Magnifying glass over an ad account dashboard

We audit Shopify Google Ads accounts every week. Different niches, different budgets, different countries. Yet in 80% of them we find the same four problems, and together they decide whether ads pay off.

None of them is exotic. Each one quietly burns part of the budget every day, and most store owners never see it in the Google Ads interface. Here is what they look like and how to check your own account.

Key takeaways

Split campaigns by margin and product role, not by one Performance Max for everything.
Switch off what never paid back, every week.
The ad, the product page and the feed must say the same thing.
Fix tracking before you touch the budget.

1. Wrong account structure

Bestsellers, new products and low-margin items share one campaign. Google spends where it is easiest to get a conversion, not where you earn. Usually that means your best-known product, which would often sell without ads anyway.

What we do instead: separate asset groups by margin and product role. Brand searches and bestsellers live apart from new products, so the algorithm learns from profitable sales and new products get their own budget to prove themselves.

2. Budget leaks

Money goes to campaigns and search terms that never pay back, and nobody switches them off. A typical leak: broad searches with “free”, “DIY” or a competitor’s name that bring clicks and no sales for months.

Open the search terms report for the last 90 days.
Sort by cost, filter conversions = 0.
Everything above one average order value is a candidate for a negative keyword.

3. A weak product-site-ad link

The ad promises one thing, the product page shows another, and the visitor leaves. A discount in the ad that is not visible on the page. A product title in the feed that does not match the page. A landing page that opens on the collection instead of the product.

This is where Google Ads and conversion work meet. Better ads do not help if the page loses the shopper in the first three seconds.

4. Broken tracking

Purchases are counted twice or not at all, so Google optimises for the wrong signal. The most common cause is duplicate tags: one from an old app, one from the Google channel, one added by hand. The result is a ROAS that looks great in Google Ads and does not match Shopify.

We set up GA4, Google Ads conversions and enhanced conversions on Shopify Customer Events. Our setups pass 90% of purchases correctly to analytics, so both numbers finally match.

A 10-minute self-check

Compare last month’s purchases in Google Ads with orders in Shopify. A gap above 15% means tracking needs work.
Count your campaigns. One Performance Max for the whole catalogue is a red flag.
Open the search terms report and look for expensive terms with zero sales.
Click your own top ad and check that the price, offer and product match the page.

If two or more answers worry you, the account is leaking money every day. The good news: these fixes usually show results in 2–4 weeks.
