets that have already produced orders in discovery. Most of your budget belongs here, with bids set against your target ACoS.
• Brand defence: keywords containing your brand name, and product targets aimed at your own listings so competitors have fewer chances to appear on your detail pages. Keep them separate so their low ACoS doesn't flatter the rest of the account.

Automatic campaigns have four targeting groups: close match, loose match, substitutes and complements. You can bid on each separately, pushing the groups that convert. Amazon does not let you change a campaign's targeting type after launch, and its own guidance is not to mix targeting strategies in the same campaign or ad group. Building each tier as separate campaigns respects both rules. Name campaigns consistently (tier, ad type, product, match type) so reports are quick to filter.

Match types and negative keywords

Broad match gives the widest reach and can include synonyms and related terms. Phrase match requires the words of your keyword in order, with plurals allowed. Exact match requires the same words in the same order, again including plurals, and usually converts best. Amazon's own advice is to bid highest on exact, lower on phrase and lowest on broad, because the wider the match, the less you know about intent.

Negatives keep the tiers apart. Sponsored Products supports negative exact and negative phrase keywords, plus negative product targeting to exclude specific ASINs. Terms move between tiers like this:

• Run the search term report for your discovery campaigns.
• When a search term has produced orders at or below your target ACoS, add it as an exact match keyword in a performance campaign.
• Add the same term as a negative exact in the discovery campaign it came from, so the two campaigns don't compete for the same click.
• Add terms that spend without converting, or are plainly irrelevant, as negative phrase or negative exact, depending on how broadly you want to block them.
• Treat ASINs the same way: move converting competitor ASINs into a product targeting campaign and exclude poor ones with negative product targeting.

Give a term enough clicks to judge before you cut it: a handful of clicks without an order tells you very little.

What each ad type is for

All Amazon ads need an active Professional selling account. Sponsored Products promotes individual listings in search results and on product pages, and your offer must be eligible for the Featured Offer (often called the Buy Box) to serve.

Sponsored Brands and Sponsored Display require enrolment in Amazon Brand Registry. Sponsored Brands shows your logo, a headline and several products or a video, and works well for brand defence and for broad category terms where you want to show a range. Sponsored Display reaches shoppers on and off Amazon and suits product targeting and remarketing; most sellers treat it as a supporting layer with a modest budget.

Attribution differs between them. For sellers, Amazon credits Sponsored Products sales within 7 days of a click, while Sponsored Brands and Sponsored Display use 14 days, so compare ad types with care. Formats and names also change often, so check what Campaign Manager currently offers in the UK before you plan.

Budgets, bidding strategies and placement adjustments

Budget follows the tiers: performance campaigns get first call, brand defence needs only enough to stay visible, and discovery gets a fixed allowance you raise when it is finding profitable terms. A campaign that runs out of budget early in the day is missing traffic.

Sponsored Products offers three bidding strategies. Dynamic bids (down only) lets Amazon lower your bid when a click looks less likely to convert. Dynamic bids (up and down) lets Amazon raise or lower bids by up to 100%, according to its help pages at the time of writing (November 2026). Fixed bids uses your exact bid. Down only is a sensible default for discovery; up and down suits proven exact match terms where extra visibility pays.

Placement adjustments raise bids for top of search (first page), rest of search and product pages, by up to 900%. They stack with dynamic bidding, so a modest base bid can become an expensive click. Check the placement report and change adjustments in small steps.

A weekly routine that keeps the account profitable

• Check account spend, ad sales, total sales and TACoS against last week and your plan.
• Judge a completed period. Amazon says sales data can take up to 12 hours to update, and attribution runs for 7 or 14 days, so the most recent days always look worse than they are.
• Harvest converting search terms into performance campaigns and add the matching negatives in discovery.
• Add negatives for terms and ASINs that have spent meaningfully without converting.
• Adjust bids where there is enough data: lower them on targets above target ACoS, raise them on targets well below it.
• Review the placement report and budget status for every performance campaign.
• Check stock and the Featured Offer on advertised products, because ads stop serving without them.

Once a month, compare TACoS by product, retire targets that no longer pay, and plan seasonal budgets before events, not during them.
