How to Tell If Your Google Ads Are Underperforming
If you are spending money on Google Ads and cannot point to a clear return, something is wrong. After auditing over 100 accounts, these are the warning signs we see most often. The average account we audit wastes 25% of its monthly budget.
First, here are the benchmarks to evaluate your account against.
| Metric | Poor | Average | Good | Excellent |
|---|---|---|---|---|
| Click-through rate (Search) | Below 2% | 2-4% | 4-6% | Above 6% |
| Conversion rate | Below 2% | 2-5% | 5-10% | Above 10% |
| Cost per lead (home services) | Above $150 | $75-$150 | $30-$75 | Below $30 |
| Cost per lead (medical) | Above $200 | $100-$200 | $50-$100 | Below $50 |
| Quality Score | 1-4 | 5-6 | 7-8 | 9-10 |
| Impression share | Below 20% | 20-40% | 40-70% | Above 70% |
"The first thing I check when someone says 'Google Ads does not work for my business' is their conversion tracking. Nine times out of ten, the issue is not the platform. It is account management. Google Ads works for nearly every service business when it is set up correctly." - Brock Olsen, Paid Media Strategist
Sign 1: You Are Getting Clicks but No Leads
High clicks with no conversions points to a landing page problem. Your ads are attracting the right people, but your website is not converting them. Common causes include sending traffic to your homepage instead of a dedicated landing page, slow page load times, no clear call to action above the fold, and forms that ask for too much information.
Fixing landing page issues alone can cut cost per lead by 30-50%. This is often the highest-impact fix in any account. If your conversion rate is below 3%, start here before touching anything else in your ads account.
Sign 2: Your Search Terms Report Is Full of Junk
Your search terms report shows the actual queries that triggered your ads. If it is full of irrelevant terms, you are paying for clicks from people who will never become customers.
Examples we find in nearly every audit: a plumber showing up for "plumbing school near me," a roofer paying for "roofing materials wholesale," and a therapist getting clicks from "free therapy worksheets."
82% of underperforming accounts we audit have no negative keyword strategy. The fix is straightforward: review your search terms report weekly and add negative keywords for irrelevant queries. If you have never done this, there could be months of waste built up in your account.
Sign 3: Your CPC Keeps Climbing
If your cost per click is increasing month over month without a corresponding increase in lead quality or volume, something is going wrong. Common causes include Quality Score degradation (your ads and landing pages are becoming less relevant), increasing competition in your market, and ad fatigue (the same ad copy has been running too long).
The fix depends on the cause. Check your Quality Scores first. If they are dropping, your ad relevance and landing page experience need attention. If competition is the issue, focus on improving Quality Score to reduce costs while maintaining position.
Sign 4: You Cannot See Conversion Tracking Data
If your Google Ads dashboard shows zero conversions, or if you cannot tell which keywords are generating leads, your tracking is broken. This means every optimization decision in your account is a guess.
What should be tracked: phone calls from ads, form submissions, and chat conversations. Verify this by checking Tools > Conversions in your Google Ads account. If the status says "No recent conversions" or "Inactive," your tracking needs to be fixed immediately.
Sign 5: Your Agency Only Reports on Clicks and Impressions
Clicks and impressions are activity metrics, not results metrics. If your monthly report from your agency focuses on how many impressions your ads received or how many clicks you got, they are reporting on inputs, not outcomes.
Your reports should include: total leads (calls + forms), cost per lead, lead quality assessment, and revenue impact when possible. If your agency cannot tell you your cost per lead, they are either not tracking conversions or not managing for results.
"When someone comes to us after a bad experience with another agency, the first thing I ask is 'What did your reports look like?' If the answer is a PDF with impressions and click counts but no lead data, I already know the problem. Those agencies are selling activity, not results. The reporting is designed to look busy." - Leo Speaks, Sr. Account Manager
Sign 6: Your Ads Show Outside Your Service Area
Check your geographic targeting. Go to Settings > Locations in your Google Ads account. Two things to verify: you are targeting only your service area, and your location option is set to "Presence" (people in your area), not "Presence or Interest" (people interested in your area).
The "Presence or Interest" setting is the default, and it can waste 10-40% of your budget by showing ads to people who are searching about your area but are not located there. A Seattle plumber does not need clicks from someone in Florida researching "Seattle plumbing costs."
Sign 7: Nothing Has Changed in Your Account for Months
Google Ads requires active management. Check your account's change history (go to Change History in the left menu). If there are no changes for weeks at a time, nobody is optimizing.
What active management looks like: weekly search term reviews, regular negative keyword additions, ad copy tests, bid adjustments based on performance, and budget reallocation to top-performing campaigns. If none of this is happening, your account is on autopilot.

| Clicks but no conversions | CVR below 1% | Landing page or offer problem | 30-50% of budget | High |
| Irrelevant search terms | Unrelated queries triggering ads | No negative keywords | 15-25% of budget | Easy |
| Rising CPC, flat results | CPC increasing month over month | Quality Score or competition issue | 10-30% of budget | Medium |
| No search term reports | Agency never reviews them | Set-and-forget management | Unknown | Easy |
| Geographic waste | Clicks from outside service area | Targeting too broad | 10-40% of budget | Easy |

Frequently Asked Questions
How much money am I wasting on Google Ads?
The average account we audit wastes 25% of monthly spend. On a $3,000/month budget, that is $750/month or $9,000/year. The biggest waste sources are irrelevant search terms, broad geographic targeting, and poor landing pages.
Should I pause my Google Ads if they are not working?
Not immediately. First, diagnose the problem. If the issue is fixable (negative keywords, landing page, tracking), fix it while ads are running so you can measure the improvement. Only pause if the account needs a complete rebuild.
How do I find out what search terms trigger my ads?
In your Google Ads account, go to Keywords > Search Terms. This shows the actual queries people typed before clicking your ad. Review this report weekly and add irrelevant terms as negative keywords.
Can a poorly managed Google Ads account be fixed?
Almost always, yes. Most issues are structural: negative keywords, match types, landing pages, and tracking. These can be fixed within a few weeks. The more fundamental the issues (like complete lack of conversion tracking), the more time it takes to rebuild with proper data.
What is a reasonable cost per lead for Google Ads?
It depends on industry. Home services: $30-$150. Medical: $50-$200. Therapy: $30-$80. The key question is whether your cost per lead allows profitable customer acquisition. Use our budget guide for industry benchmarks.
How do I know if my agency is doing a good job?
Ask for cost per lead data (not just clicks and impressions). Check the change history for regular activity. Ask to see the search terms report. A good agency will be transparent about all three. If they cannot or will not share this data, that is a red flag.
