You can buy more of it any time by bidding harder on searches you would have won anyway. The harder question is whether each campaign is funding products that actually make money once margin, returns and discounting are taken out. Three patterns show up in almost every ecommerce account we take over. ### Performance Max eating your brand The lever → Pooled PMax budgets quietly absorb brand and high-intent searches, then take the credit. ROAS looks strong, but a lot of it is demand you already had. The fix → Brand exclusions on Performance Max, asset and search-theme review, and budget caps, so PMax is measured on the new business it actually brings in rather than the brand searches it intercepts. ### A Shopping feed working against you The lever → Thin titles, missing attributes and a single pooled Shopping campaign mean Google spends evenly across the catalogue, including products with poor margin, low stock or weak conversion rates. The fix → Feed quality work and a listing-group structure that splits campaigns by product economics, so budget weights towards the products that sell and make money, not just the ones that get clicks. ### One blended ROAS hiding everything The lever → When Search, Shopping and PMax report into a single ROAS figure, you cannot see which channel is carrying the account and which is leaking. Scaling the blend scales the waste with it. The fix → Separate the channels, attach real revenue values (and margin where the data supports it), so each campaign type can be judged on its own and budget can move with confidence. ## Where ecommerce budget leaks When the reports look fine but profit is not growing, the budget is usually going to one of these four problems. Every engagement starts with a senior audit that shows exactly where the money went. ### Spend spread evenly across the catalogue A single Shopping campaign treats your best-margin hero product and your worst clearance line the same. The fix → Margin-aware campaign splits and listing-group structure, so budget concentrates where it earns. ### Feed errors capping reach Disapprovals, missing GTINs and weak titles mean products silently drop out of auctions you should be winning. The fix → A feed audit and ongoing feed checks, so the catalogue stays eligible and competitive. ### Performance Max with no visibility Pooled budgets make it hard to see where PMax is taking brand search or spending on products that do not sell. The fix → Brand exclusions, search-theme review and budget caps, so PMax earns its place. ### Seasonality handled by guesswork Peak demand is over-throttled and quiet periods are over-funded because there is no forecast behind the budget. The fix → Seasonal budget planning and forecasting, so spend leads demand instead of chasing it.

Worth a conversation if - Shopping and PMax spend is commercially material and someone is asking what it actually returned after margin - Revenue is growing but profit is not, and you cannot see which channel is responsible - Search, Shopping and Performance Max budgets are pooled, so you cannot tell what each is returning - You need a feed and budget plan ready for the next peak Probably not a fit if - You are launching a first store with a catalogue and budget too small to fund real testing - Price is the only criterion on the agency shortlist - You cannot share feed or revenue data, so there is no reliable way to optimise - You want guaranteed ROAS or overnight results; we do not sell either ## Related PPC services [Google Shopping & feed management Fix the feed that decides which searches your products win.](https://cleandigital.co.uk/google-shopping-management) [Performance Max management Control PMax so it adds incremental revenue rather than brand you already had.](https://cleandigital.co.uk/performance-max-management) [Conversion tracking & measurement Real revenue values so bidding optimises for profit.](https://cleandigital.co.uk/conversion-tracking) [Google Ads management The full Google-side service this sits within.](https://cleandigital.co.uk/google-ads-agency) [Lead generation PPC The same senior team, for accounts where a lead is not a sale.](https://cleandigital.co.uk/lead-generation-ppc) [Paid search management The wider PPC programme across Google and Microsoft.](https://cleandigital.co.uk/paid-search) ## FAQs Common questions ecommerce teams ask before handing a Shopping and Performance Max account to an agency. ```json {"@context":"https://schema.org","@type":"ProfessionalService","name":"Clean Digital - Ecommerce PPC agency","url":"https://cleandigital.co.uk/ecommerce-ppc","logo":"https://cleandigital.co.uk/logo.png","description":"UK ecommerce PPC agency and Google Premier Partner.
