The short version
- 01Judge a month by what each customer cost, not by clicks or impressions.
- 02Compare with the same month last year, because seasons distort month-on-month numbers.
- 03A good report says what changed, why, and what happens next.
Most monthly ad reports open with impressions and clicks, because those numbers are big and they usually go up. Neither one pays your bills. A good Google Ads month is one where you can see what each new customer, call or booking cost, and that cost is holding steady or falling.
Here's how we read a month when we're running Google Ads for Utah businesses, and what we'd want you to ask your own agency.
Two real months, to make it concrete. NIMA, a medical aesthetics school in South Jordan, had 367 conversions from Google Ads in December 2023 at $21.99 each, and the dashboard's year-on-year figure shows cost per conversion 14% lower than a year before. Quality Billiards' Pinball campaign brought in 149 phone calls from $2,763.34 of ad spend between April and June 2022, which works out to about $18.55 a call. Both numbers answer the only question that matters: what did a lead cost?
1. Start with cost per conversion
Cost per conversion is your total spend divided by the actions you care about. It belongs at the top of the report. If it's missing, or buried on page six, ask why. Everything else in the report should help explain why that number went up or down.
2. Check what counts as a conversion
A conversion is only useful if it's something a customer did that you'd pay for: a call that lasted long enough to be real, a form, a booking, a sale. If the account counts page views or button clicks as conversions, the cost per conversion looks wonderful and means nothing. Ask for the list of conversion actions and what each one tracks.
3. Compare like with like
Month-on-month comparisons mislead for most businesses because seasons move everything. December isn't November, and a barbecue restaurant's summer isn't its winter. Compare each month with the same month last year, as NIMA's report does, and look at the trend over a few months before you call anything a win.
