How to Measure Google Ads Performance: 6 Metrics, 1 Scorecard
The report arrives: clicks up, impressions soaring, click-through rate climbing. The charts are green. But the phone rings just as often as before. The report is accurate — it’s just measuring the wrong things. 📊
Google Ads performance measurement uses six metrics: enquiry count, cost per enquiry, conversion rate, spend pacing, search-term quality and return on ad spend. Clicks and impressions are intermediate metrics; decisions aren’t made with them.
This guide covers the six metrics, the scorecard format, the misleading numbers and the measurement infrastructure. Read your report alongside it. 🧮
The 6 Metrics in Google Ads Performance Measurement
BU BÖLÜMÜN ÖZETİ
- Metrics 1-2: enquiries and cost
- Metric 3: conversion rate
- Metrics 4-5: pacing and term quality
- Metric 6: return on ad spend
The panel has hundreds of columns; six suffice for decisions. 📏
Google Ads performance measurement reads through: (1) enquiry count — forms, calls and messages combined, (2) cost per enquiry, (3) conversion rate — clicks becoming enquiries, (4) spend pacing, (5) search-term quality — the share of relevant searches, (6) return on ad spend for e-commerce.
Metrics 1-2: enquiries and cost
Read together: enquiries rising while cost falls is genuine improvement.
Metric 3: conversion rate
A low rate is usually the landing page’s problem, not the ad’s.
Metrics 4-5: pacing and term quality
Is budget spent on schedule, and does the money go to relevant searches? The second shows in the search-term report.
Metric 6: return on ad spend
The core metric in e-commerce; for service businesses its place is taken by cost per enquiry. 💰
How to Build the Google Ads Scorecard
BU BÖLÜMÜN ÖZETİ
- The baseline
- One sentence per number
- Bad news gets written too
- The rule of three priorities
Six metrics on one page. Fixed format, regular date. 📄
The scorecard has four blocks: this month’s numbers, change versus last month, the month’s work, and next month’s three priorities. The same format repeats monthly; comparability beats beauty. Without a scorecard, management becomes storytelling.
The baseline
Without pre-engagement values, improvement stays a claim.
One sentence per number
A single line under each metric: why did it move? An uncommented table goes unread.
Bad news gets written too
A report where every metric rises every month is selected data, not reality.
The rule of three priorities
Maximum three tasks for next month. A long list means none get finished. 🎯
4 Misleading Numbers in Google Ads Reports
BU BÖLÜMÜN ÖZETİ
- Impressions
- Click-through rate
- Position obsession
- Low-quality conversions
Some metrics look good but produce no decision. Watch four. 🎭
The misleading numbers: impressions (being seen doesn’t sell), click-through rate (wrong people clicking also raises it), average-position obsession (top spot isn’t always profitable) and total conversions (leads whose quality was never separated). The antidote to all four is the same: cost per enquiry.
Impressions
Outside brand-awareness campaigns, meaningless alone.
Click-through rate
A high rate can come from irrelevant but curiosity-baiting copy — and it burns budget.
Position obsession
The top spot is the most expensive one; profitability often sits at second or third.
Low-quality conversions
Not everyone who fills a form is a prospect; quality feedback from sales belongs on the scorecard. 🔄
Building the Google Ads Measurement Infrastructure
BU BÖLÜMÜN ÖZETİ
- Site conversions
- Phone tracking
- Offline feedback
- Tagging discipline
Metrics only mean something with correctly built measurement. Four components. 🔧
The infrastructure has four parts: site conversion tracking (forms, cart, sales), phone tracking (click-to-call and number measurement), offline feedback (which enquiries became sales) and source tagging. In SME accounts the most commonly missing piece is phone tracking.
Site conversions
Every important action measured separately; definitions at Google Ads Help.
Phone tracking
If most sales close by phone, unmeasured calls mean invisible success.
Offline feedback
Which enquiry became a sale? Fed back, campaigns start optimizing for quality.
Tagging discipline
Messy source tags make messy reports; waste diagnosis in why budget disappears. 🏷️
Field Notes 📝
The most striking moment in scorecard work is when the sales team’s quality feedback first enters the table. A campaign that looked “cheap” in the panel produces leads that never close, while the “expensive” one brings the actual business. Budget changes seats in that meeting.
Quick Glossary 📖
Cost per enquiry: the ad cost of one lead. Conversion rate: clicks becoming enquiries. Offline conversion: feedback on enquiries that became sales. Baseline: the pre-improvement measurement.
