00 The diagnosis library
Wasted ad spend, diagnosed.
Every founder I audit suspects their ads are leaking money. Most are right. This library covers the signals, the metrics that flag each one, and the tools to confirm them on your own account. Read the umbrella answer below, then jump to the specific question you came to answer.

01 The direct answer
How do I tell if
my ads are leaking?
Five signals indicate wasted ad spend. Search-term reports with more than twenty-five percent irrelevant queries. Branded-search overlap inflating reported ROAS. Display Network spend with no conversion attribution. Conversion rates falling outside the platform-vertical benchmark band. Cost-per-acquisition climbing while contribution margin holds flat. Any one of these on its own is normal noise. Two together is the moment to pull a real audit.
None of these signals require special tooling. Every one of them shows up in Google Ads, GA4, and Shopify reporting that you already have. The reason most founders miss them is that the ad platforms surface optimization scores and recommendations that point in the wrong direction. The platform is incentivized to tell you to spend more. A senior operator is incentivized to tell you what to cut.
The questions below walk through each signal in detail. I treat them as one diagnostic pass, not fifty separate problems. A leak in one place almost always means a leak in three others.
02 The five signals
Five signals.
One pattern.
-
SIGNAL 01
Irrelevant search queries
Open the search-term report. If more than a quarter of the queries that triggered your ads describe a different product, a different intent, or a job-seeker looking for employment, you are paying Google to teach broad match what your business is not. The fix is structural, not a list of negatives. Match types, audience signals, and bidding strategy all conspire here.
-
SIGNAL 02
Branded search dressed up as performance
Branded search queries convert at four to six times the rate of non-branded search. If your reported ROAS lives in the 5x to 8x band and most of your spend is on campaigns that include brand traffic, the math is misleading. You are paying Google for traffic that would have arrived organically. Strip branded campaigns out and read the number again.
-
SIGNAL 03
Display and partner-network spend
Performance Max and Display campaigns rarely report the network breakdown clearly. Pull the placement report. If a non-trivial share of spend is going to mobile-app placements, parked-domain networks, or the Display Network at large, that money is doing almost no work for a Shopify store. Exclude the worst placements explicitly. Trust nothing the platform auto-suggests here.
-
SIGNAL 04
Conversion rates outside the benchmark band
Median ecommerce conversion rates sit between one-and-a-half and three percent across most home and furniture verticals. A campaign-level rate below half a percent on relevant traffic is almost always a landing-page problem, a tracking problem, or a match-type problem. A rate above eight percent on a high-volume campaign almost always means branded overlap or de-duplication failure.
-
SIGNAL 05
CPA rising while contribution margin holds flat
Cost-per-acquisition climbs over time in most paid accounts. That is not waste on its own. It becomes waste when CPA climbs faster than average order value, contribution margin holds flat, and the founder is told to "trust the algorithm" through the worsening trend. The fix is not more spend. It is a budget redistribution between campaigns and a fresh read on which audiences are actually compounding.

05 What I do with this
Same diagnosis,
run by a senior operator.
Every founder reading this can run the diagnosis on their own account. The library is built so they can. Some founders read it and the next move is obvious. Some founders read it and decide the next move is to hand the account to someone who has done this hundreds of times.
That is what I do. I am Conner Crowe. I spent ten years inside agencies and in-house teams, and the last two managing $15M of ad spend for founders direct. Same person on the call as on the keyboard. No account manager. Written Monday summary. One senior operator. Paid like a fractional CMO. Diagnostic depth of a forensic auditor.
If the library got you to the answer, that is the point. If the library convinced you the diagnosis is bigger than what one founder can run on a weekend, that is also the point. The book-a-call link is below.
Want this diagnosed in your account?
Same diagnosis,
run on your account.
Thirty minutes on the phone. I look at your spend, your tracking, and your search-term reports before the call. You walk out with a clear list of what is leaking and what to fix first.
