Decide first whether you need a specialist or a full service team. If one channel is clearly underperforming, such as email or SEO, a specialist will usually go deeper. If you need paid media, retention, and creative to work together, a full service agency saves you coordinating three vendors.
Ask what the agency is accountable for. Good agencies agree on business metrics like new customer revenue, acquisition cost, or contribution margin, not just platform ROAS or open rates.
Make sure you keep ownership of your ad accounts, Klaviyo account, and data, so you can change agencies without starting again.
Most agencies work on a monthly retainer. One agency’s published guide puts ecommerce marketing management at $5,000 to $30,000 or more a month, with paid media management often charged at 10 to 20 percent of ad spend on top of the spend itself. Specialists cost less: on this list, Blink publishes SEO from £2,500 a month after the first quarter, and Top Growth Marketing publishes paid media from about $2,000 a month.
Many agencies ask for a six to twelve month commitment. Shorter terms exist, so ask before you sign.
Expect a monthly retainer. Specialists on this list publish prices from about $2,000 a month for paid media and £2,500 a month for SEO. Full service growth agencies commonly charge $5,000 to $30,000 or more a month, plus a share of ad spend for paid media.
Hire a specialist when one channel needs fixing, such as email retention or SEO. Choose a full service agency when paid media, retention, and creative need to be planned together and you do not want to manage several vendors.
Business results: new customer revenue, acquisition cost, and contribution margin. Platform metrics like ROAS and open rates are useful, but they should not be the only thing an agency is measured on.
