Solving the Performance Max Black Box Problem

Let's be honest—Performance Max feels like a total black box.

Google tells you it's "optimized," but when you're investing significant ad spend, these questions keep you up at night:

• Where are your conversions actually coming from?
• What's driving results vs. draining budget?
• Are you even targeting the right audience?
• Which assets are performing and which are failing?

If you've struggled with these questions, you're not alone. Performance Max campaigns have become a critical part of the Google Ads ecosystem, but their lack of transparency makes optimization nearly impossible.

Fortunately, there's a solution that can transform how you manage and optimize these campaigns.

Introducing the Performance Max Insights Script

This powerful Google Ads script gives you unprecedented visibility into your Performance Max campaigns by breaking down performance data that Google doesn't readily provide in the standard interface.

I've audited over $1 billion in Google Ads spend—and this script has been part of almost every one of those audits recently.

What This Script Reveals:

• Complete channel breakdown: See exactly how your budget is split between Search, Shopping, Display, and YouTube
• Asset-level performance data: Identify which specific assets are driving conversions vs. wasting spend
• Conversion pathway analysis: Understand the full customer journey that leads to your conversions
• Audience insights: Discover which audience segments are responding to your ads
• Targeting opportunities: Find new targeting options you might be missing

The most surprising part? Most PPC specialists have never even used it.

I've watched Google Ads professionals transform their campaign results overnight after implementing what this script reveals:

• Some slashed wasted spend by 50% in a week.
• Others uncovered hidden opportunities that doubled their ROAS.
• Many have used the insights to prove their value to clients and secure larger contracts.
