Do they Set Goals for Their Clients and Achieve Them?

Growth marketing agencies set goals.  Usually these goals fall into one of seven categories:

• Visibility
• Visitors
• Leads
• Customers
• Revenue
• Audience
• Promoters

These are the seven marketing factors that identify if a business will grow.  If a growth marketing agency has a history of improving these seven factors for businesses like yours, they are probably a good fit for your business too.

Does their workflow fit with yours?

Hiring a growth marketing agency should feel like a partnership.  This is different from work with many other kinds of agencies.  Many agencies are looking for a project you want help fulfilling.  They just need a set of requirements or a punch list and a budget.

Working with a growth marketing agency should be a partnership.    A growth marketing agency is not focused on delivering one specific webpage, video, or social media campaign.  A growth marketing agency is focused on moving specific key performance indicators (KPIs) which can respond to any number of campaigns and creative endeavors.  Creating these campaigns means working together to identify what matters now to your business, what does it mean to be "on brand", and what resonates with your target audience.  The right growth marketing agency will meet with you regularly (at least once every two weeks) and fit into your schedule and your work needs.
