A full ecommerce marketing agency can cover paid ads, email, SEO, social and creative. However, few teams are equally strong in every channel. Therefore, ask which channels they lead with and which ones they outsource.
Next, look for a clear growth plan tied to your numbers: customer acquisition cost, average order value, repeat purchase rate and contribution margin. In addition, a good agency explains how channels support each other, such as ads feeding email lists.
Questions to ask on the first call
First, ask what they would prioritize in your first ninety days and why. Next, ask who your daily contact is and who does the hands-on work. Then ask how they report results across channels. Finally, request case studies from brands at your revenue stage. As a result, you can compare every candidate on equal terms.
Pricing models to compare
Agencies charge retainers, project fees, a share of ad spend or performance bonuses. Bundled services can look cheaper but hide thin coverage. So ask for a breakdown by channel and compare the hours or deliverables behind each fee. Above all, get every fee in writing.
