10 Google Ads Red Flags That Are Costing You Money

Whether you manage Google Ads yourself or have an agency doing it, there are clear warning signs that scream: money is being burned. On average, 15% of Google Ads budgets are wasted. With poorly managed accounts, that number climbs to 40–60%.

Here are 10 red flags you should check today.

1. Your conversion tracking is broken

This is red flag number one. Without proper conversion tracking, your entire account is flying blind. Google’s algorithms have no data to optimize, you don’t know what’s working, and decisions are based on gut feelings instead of numbers.

What to check: Open Google Ads → Tools → Conversions. Do you have real conversion actions set up (purchase, form submission, phone call)? Does the data match GA4? If not, fix this before doing anything else.

2. Search CTR below 3%

The average search network CTR is around 6.66%. If your campaigns consistently fall below 3%, something is off. Either you’re targeting overly broad keywords, or your ad copy isn’t compelling enough.

What to do: Rewrite your ads. Include the keyword, a unique value proposition, and a clear call to action. Test at least 3 variations.

3. Quality Score below 5/10

Quality Score directly impacts how much you pay per click. With a score of 3/10, you pay 150% more than a competitor with 7/10 — for the exact same position. Google penalizes irrelevant ads.

Fix it: Focus on three factors: ad relevance, expected CTR, and landing page quality. Better segmentation usually helps — smaller, tightly focused ad groups work best.

4. No negative keywords

Running broad match without negative keywords is like leaving the tap running. Your ads show for queries that have nothing to do with your business, and you’re paying for every click.

What to do: Review your search terms report at least once a week. Add negative keywords at both campaign and ad group level.

5. All clicks go to your homepage

Sending PPC traffic to your homepage is one of the most common reasons for low conversion rates. Users search for a specific product or service — and you show them a generic website.

Fix it: Each ad group should have its own landing page that directly answers what the user searched for. Landing page relevance also impacts Quality Score.

6. Wrong location settings

Google Ads defaults to targeting people who show interest in your location — not just people who are there. Result? A Czech e-shop pays for clicks from India or Pakistan.

What to check: In campaign settings, switch location targeting to „People in or regularly in your targeted locations.“ Then check your location report to see where clicks actually come from.

7. You haven’t checked Search Partners

Search Partners is enabled by default. This means your ads also show on third-party websites — often with significantly worse performance and higher costs.

What to do: Segment performance by network (Settings → Segments → Network). If Search Partners aren’t delivering conversions at a reasonable cost, turn them off.

8. ROAS below 2:1

The median ROAS for Google Ads is 3.5:1. If you’re not getting at least two back for every one you put in, you’re probably losing money. Of course, it depends on your product margins, but below 2:1 should trigger alarm bells.

Fix it: Identify campaigns and keywords with the worst ROAS. Pause them or rework them completely. Focus budget where it actually works.

9. You blindly accept Google’s recommendations

Google shows you „recommendations“ and pushes „Optimization Score.“ The problem? These recommendations primarily maximize Google’s revenue, not your profit. Expanding targeting, increasing budgets, enabling broad match — all increase your spend.

What to do: Evaluate each recommendation individually. Only accept those that align with your business goals. Dismiss the rest — a 100% Optimization Score is not the goal.

10. Your agency only reports clicks and impressions

If your agency sends you a report with clicks, impressions, and CTR — but doesn’t cover conversions, CPA, or ROAS — that’s a serious problem. Vanity metrics don’t tell you whether PPC is making you money.

What to expect: Reports should include: conversion count, cost per conversion (CPA), ROAS, Quality Score trends, and specific action items for the next period.
