The Client

A five-partner Chartered Accountancy firm in Mumbai offering tax filing, GST compliance, audit, and business advisory. They were spending ₹80,000 a month on Google Ads with no CRM and no tracking in place.

The Challenge

Their entire ad budget ran with no way to trace which ads generated which clients. CPL sat at ₹1,200, well above what was profitable, and leads captured on WhatsApp routinely got lost in message threads. The partners had zero visibility into pipeline or marketing performance.

Our Approach

A full Google Ads audit found 60% of budget going to irrelevant search terms. We restructured into three service-specific campaigns, deployed GoHighLevel to auto-capture and tag every lead by service, and set up AI-driven weekly bid and Quality Score optimization.

What We Built

Restructured Google Ads: 3 campaigns (tax, GST, business advisory) with 14 themed ad groups and 42 AI-written ads
A 280-term negative keyword list blocking irrelevant traffic
GoHighLevel CRM with automatic lead capture from Google Ads
AI campaign optimization — weekly bid adjustments and Quality Score work
A monthly attribution report tracking revenue per campaign

The Results

1.3x → 4.8x
Return on ad spend

★★★★★

"For the first time in 6 years of running Google Ads, we actually know what our marketing is returning. The CPL reduction paid for our entire agency retainer in the first month."

— Managing Partner, CA Firm, Mumbai

Key Learnings

Attribution changed everything. Once the partners could see exactly which campaign produced which client, decisions stopped being about gut feel and became about data — and the budget naturally flowed to what was working.
