Greater Budget Control and a Safer DSA Migration – SEM News #2 June 2026

Meta has introduced a feature that allows direct budget assignment to individual ads. The key component of this mechanism is the “Ensure delivery of this ad” option, which enables marketers to strictly define the share of budget allocated to a specific creative.

For Marketing Managers and professionals responsible for media budget profitability, this change redefines the process of testing and risk control:

• Elimination of selection bias in the testing phase: Meta’s traditional approach often favors one creative based on initial, superficial micro-conversions. Enforcing equal allocation allows for statistically significant data collection on customer acquisition cost (CAC) and final revenue for each creative simultaneously.

• Risk of artificially limiting scale: even distribution is optimal only during the insight-gathering phase. Maintaining rigid allocation after identifying winning creatives constrains algorithmic potential, artificially increases conversion costs, and reduces return on ad spend (ROAS).

This new feature is an analytical control tool, not a permanent delivery model. It is designed to eliminate selection bias in the early days of testing, after which budget should be released to avoid costly algorithmic constraints.

Google has postponed the mandatory migration deadline for DSA campaigns to the AI Max format from September 2026 to February 2027. Avoiding forced technological changes directly protects operational stability and company revenues during peak sales periods, including Black Friday.

What Does this Mean for You?

• Stability during Peak Season: rebuilding campaigns during periods of highest bids and transaction volumes posed a risk of losing control over algorithms and declining efficiency (ROAS). The postponed deadline secures the achievement of annual revenue targets reported to the board.

• Operational comfort in Q1: moving the migration to February enables implementation of the new format during a natural post-holiday market slowdown, allowing time for controlled A/B testing.

• Budget security: you gain the space to strategically plan synergy between advertising structure and SEO without time pressure or the risk of sudden increases in customer acquisition cost (CAC).
