The Complete Guide to Google Ads Campaign Analysis

Why 90% of Google Ads Analysis Is Wrong

Most advertisers optimize for: CTR, CPC, CPA, Quality Score. These are engagement metrics. None of them measure what matters: revenue per dollar spent.

A keyword with $2 CPC and 5% CTR looks great in Google Ads. But if 80% of the calls it generates are spam, its real cost per qualified lead is $50 — not $2.

Campaign-Level Analysis

Start at the top. For each campaign, calculate:

Ad Group-Level Analysis

Drill into each campaign. Within “General Services,” you might find that the “Water Heater” ad group generates 3× the revenue per dollar vs. “Drain Cleaning.” Shift budget accordingly.

Keyword-Level Revenue Attribution

This is the holy grail. When you can say “the keyword 'emergency plumber near me' generated $12,000 in revenue from 4 qualified calls at $150 CPA” — that's actionable intelligence.

Despora connects CallRail's UTM data (which includes the keyword) with AI lead scoring to attribute revenue at the keyword level.

Mobile vs. Desktop Campaign Performance

Mobile click-to-call generates higher volume but often lower quality (accidental taps). Desktop callers research more and have higher average job values. Despora's device segmentation lets you see:

• Mobile: 24 calls, 10 qualified, $18,000 revenue, $720/lead revenue
• Desktop: 8 calls, 6 qualified, $28,000 revenue, $4,667/lead revenue

Desktop callers are 6.5× more valuable per lead. Adjust bids accordingly.

Building a Campaign P&L Statement

For each campaign, build a simple P&L:

Revenue: $22,000 (from 8 qualified leads) Cost: $1,200 (ad spend) Gross Profit: $20,800 ROI: 18.3× CPL: $150 Revenue per Lead: $2,750

This is the format your CFO or client wants to see — not CTR and Quality Score.

Real-Time Campaign Change Tracking

When you change a campaign (pause it, increase budget, change bids), use Despora's annotations to mark the exact moment. Then compare before/after:

• Leads per week before vs. after the change
• Revenue per week before vs. after
• CPL before vs. after

This proves (or disproves) that your optimization actually worked.
