Google is making changes to how Performance Max (PMax) and Standard Shopping campaigns compete in ad auctions, starting in October. The key shift is that PMax will no longer automatically outbid Standard Shopping campaigns; instead, the highest Ad Rank will determine which ad serves when both campaigns overlap. This adjustment aligns these campaigns with other types in Google’s ad auction system.

Why it matters:
This change could impact advertisers’ strategies during the critical holiday shopping season, offering more flexibility but requiring careful campaign adjustments to maximize success. Google anticipates a neutral or positive impact on performance at the account level and advises advertisers to fine-tune budgets, and targets, and ensure PMax campaigns are optimized with strong asset groups and quality creatives. The goal is to maintain or improve overall account performance while offering more control to advertisers.
Advertisers should be ready to adapt to these updates to maximize their results in this competitive period.
