Google Ads audit for e-commerce brands, checked against your margin

A Google Ads audit checks your ad account across 13 areas, from break-even ROAS and conversion tracking to brand share, search terms, Shopping, remarketing and scripts. For each area you see what we check and why it costs you money. We reconcile the account with your shop backend, so you know which revenue your ads really create. What to do about each finding, we cover on the intro call.

The Google Ads audit checklist: 13 areas

Most free audit tools score ad copy and keywords. The expensive problems usually sit in tracking, brand share and budget split, and a tool can't see your margin. Our PPC audit service works through these 13 areas:

1. Unit economics and break-even

We work out your break-even ROAS from product cost, shipping, payment fees and returns. Without that line, a ROAS of 3 could mean profit or loss.

2. Conversion tracking

Which conversion actions count as primary, what gets counted twice, and whether reported revenue matches your shop. Smart Bidding optimizes toward whatever sits here.

3. Brand share

How much of your reported revenue comes from searches for your own brand name. Many of those buyers would have found you without an ad.

4. Account structure

Campaign types, budget shares and ROAS per campaign. We see whether the budget sits with the campaigns that earn contribution margin.

5. Search terms

Which queries actually cost you clicks, and how much budget goes to searches with no buying intent. With Google Ads AI Max, Google picks even more queries on its own.

6. Keywords and Quality Score

Match types, duplicates and Quality Score. A low Quality Score makes every click more expensive.

7. Locations

Spend and revenue by region. Some regions never buy, and the budget keeps flowing there.

8. Devices

Conversion rate and ROAS on mobile, desktop and tablet. Big gaps without bid adjustments leave revenue on the table.

9. Hours and weekdays

Performance by hour and day. Late-night clicks often run without orders.

10. Shopping and Merchant Center

Feed quality, disapproved products and revenue per product. We see how many products take budget without ever selling at a profit.

11. Remarketing

Which audiences exist and whether any campaign uses them. Visitors who already reached the cart are your cheapest buyers.

12. Ads and assets

Ad copy, ad strength and assets. We check whether your ads list product specs or give a reason to buy.

13. Scripts and rules

Automated rules, alerts and scripts. Without them, nobody notices when a budget runs dry overnight or a feed breaks.

The audit shows where money leaks and how much. The plan for fixing it comes on the intro call.

What we find most often in 41 audits

The Harucon analysis of 41 audits covers e-commerce Google Ads accounts in the US, UK and DACH, with annual budgets from five to seven figures (audits from recent years through 2026). The counts are lower bounds: we only count what an audit documented.

Brand share: the biggest blind spot

In 8 audits with measured values, 58 to 94% of reported revenue came through searches for the brand's own name, with the middle at 82 to 85%. An account like that can show a healthy ROAS and still win very few new buyers.

Products that never pay off

In 3 audits with measured values, 90 to 98% of products never made a profitable sale through Google Ads. One account put 87% of its budget into products without a single profitable conversion.

Tracking that counts the wrong thing

According to Google Ads Help, only primary conversion actions feed into bidding. In the audits we found add to cart set as the primary goal instead of purchase (in 2 accounts), and more than 130 conversion actions with at least 6 parallel purchase actions. Smart Bidding then optimizes toward numbers your shop never sees. The basics of Google Ads conversion tracking are in our guide. How we measure in the shop backend as a Google Ads agency is on our services page.

One account ran for twelve months at a ROAS of 1.16 against a real break-even of 1.85. Not a single month reached it. The ad account showed revenue. The shop showed a loss.

Check your account first: the free audit script

Want to know where your account stands before we talk? Our script checks 10 signals from these audits inside your account and returns a traffic-light scorecard without changing anything.

Free Google Ads script

Script: Google Ads account check

Checks 10 signals from real audits (structure, brand, devices, geo, hours, keywords, conversions) and returns a traffic-light scorecard.

Read-only, the script changes nothing in your account. Privacy

The script flags warning signs in the ad account. It can't see break-even, brand share of shop revenue or products that never make a profit, because those need shop data and margins. The full audit covers them.

Who a Google Ads audit is for

  • You sell through your own online store and Google Ads is one of your largest channels.
  • The ad account reports a good ROAS, but less arrives in your shop.
  • Performance Max takes budget and nobody can tell you what for.
  • You're thinking about switching agencies and want a second opinion first.
  • Nobody from outside has looked at your account in over a year.

The guarantee starts at $3M in annual revenue. You can still book a call below that, and we show you which starting point fits your brand.

How to tell a useful PPC audit from a generic one

Some audits are auto-generated checklists with a score at the top. A useful one answers five questions:

  1. Does it know your break-even ROAS? Without your margin and returns, nobody can judge a ROAS.
  2. Does it reconcile with your shop backend? Numbers from the ad account only show what Google reports.
  3. Does it put a number on brand share? Only then do you see what ads add in new buyers.
  4. Does it attach dollar amounts? Each finding needs a figure, or you can't rank them.
  5. Who did it? A tool, or someone who runs accounts of your size?

The guarantee terms are on our homepage.
