To identify the right partner, evaluate agencies against the following criteria:

Ecommerce-specific experience
Look for proven results tied to revenue growth, funnel optimization, or ROAS across different eCommerce platforms.

Strong agencies track ROAS, CAC, LTV, and conversion rates. Small technical wins matter: improving site speed by one second can boost conversions by up to 17%.
Multi-channel expertise
Ensure they can manage SEO, PPC, paid social, email, and CRO together. Diversifying channels protects growth if ad costs spike or a platform underperforms.
Conversion rate optimization (CRO) focus
Ask about A/B testing, product-page optimization, checkout fixes, and mobile UX.
Transparent reporting & communication
Expect clear KPIs, regular updates, and accessible dashboards.
Tailored strategy for your business model
The agency should adapt its approach to your audience, margins, price point, and growth stage

What questions should I ask before hiring these types of agencies?

Before you hire an agency in the U.S., focus your questions on these essential areas:

How do you handle tracking, analytics, and attribution to ensure reporting accuracy across platforms?

How many specialists will work on my account, and what relevant experience do they have with similar ecommerce stores?
What performance timeline should I expect for testing, optimization, and achieving consistent ROI?

What are the key KPIs to track for eCommerce marketing success?
