Google Ads Assets

Google Ads — Assets (shared creative)

One creative generator used by every builder, so copy rules and voice live in one place. Reads account-context.yaml (voice, brand, offers, vertical) and the data source (best sellers, real prices).

Operating rules

• Pull voice/positioning/offers from context — no generic filler, no off-brand claims.
• Enforce character limits and policy/trademark rules. Never put a competitor trademark in ad text.
• Use REAL product names/prices/stock from the data source; don't invent.

Model dispatch (run cheap, decide expensive) — see ${CLAUDE_PLUGIN_ROOT}/references/model-tier-dispatch.md

• Scout (haiku) — pulling real product names/prices/stock from the data source; the Google-accurate char-count + ready-to-copy wrapping pass.
• Judge (main session) — all copywriting (headlines, descriptions, long headlines, search themes, sitelinks, briefs), voice/positioning, policy/trademark safety, pin discipline. Creative is the one thing that never goes to a cheap tier; only the inputs (product facts) and the validation (char count) do.

STEP 1 — RSA (Search / Branded)

Per ad group: up to 15 headlines (≤30) and 4 descriptions (≤90), themed to the ad group's intent. Mix angles: keyword/intent · offer (shipping, selection, in-stock) · qualifier (professional/wholesale/ bulk or value, per vertical) · best-seller names · trust/social proof · CTA. Pin only must-include/legal claims (over-pinning kills RSA flexibility). Aim for Good/Excellent ad strength.

STEP 2 — PMax asset-group copy

Per asset group: 15 headlines (≤30), 5 long headlines (≤90), 5 descriptions (≤90; #1 ≤60), and up to 50 search themes (raised from 25 in 2025; distinct per AG, no overlap). Use the angle mix in ${CLAUDE_PLUGIN_ROOT}/references/pmax-best-practices.md.

STEP 3 — Demand Gen briefs

Image + video briefs by spec (sizes + shot list + CTA). Combined image+video outperforms video-only. Provide concrete direction (subject, context, composition, lighting, on-screen text/CTA) per format.

STEP 4 — Extensions

Sitelinks (text ≤25; two descriptions ≤35 each; live URL), callouts (≤25), structured snippets (value ≤25). Level depends on campaign type: in PMax these attach at the campaign level (spec.extensions), never the asset group. In Search, they may be campaign- or ad-group-level (ad-group only when groups differ enough to warrant distinct links). See builder-pmax STEP 7b.

Validation

Count characters the Google way (NFC-normalized, CJK/full-width = 2, no trailing/hidden whitespace) per ${CLAUDE_PLUGIN_ROOT}/references/google-ads-formatting.md — not naive len(), which lets copy pass here but get rejected on entry. Flag off-brand/banned phrasing or competitor trademark in text; confirm product references are real (in stock, correct price). Keywords/negatives come back ready-to-copy wrapped ([exact] / "phrase" / broad). Return assets keyed by campaign type + group for the builder to drop into campaign-spec.json.

To build / refine later

• [ ] Optional AI image generation hook for Demand Gen / PMax visuals.
• [ ] Shared char-limit/policy validator reused by builders.
