How to choose a marketing agency

• Start with the work you need. Match your brief to stated capabilities such as SEO, PPC, public relations, branding, web development, or neighborhood outreach.
• Check location and coverage. An office, campaign location, and statewide service coverage are not the same. Verify that the agency currently serves your target market.
• Clarify scope and staffing. Ask which services the agency will handle directly, who will be available for the work, and how delivery will be coordinated.
• Compare proposals. Request a quote; pricing is not listed here. Share your goals, location, and requested services so you can compare scope, deliverables, and communication plans.
• Evaluate fit, not assumed outcomes. Discuss how the agency would approach your needs, then compare its proposed work with your priorities.
