Meta Ads Deep Analysis

Andromeda + GEM + Lattice (2026)

Meta's delivery stack was rebuilt across three releases:

• Andromeda (Oct 2025) — ad-retrieval ranking model with 10,000× more

model capacity than the previous funnel (Meta Engineering, Dec 2024). Filters the candidate creative set before the auction layer ever sees it.

• GEM (Generative Embedding Model, late 2025) — replaces the feature

pipeline. Creative content embeds directly into the targeting space, which is why "creative is the new targeting" is now mechanical truth not slogan.

• Lattice (rolled out late 2025 / early 2026) — sequence-aware optimizer

on top of GEM that uses user-action sequences to rank candidate ads.

Net effect: creative diversity is now the #1 performance lever. Ads with Similarity Score >60% (per Confect's measured threshold) get retrieval suppression — the algorithm clusters near-identical creatives and silently limits their delivery. 100 minor variations perform no better than 10 genuinely distinct ones. Prioritize concept / angle / format diversity over variant volume.

Creative-as-targeting scoring rubric

When auditing a creative library against Andromeda's retrieval logic, score across these 5 axes (each 0-2, total 0-10):

Score 8-10 = LOW Entity-ID clustering risk. Score 4-7 = MEDIUM risk (some suppression likely). Score 0-3 = HIGH risk (significant retrieval ticket loss).

Entity-ID Clustering Predictor (pre-launch)

Before launch, predict which creatives Meta will cluster. Cluster-mates share retrieval tickets — only one wins per impression opportunity.

Predictor heuristics (apply to every pair of creatives in the launch set):

1. Visual fingerprint — same product hero, same model, same backdrop, same lighting → likely cluster. Different products or different visual identities → likely not a cluster. 2. Headline fingerprint — same first 4 tokens → likely cluster (e.g. "Save 30% on" + "Save 30% off" + "Save 30% — limited time"). 3. Body copy fingerprint — same opening sentence, same CTA verb → likely cluster regardless of middle-body differences. 4. Video hook fingerprint — same 0-3s shot, same voiceover pattern → likely cluster even if the rest of the video diverges. 5. Format mismatch wins — if pair is (static + video) AND visual fingerprint differs, they are not clustered. Crossing format AND visual is a strong diversity signal.

Output: produce a creative-cluster-risk.md deliverable that groups the launch set into predicted clusters, recommends which creative in each cluster should ship and which should be cut or rebuilt, and reports the final pre- launch diversity score (target ≥8/10).

MAPI v25 ASC/AAC Deprecation Detector

Meta Marketing API v25 deprecates the explicit Advantage Shopping Campaigns (ASC) and Advantage App Campaigns (AAC) creation paths — those campaign types are folded into standard Sales / Leads / App objectives where ASC behavior becomes the default configuration. Detection:

• If the account uses MAPI v23 or earlier: ASC/AAC API endpoints will return

deprecation warnings before the v25 cutover. Capture and flag them.

• If the account uses MAPI v25+: confirm that previously-ASC campaigns have

been migrated to the new objective-default model with the equivalent catalog + budget + existing-customer cap settings preserved.

• If creating new campaigns: use the Sales / Leads / App objective + ASC

defaults rather than the legacy ASC/AAC endpoints.

ASC defaults for Sales / Leads / App (2026 behavior)

When Sales / Leads / App objectives are selected, ASC behaviors are now the default. Audit confirms:

• Catalog connection (Sales): product catalog linked and feed health green
• Existing customer cap (Sales): set to 10-25% (default may be too high

for high-LTV brands)

• Advantage+ Audience (all three objectives): on by default; only override

with manual interest stacks for highly restricted categories

• Advantage+ Creative (all three): text / brightness / music enhancements

on by default; if your brand-safety policy requires off, document the exception per ad set

Process

1. Collect Meta Ads data (Ads Manager export, Events Manager screenshot, EMQ scores) 2. Read ads/references/meta-audit.md for full 50-check audit 3. Read ads/references/benchmarks.md for Meta-specific benchmarks 4. Read ads/references/scoring-system.md for weighted scoring 5. Evaluate all applicable checks as PASS, WARNING, or FAIL 6. Calculate Meta Ads Health Score (0-100) 7. Generate findings report with action plan

• em (email): highest match rate signal
• ph (phone): second highest match signal
• fn, ln (first/last name): improves match accuracy
• ct, st, zp (city, state, zip): geographic matching
• external_id: CRM/user ID for cross-device matching
