7 signs your Google Ads account is wasting budget

By Ahmed Imran · Updated June 2026 · 6 min read

Most wasted Google Ads budget hides in the same seven places, and you can check every one of them yourself in about 20 minutes. This is the checklist I run at the start of every audit, with what bad looks like in each report.

Every client number in this article comes from accounts I have audited or rebuilt myself. You do not need an expert to find most budget waste. You need about 20 minutes and access to your own account. Here are the seven checks I run first on every audit.

Is your search terms report full of junk queries?

Broad match keywords backed by a thin negative list is the leak I find most often. Google has turned broad match on by default for new Search campaigns using Smart Bidding since July 2024, so plenty of advertisers run it without ever choosing it. Broad match can work, but only with deep negative lists and accurate conversion data steering the bidding.

When Atlas Labs, a SaaS company, came to me, the entire account ran on broad match and a conversion cost $108. I rebuilt it on phrase and exact match, and the cost per conversion was $61.54 within one month.

• ›Open Insights and reports, then Search terms, and sort the last 30 days by cost
• ›Count how many of your top 50 queries you would never knowingly pay for
• ›Check your negative keyword lists. Months of spend with only a handful of negatives is the tell

Can you separate brand spend from non brand spend?

Brand clicks come from people who already searched your name, so they are cheap and they convert. Blend them with non brand campaigns and the combined ROAS looks healthy while prospecting quietly loses money. If your reporting shows one blended number, you cannot see what a new customer actually costs.

• ›Filter the search terms report by your brand name and note how much spend it absorbs
• ›Check whether brand terms sit in their own campaign with a separate budget
• ›Ask for non brand cost per acquisition by itself. If nobody can produce it, you found the sign

Is your conversion tracking counting things that matter?

Smart Bidding optimizes toward whatever you count as a conversion. I audit accounts where page views are marked primary and where a spam form fill carries the same weight as a qualified lead. The algorithm then dutifully buys more of the cheap junk. For lead gen, offline conversion tracking that feeds CRM outcomes back into Google Ads is the difference between optimizing to leads and optimizing to revenue.

• ›Open Goals, then Conversions, then Summary, and read what is marked primary
• ›Flag anything that is a click or a page view rather than a business outcome
• ›If you run lead gen, ask whether qualified leads are imported back from your CRM

Is Performance Max running without guardrails?

Performance Max will spend your budget somewhere, and without guardrails you cannot see where. The two gaps I find most often are missing brand exclusions, which let the campaign take credit for searches you would have won anyway, and one catch all asset group with no listing group structure behind it.

At Autobuffy, an auto parts ecommerce client, I used Google Ads scripts to surface what I call zombie products: items getting zero impressions while the budget pooled on a few bestsellers. Fixing that distribution was central to scaling the account to $1.5 million in revenue in eight months at 6.89x ROAS.

• ›Open the Products report and filter for items with zero impressions in the last 30 days
• ›Confirm a brand exclusion list is applied to every Performance Max campaign

When was your account last touched?

Change history does not lie. Search for it in your account, set the range to the last 90 days, and filter out the automated entries. If all that remains is a budget tweak or two, nobody is managing the account. Plenty of agencies set and forget, then send a monthly report that describes the drift instead of correcting it.

White Hat Insurance came to me with cost per lead at $300 under the prior manager. Restructuring cut it to $134 within three weeks, and the latest week came in at $75. The account did not need more budget. It needed someone working in it.

Does your manager earn more when you spend more?

Percent of spend pricing builds a quiet conflict of interest into the relationship. When the fee is a percentage of what you spend, every wasted dollar the manager cuts also cuts their own pay. I am not claiming every manager acts on that incentive, but incentives shape attention over time. You can check this one in two minutes by rereading your contract.

It is why I charge a flat monthly fee, starting at $1,100 and tiered by ad spend rather than taken from it. Cutting your waste never reduces my income, so I cut it.

Is a single experiment running right now?

Open Campaigns, then Experiments. In most accounts I audit, that page has never been used. No bidding strategy has ever been tested against another and no landing page has ever been split. An account that never tests can only drift.

Laminaat Paleis, a flooring retailer in the Netherlands, shows what disciplined iteration looks like instead. I cut about 65 percent of wasted reach year over year while holding spend flat, and the account delivered 5,233 leads at €10.92 each. That came from months of small controlled changes, not one dramatic rebuild.

What to do if you found one of these signs

Resist the urge to tear everything down overnight. A full rebuild resets bidding data you may want to keep. Fix conversion tracking first, because every other decision depends on what the account counts. Once the data is trustworthy, cut the obvious waste, and only then think about restructure.

If you would rather have an experienced second pair of eyes, I run a free Google Ads audit that checks these exact seven signs in your account, along with the tracking and structure issues underneath them. You get written findings whether or not we ever work together, and because I never charge a percent of spend, finding your waste is the entire point.
