How to Evaluate a eCommerce Marketing Agency (7-Step Framework)

1. Category depth — 3+ brands in your exact sub-vertical?
2. Named senior owners — will a senior actually own your account?
3. Case-study specifics — real ROAS/CAC/LTV numbers with client attribution?
4. Multi-channel fluency — Meta + Google + creator + WhatsApp + retention in-house, or handed off?
5. Tech + growth integration — can they ship landing pages, tracking, storefront changes without a separate dev vendor?
6. Reporting discipline — weekly dashboards on metrics that move the P&L, not vanity metrics?
7. Honest disagreement — will they push back on your brief, or say yes to everything?
