PMax asset group reviewer

Performance Max hides most of its levers, so structure is what you control. This skill checks that each asset group has a clear product set, a matching message and enough assets to run.

When to use

  • After a new PMax launch has run 3–4 weeks.
  • When PMax spend grows but Shopping-like ROAS falls.

Input

Per campaign: budget, bidding (tROAS / max conversion value), target, and brand exclusions. Per asset group: listing group tree, audience signals, final URL expansion setting, asset counts (headlines, long headlines, descriptions, images, logos, videos) and asset-level performance ratings. Product-level performance by asset group for 30 days.

Checks

  1. Listing groups. Each asset group should subdivide by one dimension (custom label, product type, brand) and cover a coherent set. Flag an "All products" group sitting next to specific ones in the same campaign; flag products appearing in two campaigns, since only one will serve.
  2. Assets. Minimum to run well: 5 headlines (up to 15), 1–5 long headlines, 2–5 descriptions (one ≤ 60 chars), landscape and square images, a logo, and a real video (otherwise Google auto-generates one). Flag "Low" rated assets older than 30 days.
  3. Message match. Headlines should name the product set in the listing group; a generic brand message on a category group is a finding.
  4. Signals. Customer-list and search-theme signals should differ per group; identical signals everywhere add nothing.
  5. Final URL expansion and brand. Note whether expansion is on and whether brand terms are excluded; report, do not judge, if the store has no stated policy.
  6. Zombies. Share of products with zero impressions per group; above 40% suggests a separate zombie campaign.

Rules

  • Read-only. Recommendations only; no asset, listing group or budget change is made.
  • Asset-level conversion data is not available in PMax; do not invent it. Use ratings and product-level data.
  • Missing exports are listed at the top of the report.

Output format

Campaign "PMax – Footwear" · tROAS 400% · 30d ROAS 3.1
| asset group | products | zero-impr. | headlines | video | finding |
| Trail – m-high | 184 | 22% | 11 | yes | ok |
| All products | 2 040 | 61% | 5 | auto | catch-all overlaps Trail; split by label_1 |
Next: move 1 240 zombie products to a separate low-budget campaign.
