Advertisers can identify wasted spend inside Google Ads accounts by reviewing search terms reports, conversion tracking and budget settings. These three checks help advertisers find where they’re spending money without getting results.
Many businesses rarely check these reports, so they continue wasting money on ads month after month. At SlamStop, we see the same pattern in accounts of every size, including single-van trades and national online stores.
In this guide, we’ll show you where your ad budget goes and how to reduce wasted spending. You’ll also learn how to adjust your Google Ads settings to get better results.
Why So Many Businesses Waste Money on Google Ads and Paid Search
Most businesses waste part of their Google Ads budget on clicks that never lead to sales. They keep paying for traffic, but enquiries remain low. Those visitors often have little interest in their products or services. You’ve probably noticed your monthly Google Ads bill growing without seeing enough leads to justify the cost.
The problem often starts with how you set up your Google Ads campaign. If you leave the default settings unchanged, your ads may appear on the Display Network as well as Google Search. That’s how you could end up paying for clicks from people who aren’t looking for your products or services.
For instance, a plumber in Geelong might pay for clicks from people reading about fixing their own taps (and they were never going to ring).
Without regular checks, those wasted clicks can keep draining your ad budget for months. Some keywords bring in customers, while others only use up the budget. We’ve audited accounts across trades, retail and services and often found the same settings unchanged six months later.
And because Google Ads charges for every click, leaving those settings unchecked can cost you money every day. SEO, social media and content marketing work differently, as a slow week may only cost you time.
Where Does Google Ads Wasted Spend Hide in a Google Ads Account?
Google Ads can also waste your budget through broad match keywords, irrelevant search terms, and landing pages that fail to convert. Each issue wastes money differently, so you need to check all three to find where your budget goes.
Work through them in this order, since the first problem usually explains the other two.
Broad Match Keywords Pulling in the Wrong Searches
Broad match lets Google show your ads for searches it considers related to your keyword. These related searches may not share any words with your chosen keyword.
For example, a broad match keyword like “office cleaning” may attract searches for cleaning jobs, courses, and free checklists. However, those searchers aren’t looking to hire a cleaning service (so their clicks can waste your ad budget).
Phrase and exact match give you more control over which searches show your ads. Most Google Ads campaigns do better starting with a narrow match type and widening only where the numbers earn it.
Search Terms Reports Full of Junk Queries
Your search terms report shows the actual queries people typed before clicking. That makes it the closest thing to an itemised receipt your account gives you.
Review your search terms report weekly and sort the results by cost to find searches with zero conversions. You’ll often find job seekers, students and bargain hunters wasting your daily budget.
Once you identify these irrelevant searches, add them to your negative keyword list. Google’s own Ads Help Centre recommends reviewing search terms, which can help you avoid paying for irrelevant clicks.
Are Your Landing Pages Losing the Click?
Yes, your landing pages can lose potential customers when they offer no clear next step. When visitors leave without converting, you’ve paid for clicks that brought no results.
For instance, someone searching for an emergency electrician in Perth wants a phone number above the fold. They need to contact an electrician quickly, so lengthy company details and service lists can get in the way.
Along with a visible phone number, the landing page should deliver what your ad promises. If it doesn’t, the poor experience can hurt your Quality Score and Ad Rank.
Checking Your Conversion Tracking, Smart Bidding and Budget Settings
After reviewing your keywords and landing pages, check your conversion tracking, Smart Bidding and daily budget settings. Problems with these settings can also waste your ad budget, even when your keywords attract the right visitors.
Check these four settings before making any changes to your bids:
- Broken Conversion Tracking: Accurate conversion tracking is important because Google Ads needs reliable data to optimise for customers rather than clicks alone. Check that Google Ads and Google Analytics record conversions correctly, then submit a test enquiry to see if Google Tag Manager fires the right tracking tags.
- Budget Spread Too Thin: When you split a $50 daily budget across five campaigns, each gets just $10. In a competitive search campaign, that may only cover two clicks. Pause the two weakest campaigns so your better-performing ones have more budget to work with. This also makes it easier to manage your Google Ads budgets and bids.
- Bidding Strategy Mismatch: If you switch to Target CPA or Target ROAS before collecting enough conversion data, Google may struggle to meet your targets. These bidding strategies use past conversion data to set bids. For a new account with little data, Maximise Clicks or manual CPC may be a better starting point.
- No Negative Keywords: Review your search terms regularly and add irrelevant searches to your negative keyword list. For example, words like “free”, “jobs” and “DIY” may help block unwanted clicks. But only exclude terms that don’t match what your customers are searching for.
Fix your conversion tracking first so you know which clicks lead to customers and sales. With accurate data, you can measure your cost per conversion and make better decisions about your budget.
PPC Audit Basics: How to Review Each Campaign for Google Ads Optimisation
A simple PPC audit once a month can identify wasted Google Ads spend before it starts draining your account. And you don’t need special software or an agency login to audit Google Ads accounts. Just set a frequent reminder to review your keywords, search terms, conversions and campaign budgets.
The table below shows what to check and how often to review each area.
| Audit step | What to check | How often |
|---|---|---|
| Search terms review | Queries with cost and no conversions | Weekly |
| Keyword match types | Broad match terms pulling junk traffic | Fortnightly |
| Ad copy and landing pages | Message match and cost per click versus return | Monthly |
| Campaign settings | Locations, networks, bidding strategy | Monthly |
Set aside 15 minutes each week to review your Google Ads account. In our experience, these quick checks often save more money than monthly audits (irrelevant search terms can pile up quickly).
Also, keep a dated record of every change you make to your Google Ads account. Reviewing these records will help you see which changes reduced your cost per lead and which had no effect.
You can then use those results to explain your budget decisions, even when a marketing agency manages your campaigns. You’ll also have the data to compare conversion rates across PPC campaigns each month.
Put Your Google Ads Budget Back to Work
Wasted Google Ads spend often comes from problems hiding in reports and settings you haven’t checked recently. Even an hour spent reviewing your account can reveal issues that cost you money.
Open this week’s search terms report, add your first round of negatives, and confirm your conversions fire correctly. These checks take little time and can reduce wasted spend while giving you better data for future budget decisions.
