Ecommerce Google Ads: Shopping, Performance Max and feeds

Ecommerce Google Ads is a feed and structure problem before it is a bidding problem. Products grouped badly, feeds that don't match how people search, and attribution that credits the wrong channel will cap any account, however good the bid strategy.

Two accounts show what fixing the foundation does. A North American ecommerce brand grew revenue from $257K to $610K year on year on $60K a month (case study). A Nordic home and hardware retailer drove 36,600 conversions in a month at $1.78 each (case study).

Account structure and bidding tiers

We consolidate fragmented campaigns, separate brand from non-brand, and group products into bidding tiers by margin and performance. The ecommerce brand above went from a fragmented account with no bidding hierarchy to properly trained Target ROAS strategies, and ROAS improved 12.4% even as spend rose 111%.

A practical structure: one branded campaign, a Shopping or Performance Max campaign per margin tier, and a separate campaign for bestsellers with their own budget so they never run out. Use custom labels for margin, price band, seasonality and stock status so you can move budget without rebuilding campaigns.

Product feeds

Titles, attributes and custom labels decide which searches your products can show for. Rewriting feed titles to match real search language and labelling products by margin and stock is often the fastest win in an ecommerce account.

Start with the 20% of products that drive 80% of revenue. Put the search term buyers actually use at the front of the title, add brand, key attribute (size, material, colour) and product type, and fill every optional attribute Google accepts. Check the diagnostics tab weekly for disapprovals and price mismatches.

Performance Max and Shopping

Performance Max needs asset groups aligned to product categories, audience signals from customer lists, and brand exclusions so it doesn't take credit for branded searches. Inventory-level bidding helped the Nordic retailer promote in-stock items and suppress out-of-stock SKUs automatically.

Keep one Standard Shopping campaign running alongside Performance Max for your top products if you need query-level control, and compare incrementality before moving all spend into PMax.

Seasonality and local

Seasonal campaign structures built for peak periods drove 40% higher conversion rates for the Nordic retailer. Store-visit attribution showed that 22% of in-store purchasers had seen a digital ad in the previous 30 days, which changed how the budget was judged.

Build seasonal campaigns ahead of peak with their own budgets and bid adjustments, and plan the ramp-down so you are not paying peak prices after demand drops. For retailers with stores, turn on store-visit or local conversion tracking so offline sales count in the numbers.

Attribution for ecommerce

Correcting attribution showed that 28% of the ecommerce brand's revenue came from under-credited channels. Our attribution work rebuilds conversion tracking so budget follows real contribution.

Reconcile Google-reported revenue against your store platform every month. If the gap keeps widening, fix tracking first: deduplicate purchases, pass the real order value including discounts, and make sure returns and cancellations are not counted as revenue.

Conversion rate

Every point of conversion rate lowers the cost of every channel feeding the site. See our CRO and landing page approach.

Product page speed, clear delivery costs, visible returns policy and a short checkout usually matter more than design changes. Test them in that order.

Frequently asked questions

Is Performance Max good for ecommerce?

Yes, when asset groups follow your product categories, feeds are optimised, and brand terms are excluded so it cannot claim credit for branded demand.

What is the fastest way to improve Shopping performance?

Product feed titles and custom labels. Matching titles to how people search and labelling products by margin lets you bid where profit is highest.

How much does ecommerce Google Ads management cost?

Agency fees are typically a percentage of spend or a fixed retainer. What matters more is whether the account is measured on revenue and margin rather than platform ROAS.
