Intel Brief: The $50K Monthly Leak Nobody Noticed*

A client's Google Ads account was bleeding $50,000 monthly through a single campaign optimization error that three previous agencies had missed. The problem wasn't obvious—their ROAS looked healthy at 4.2x, but our incrementality analysis revealed massive cannibalization.

The Problem: The Branded Search Trap

The client was spending heavily on branded search terms—their own company name and product names. These campaigns showed excellent ROAS (4.2x) and high conversion rates (12%). Every agency report highlighted them as "top performers."

But here's what nobody questioned: Were these campaigns actually driving incremental revenue, or were they just intercepting people who were already going to buy?

The Incrementality Test: Uncomfortable Truth

We ran a geo-holdout test: paused branded search campaigns in specific regions while keeping them running in others. The results were damning: revenue in the holdout regions dropped by only 8%, while ad spend dropped by 100%.

This meant 92% of the conversions attributed to branded search would have happened anyway. The client was paying $50,000 per month to capture demand they already owned. Their organic search rankings were strong enough that most users would have clicked the organic result instead.

The Hidden Cannibalization

It gets worse: The branded search campaigns were also cannibalizing their retargeting campaigns. Users who had visited the site and were being retargeted would search for the brand name and click the search ad instead. The client was essentially paying twice to reach the same person.

The attribution model gave full credit to the last click (the search ad), making it look like a winner. But the retargeting campaign had done the heavy lifting of bringing the user back—the search ad just intercepted them at the last moment.

The Solution: Strategic Budget Reallocation

We didn't eliminate branded search entirely—it still had some defensive value against competitors. But we reduced the budget by 80% and reallocated those funds to:

• Cold prospecting campaigns targeting new audiences
• Competitive conquest campaigns targeting competitor brand terms
• Content marketing initiatives to drive organic brand awareness

The Results: $40K Monthly Savings + Higher Growth

By cutting the non-incremental branded search spend, we saved $40,000 per month with minimal revenue impact. That budget was redirected to truly incremental channels, resulting in 23% revenue growth over the next quarter.

The lesson: High ROAS doesn't mean high incrementality. If you're not testing what happens when you turn campaigns off, you're flying blind. Most companies are wasting significant budget on campaigns that look good in reports but don't actually drive incremental growth.
