Agency Before Good Reporting

Reporting approach: « Monthly spreadsheet with random numbers »

Client sentiment: « I see impressions up but… so what? What does that mean for my business? »

Result: Client cuts budget 50%, ends contract

After Structured Reporting

Same client, restructured reporting:

Report shows:

• Organic trafic: +28% vs last month
• Leads: 47 (worth $47K revenue)
• ROI: 320% (every $1 invested = $3.20 revenue)
• Next 3 months forecast: +85% leads expected

Client reaction: « Wow! That’s incredible ROI. Let’s double the budget! »

Result: Budget doubled, contract extended 2 years, client refers 3 new clients
