For many, the black box of channel insights has begged the question; "What’s the point of Performance Max if 95% of conversions come from Search?"
In a lot of Google Ad accounts we’ve worked on, when you look at Channel Performance, the majority of conversions often do sit with Search. But we think that misses the bigger picture.
Performance Max isn’t just about where the conversion happens. It’s about how the conversion happens. Even if Search is taking the credit, Performance Max is still doing a lot of heavy lifting behind the scenes:
• Full-Funnel Coverage
PMax allows you to reach users across Google's entire network, YouTube, Display, Discover, Gmail, and Maps, not just when they’re actively searching, but earlier in their journey.
• Incremental Reach Beyond Search Demand
Search only captures existing intent. PMax helps you tap into new audiences who haven’t searched yet.
• Assisted Conversions (That You Don’t Always See Clearly!)
YouTube or Display impressions often act as touchpoints that influence later Search conversions.
• Stronger Audience Signals & Machine Learning
PMax leverages first-party data, intent signals, and automation to find converting users you might not target manually.
• Creative & Messaging Testing At Scale
It continuously tests combinations of headlines, descriptions, images, and video, something that would be near-impossible to replicate manually.
• Holistic Auction Coverage
PMax can enter auctions you’re not eligible for (or not prioritising) in standard Search campaigns.
• Efficiency Through Automation
When structured properly, it reduces the need for heavy manual optimisation while still driving performance.
Search may close the deal. But PMax often helps create the opportunity. The real question isn’t “Why is Search getting the conversions?” it’s “Would those conversions exist without the wider PMax ecosystem?”
