Attribution Case Study

Google Ads Case Study

Lead Sources Were Unclear

The business was receiving leads, but it could not identify which campaigns were actually driving them. This made budget decisions feel like guesswork instead of a clear growth plan.

Campaign source became visible from first click to lead record.

Business Context

The account was producing leads, but reporting did not show which campaigns, sources, and ads were actually responsible.

Goal
Clear source visibility

What Was Breaking

  • UTM structure was inconsistent across campaigns
  • Form submissions did not reliably capture source data
  • GA4 and CRM reports were not aligned
  • Budget decisions were being made without source confidence

What Changed

  • Standardized source tracking across campaigns
  • Updated form fields to retain campaign source
  • Aligned GA4 events with lead records
  • Created a cleaner view of which campaigns generated leads

How I Solved It

I rebuilt the source path so each lead could be traced from the original ad click through GA4 and into the CRM. The goal was not more data. The goal was data the business could trust.

One lead. A completely different level of clarity.

An illustrative interface based on the tracking flow implemented in this case.

Before Lead #1048
Attribution incomplete

Lead sourceUnknown

UTM parametersMissing

The lead arrived, but its campaign context was lost.

After Lead #1048
Attribution complete

The same lead now retains its source from click to CRM.

Decision-ready attribution Campaign source can now be compared with the lead record.

Results & Impact

The work created a cleaner decision foundation. The business could see where leads were coming from, compare ad performance against CRM records, and focus budget on campaigns with real lead value.

Need clearer visibility into where your leads are coming from?

I can review your campaign tracking, GA4 setup, lead forms, and CRM source data to identify where attribution is breaking down.
