Google Performance Max - The Campaign Type That Forced NZ Advertisers to Rethink Everything

In 2023, Google made Performance Max campaigns mandatory by merging Smart Shopping campaigns into the Performance Max framework. For New Zealand advertisers, this wasn't just another update - it fundamentally changed how ecommerce businesses approach Google Ads.

What Changed

Performance Max replaced the campaign types that gave New Zealand advertisers granular control. Smart Shopping and Local campaigns were sunset, forcing migration to a system where Google's AI controlled targeting, placements, and budget allocation across all Google properties simultaneously - Search, Display, YouTube, Gmail, Discover, and Maps.

The shift represented a philosophical change: from advertiser-controlled targeting to algorithm-controlled performance. For NZ businesses accustomed to manually selecting where ads appeared and who saw them, this loss of control felt uncomfortable.

Early results were mixed. TransUnion data showed Performance Max delivered 19% higher ROAS than automated social platform campaigns for retail advertisers. However, this performance came with trade-offs - reduced transparency about where budget was spent and limited ability to exclude poor-performing placements.

The NZ Implementation Challenge

For small NZ businesses with limited budgets, Performance Max created a dilemma. The algorithm required substantial data to optimise - often $500-$1,000 in spend before meaningful performance emerged. Splitting already-modest budgets across multiple campaigns meant none achieved sufficient data for optimisation.

The strategic answer: consolidation. Rather than running separate campaigns for different product categories or audiences, Kiwi advertisers needed to trust Performance Max with broader authority and larger daily budgets.

What We Learned

Asset diversity matters more than you think: Performance Max requires multiple asset types - headlines, descriptions, images, videos, logos. Brands that provided diverse, high-quality assets outperformed those with minimal creative.

Product feed is your foundation: Clean, detailed product data became non-negotiable. Investing in feed optimization delivered better returns than increasing ad spend.

Let go of manual control: Fighting the algorithm by trying to force specific behaviours typically underperformed. The brands that succeeded were those willing to let AI find patterns they couldn't see manually.

Budget thresholds are real: Performance Max wasn't effective at $20/day budgets. NZ businesses needed to allocate at least $50-75/day to see the algorithm optimise properly.

Performance Max set the template for Google's automation-first future. It signaled that manual campaign management would become increasingly secondary to providing the AI with quality inputs (assets, product data, conversion tracking) and letting machine learning handle optimization.
