USA Internet Marketing — Market Notes
At boutique agencies under 20 employees, the founder or managing director makes all tool and vendor purchasing decisions. At mid-size agencies (20-100), department heads (Head of SEO, Head of PPC, Creative Director) evaluate and often control their department's tool budget. Agencies are sophisticated software buyers who evaluate tools on ROI for their clients, not just their own workflow.
Marketing agency outreach works best when framed around client deliverables rather than internal efficiency — agencies think in terms of what they can deliver to clients, not what makes their own life easier. Tools that agencies can resell, white-label, or use to generate visible client ROI are significantly more attractive than internal productivity tools. Agency owner/founder communities (Agency Mastermind, Smart Agency Masterclass) are important trust-building networks.
