Aug 17 tCPA / tROAS Update — Campaign Risk Scan

Google is changing how budget-limited Target CPA / Target ROAS campaigns bid starting August 17, 2026 — campaigns currently beating their target will drift toward it (higher CPA / lower ROAS) unless the target is adjusted first. Last 30 days · active campaigns only (status = Enabled and delivering spend in the window) · scanned across all AEX + hosted client accounts.
Data limitation: Windsor.ai / the Google Ads API does not expose a direct "Limited by budget" serving-status field for this pull, so this table can't confirm which campaigns are actually budget‑constrained (a precondition for the update to apply). The "gap" column shows how far actual CPA/ROAS is beating or missing target — a necessary but not sufficient signal. Treat "High" tier campaigns as the ones worth checking budget status on in the Google Ads UI (or the new Bid Target Adjustment Tool) before acting. Campaigns with fewer than ~10 conversions in the window are flagged as low-volume — the gap % there is noisy and shouldn't drive a target change on its own.
