E-Commerce Google Ads Management | ROAS-Focused
Google Ads management for e-commerce works differently from service businesses. Conversion value matters more than conversion count, the product feed is nearly half the campaign, and which product you push with the same budget changes profit directly.
Feed quality is half the campaign
Google Shopping and Performance Max campaigns are fed by the product feed. If title, category, brand, GTIN and image fields are incomplete, the product appears in fewer searches — no matter how good the campaign settings are.
One of the highest-return changes is bringing product titles closer to how people actually search. Whatever word the customer uses to look for the product should appear in the title, not your internal catalogue code. Clearing approval errors in Merchant Center matters just as much: a disapproved product never serves, and it happens silently.
Value, not conversion count
In e-commerce not every sale carries the same value. A bidding strategy targeting conversion count can sell many cheap items and neglect expensive ones; revenue looks fine while profit falls.
That is why I use value-based bidding and bring the reported conversion value closer to real value. Ideally the value sent accounts for margin too: of two products producing the same revenue, the higher-margin one should look more valuable to the algorithm. This depends on conversion measurement being configured correctly.
The reality of returns and stock
Two frequently skipped items in measurement are return rate and stock status. Evaluating a high-return category on revenue alone makes it look profitable while it actually loses money. Advertising products that are out of stock is direct waste; when feed and stock fall out of sync, this can go unnoticed for months.
Cart abandonment and existing customers
People who add to cart without buying are e-commerce’s most valuable remarketing audience. In a remarketing campaign this group is kept separate and targeted with its own message.
Existing customers should be separated too: in a campaign aimed at acquiring new customers, spending on people who already bought is a common source of loss. Google Ads supports this distinction, but it is not configured by default.
The platform side
Shopify, WooCommerce or a custom stack — whichever it is, the measurement layer has to be built correctly. If the site is slow, ad performance drops with it; where needed, WordPress speed optimisation is handled as separate work.
How do we start? First I audit your feed and measurement setup — disapproved products, missing fields, incorrect conversion values. I send the findings in priority order in writing. You can reach me from the contact page.
Frequently Asked Questions
How should I set my target ROAS?
It is calculated backwards from your margin: the lower your margin, the higher the target ROAS has to be. Industry averages floating around are meaningless without knowing your own cost structure.
Should all products sit in one campaign?
No. Product groups with different margins, price ranges and conversion behaviour should be handled separately; otherwise budget drifts to the most-clicked but least-profitable group.
Does it make sense for a small shop?
It can, even with a small catalogue, but the budget has to generate enough data to teach the algorithm. With a very narrow catalogue, starting on Search to accumulate data is the healthier path.
