High-value ecommerce rarely converts on the first touch. Longer sales cycles, larger purchase considerations, and varying deal sizes mean in-platform performance often underrepresents true business impact. To scale effectively, optimization must reflect expected value, not just immediate results.

We rolled out AI Max for Search across campaigns for clients in multiple verticals, including eCommerce, online education, and nonprofit. In most cases, it captured 5–10% of Search spend, produced ~30% stronger ROAS than non‑AI Max traffic, and uncovered incremental volume. However, it also proved to “cherry-pick” volume from existing keywords, which masked some inefficient spend, emphasizing the need for strong conversion signals and constant guardrails.
