Google Target Bidding Changes Echo Past Strategies

Google has implemented significant changes to its target bidding strategies, specifically for Target CPA (Cost Per Acquisition) and Target ROAS (Return On Ad Spend), prompting a re-evaluation by paid search marketers. Reva Minkoff, Founder and President of Digital4Startups Inc., discussed these updates during a recent SMX Now webinar, asserting that the paid search industry has experienced similar shifts in the past. Minkoff, drawing on nearly two decades of experience in Pay-Per-Click (PPC) advertising, highlighted that while the current update represents a meaningful change in how advertisers manage these bidding strategies, the underlying principles are not entirely new. Approximately a decade ago, Google's target bidding strategies functioned in a remarkably similar fashion. Previously, these target bid strategies acted more like efficiency safeguards. If a campaign could achieve performance exceeding its set Target CPA or Target ROAS, Google would continue to deliver that superior performance. This meant a campaign with a $10 Target CPA might consistently acquire conversions for as little as $5. Under the new approach, the target is more strictly enforced as a performance benchmark. If an advertiser sets the Target CPA at $10, Google's system will now aim to acquire conversions around that $10 CPA, rather than actively seeking to significantly outperform it. This shift is expected to provide greater predictability for advertisers. The advantage of this new model is that advertisers may find it easier to forecast campaign outcomes, particularly when increasing budgets, as Google's system will strive to maintain performance around a defined efficiency level. However, a notable downside is that campaigns which historically demonstrated performance significantly better than their set targets may experience a reduction in that outperformance advantage. This evolution in Google's bidding logic is not unprecedented. The original implementation of Target CPA, around 2015 and 2016, operated much like the current system. At that time, Google described Target CPA as a strategy designed to set bids such that the average cost per conversion would align with the advertiser's specified target. While individual conversions might cost more or less, the system's objective was to achieve the target on average. A decade later, much of that original logic has been reintroduced into the platform. Although the surrounding advertising ecosystem has evolved dramatically since then, with the emergence of technologies like Performance Max, AI Max, and Demand Gen, advertisers possess prior experience in managing this type of bidding behavior. The core challenge for marketers now is to adapt their strategies to this renewed emphasis on predictable performance rather than consistent overachievement.
