Google Ads’ Target-Based Bidding Update For Ecommerce

Google Ads has implemented an update affecting target-based bidding strategies for e-commerce, specifically Target CPA (Cost Per Acquisition) and Target ROAS (Return On Ad Spend). This change aims to improve the performance of campaigns that are currently constrained by their budget, pushing them closer to their defined targets. This adjustment could lead to more efficient spending for some advertisers, but also carries potential risks.

The core of the update, rolled out on August 17th, is a recalibration of how Google Ads manages budget-limited campaigns using these target-based strategies. Previously, such campaigns might underperform relative to their set CPA or ROAS targets due to budget constraints. The new system will more aggressively attempt to hit those targets, even if it means potentially increasing the cost per conversion or decreasing the return on ad spend if not carefully managed. Advertisers are advised that this shift could result in higher overall spending if their campaigns are not optimized for the new behavior.

For SEO professionals and marketers running Google Ads campaigns, this update necessitates an immediate review of all Target CPA and Target ROAS strategies, particularly those that have historically been budget-limited. It's crucial to audit campaign performance, budget allocations, and target settings to prevent unexpected cost increases or diminished returns. Proactive adjustments to bids, budgets, or even the targets themselves may be required to maintain desired profitability and campaign efficiency in light of Google's new, more assertive approach to hitting defined targets.
