What garbage spend is, and why you can't see it in the dashboard
Garbage spend is Google Ads budget that buys clicks with no realistic chance of converting, and the search terms report is the fastest place to find it.
By Nathanaël Morin, Partner, Director of Technology[CONTENT NEEDED — date]12 min read
Every dollar of garbage spend buys a real click from a real person. The problem is who that person is: someone researching a DIY fix, someone in a city you don't serve, someone searching for your own brand name who would have found you for free. Google charges you the same either way. Your budget shrinks, your pipeline doesn't grow, and nothing in the account looks broken.
It stays invisible because the platform's default settings are tuned to spend your budget, not to scrutinize it:
- Broad match defaults let your keywords trigger on loosely related searches, so your ad shows for queries you never chose.
- "Presence or interest" location targeting serves your ads to people merely interested in your area, not actually in it.
- Auto-applied recommendations quietly change keywords, match types and bids unless you switch them off.
- Blended Performance Max reporting rolls cheap brand clicks and expensive cold clicks into one tidy average.
Your dashboard reports averages. Garbage spend lives in the line items underneath the averages.
Why a healthy dashboard can hide a leaking account
A top-line view can show a reasonable cost per click and a steady stream of conversions while a third of the search terms underneath are junk. One strong keyword props up the average. PMax blends brand and non-brand into a single number. A "conversion" might be a page scroll, not a qualified lead. In the accounts we take over, the surface metrics and the line items often tell two different stories.
This is why gut feel fails as an audit method. You can't sense a bad location setting or a quiet auto-applied recommendation. You can only find them by checking specific places in a specific order. The seven red flags below give you those exact places, starting inside the account itself.
In-Account Red Flags
Open these screens and you'll see what your budget really buys
Garbage spend is budget that buys clicks with no realistic chance of converting, and the search terms report is the fastest place to find it. Each check below takes about one minute inside your own account.
-
A search terms report nobody has opened
Read the actual queries your money bought, not the keywords you chose. Months of irrelevant searches and an empty negative keyword list mean every off-target click was paid for in full.

-
Conversions that count junk, not customers
If page views, every form fire or duplicate events count as conversions, Google bids toward noise instead of revenue. Real leads and sales tracked through GA4, GTM and Enhanced Conversions is the standard to hold it to.

-
Auto-applied recommendations rewriting your account
With auto-apply switched on, Google adds keywords and changes settings with no human sign-off. The account quietly drifts toward more spend, and nobody can say who approved what.

Beyond the Settings
Some red flags live in your agency, not your account
Settings can be fixed in an afternoon. Incentives cannot. Three behaviours tell you whether the people running your account profit from the waste you just found, and each one has a full guide of its own when you want to dig deeper.
Our Google Ads landing pages have performed much better since we started working with them.
The three behavioural red flags
- You don't hold admin access to your own Google Ads account. The Account Ownership and Contract Terms guide covers exactly what to demand back.
- The agency is paid a percent of your spend, so a bigger budget pays it better than a cheaper lead does. The Pricing Models guide breaks down how that math works against you.
- Reports talk impressions and clicks, never cost per qualified lead or ROAS. If you can't see what a sale costs, neither can your agency.
- The contrast worth knowing: a flat retainer with no contract ties the agency's pay to keeping your results, not to growing your budget.
The 20-Minute Self-Audit
Run it before you call anyone
You can do this yourself, in your own account, in about 20 minutes. No tool, no expert, no permission needed. The output is one number: the spend behind everything you flag.
-
Pull 30 days of search terms
In Google Ads, open the search terms report and set the date range to the last 30 days. Highlight every query that has no realistic chance of becoming a customer: wrong product, wrong place, wrong intent.
→ a highlighted list of clicks you paid for but never wanted -
Check match types and negatives
Open your keywords and note where broad match is running. Then open the negative keyword lists. If broad match runs against a thin or empty negative list, your highlights from step one now have an explanation.
→ you know whether the leak is structural or a one-off -
Audit the settings Google chose for you
Open your conversion settings and verify what actually counts as a conversion: a qualified lead or sale, not a page view. Then check each campaign's location setting for "presence or interest", and review the auto-applied recommendations history for changes you never approved.
→ every default working against your budget is on the table -
Total the spend behind your flags
Add up the cost of every query, keyword, setting, and auto-applied change you flagged. That figure is your garbage spend: budget that bought clicks with no realistic chance of converting. You now have evidence, not a suspicion.
→ a real dollar number, not a hunch

Before You Open Your Account
Garbage spend questions owners actually ask
How much of my budget is likely wasted?
There is no honest universal number. The waste depends on your match types, your negatives, your conversion setup and how long the account has run on defaults. That is why the self-audit ends with a total: add up the spend behind everything you flagged, and that is your number, not an industry average. [STAT — CONTENT NEEDED: IMG Media's internal observation on the typical share of audited budget found wasted.]
How often should I audit my Google Ads account?
At minimum quarterly. Run it again any time something changes: a new agency takes over, the budget moves up or down, or a new campaign type launches. Settings drift back toward Google's defaults faster than most owners expect.
Is Performance Max itself a red flag?
No. Unmanaged Performance Max is. Without brand exclusions, PMax happily buys searches for your own name that would have converted anyway. Without clean conversion data, it optimizes toward whatever it can count, including junk events. Managed with both in place, it is a legitimate part of the channel set.
Can I fix these issues myself?
Some of them, yes. The self-audit finds the problems, and quick wins like turning off auto-applied recommendations or adding obvious negative keywords are within anyone's reach. Fixing bid strategy, rebuilding conversion tracking and restructuring campaigns is harder, and it is exactly where a specialist earns the retainer.
What does a professional audit check that this list doesn't?
Three layers the 20-minute version can't reach: whether your bid strategy fits your economics (a target ROAS set wrong wastes money invisibly), whether the conversion data flowing through GA4 and GTM is actually trustworthy, and whether the campaign structure across Search, Performance Max and Demand Gen makes the budget work as one system instead of competing with itself.
Isn't an audit just a trick to poach my account?
Often it is, which is why the full checklist sits on this page with nothing gated. You can run it without talking to anyone. And because IMG Media works without a long-term contract, even hiring the agency to fix what you found doesn't lock you in. If you are weighing a switch, start with the full agency selection checklist.
