Clicks don't pay bills
If your Google Ads agency sends you a monthly report that leads with "impressions" and "clicks," you should be concerned. Those are activity metrics, not business metrics. Here's why CPA is the only number that matters.
What is CPA and why does it matter?
CPA — Cost Per Acquisition — is how much you spend to get one paying customer (or qualified lead, depending on your model). Not a click. Not an impression. An actual person who picked up the phone, filled out the form, or walked through the door.
Example:
- You spend $5,000/month on Google Ads
- You get 500 clicks (great, right?)
- Those 500 clicks generate 15 phone calls
- Of those 15 calls, 8 are qualified leads
- Of those 8 leads, 3 become customers
- Your CPA: $1,667 per customer
Is that good? It depends entirely on what a customer is worth to your business. If your average customer value is $500, you're losing money. If it's $10,000, you're printing it.
Why agencies report on clicks instead
Because clicks always go up. It's easy to make a report look good when you're measuring activity instead of results. More budget = more clicks = a graph that goes up and to the right.
CPA is harder to manipulate. It forces accountability. If your CPA is going up, something is wrong — and the agency has to explain what.
How to fix your CPA
Based on campaigns I've managed, here's the 80/20:
1. Fix your landing pages. The fastest way to lower CPA is to increase conversion rate on the page you're already paying to send traffic to. One headline change can drop CPA by 30%.
2. Cut the waste. Pull your search terms report. I guarantee 20-40% of your clicks are on irrelevant searches. Add negative keywords aggressively.
3. Track the right things. If you're counting page views as conversions, your CPA looks great but means nothing. Track calls, form fills, and purchases. Use call tracking to verify call quality.
4. Segment by intent. "Refrigerator repair near me" is a different buyer than "refrigerator repair cost." The first one is ready to book. The second is researching. Bid accordingly.
What I track for clients
Every client I work with gets a weekly report that shows:
- Cost per qualified lead (not clicks, not all leads — qualified leads)
- Close rate by channel
- Revenue attributed to ad spend
- Waste identified and eliminated that week
