Working with Us

The Business Relationship

Who We Are

Proteus B2B Marketing is a professional services firm specializing in maximizing marketing qualified leads through organic search and content marketing. In 2006, we were the first to specialize exclusively in B2B SEO.

Who We Work With

We work with a wide range of B2B clients in numerous industries. Clients range from the Fortune 500 to mid-size manufacturing and technology firms to smaller, professional service firms.

Initial Engagements with New Clients

Clients typically engage us for a test drive. Usually, that’s through a B2B SEO audit or keyword research and strategy engagement. Our minimum level of initial engagement with new clients is $7,500.

Retainer-Based Agreements

Most clients engage us to do ongoing work after the initial engagement. We do that through a retainer-based agreement that spells out the scope of work and mutual expectations. Monthly retainer levels start at $5,000 per month.


Significant projects, such as a search-driven design-build website engagement or a complete site overhaul, represent separate, periodic material projects outside of the scope of work of normal retainer-based work. These projects are defined and budgeted separately.

Proteus B2B Marketing has been named one of BtoB Magazine’s Top B2B Agencies, and the work of our B2B marketing consultants and has won several Global ReBrand 100 Awards.

We serve B2B clients throughout the United States and Canada. Our firm’s offices are located in West Michigan in the Greater Grand Rapids metropolitan market.
