Knowing how to read your Google Ads report is what separates owners who control their spend from those who just hope the agency is honest. You don't need to understand every column — most of them don't matter. You need five numbers and a sense of what's normal. Here's how to open your account and know within five minutes whether it's working.
The five numbers that matter
Ignore the wall of metrics. These five tell the story:
- Conversions — how many calls or form fills the ads produced. This is the point of everything.
- Cost per conversion (cost per lead) — total spend divided by conversions. The number that decides if you're profitable.
- Click-through rate (CTR) — clicks divided by impressions. Tells you if your ads are compelling.
- Conversion rate — conversions divided by clicks. Tells you if your landing page is working.
- Search impression share — how often you showed up when you could have. Tells you if budget is holding you back.
What normal looks like
Rough guardrails for local service search campaigns (yours will vary):
- CTR: 4–10% is healthy for Search. Under 2% usually means weak ads or bad keyword targeting.
- Conversion rate: 5–15% of clicks turning into leads is a reasonable range. Under 2% points at the landing page.
- Cost per lead: only "good" relative to what a lead is worth to you — do that math from your job value and close rate.
Don't panic over a single day. Look at 30-day windows so the numbers mean something.
The report every owner should check first
Open the Search Terms report (Keywords > Search terms). This shows the actual phrases people typed to trigger your ad — not your keywords, the real searches. This is where waste hides in plain sight. If you see "plumber salary," "free estimate," or a neighboring city you don't serve, you're paying for those clicks. Add them as negatives right there.
Reading the story the numbers tell
Combine the numbers to diagnose:
- Good CTR, bad conversion rate: your ads work but your landing page doesn't. Fix the page.
- Bad CTR: your ads or keywords are off. Rewrite ads, tighten match types.
- Low impression share, limited by budget: you're leaving leads on the table — a good sign to add budget.
- Good everything but no phone ringing: check that conversion tracking is actually firing, or that calls aren't going to voicemail.
Red flags in an agency report
If someone manages your account, watch for reports that lean on vanity metrics — "impressions," "clicks," "reach" — while going quiet on conversions and cost per lead. Big impression numbers are easy to generate and mean nothing on their own. A trustworthy report leads with leads and cost per lead. If you can't find those two numbers, ask for them directly.
A five-minute weekly habit
You don't need to live in the dashboard. Once a week:
- Check conversions and cost per lead for the last 30 days.
- Open the Search Terms report and add any junk as negatives.
- Glance at CTR and conversion rate for anything that fell off a cliff.
That's enough to catch problems early and keep whoever's running the account honest. You don't have to become a Google Ads expert — you just have to know which five numbers to look at, and refuse to be dazzled by the ones that don't pay your bills.
