Principal Harbor

Principal Harbor is a growth marketing agency for small and mid-sized businesses that want leads they can measure, not reports they have to interpret.

We build and run the full organic demand engine: keyword research from Google Search Console and competitor data, pillar content written to match search intent, fast conversion-focused websites and landing pages, Google Business Profile optimization, and structured data that helps search engines and AI assistants understand and cite your pages.

What sets us apart is attribution. Every lead that comes through a site we manage is tied back to the page, channel, and search that produced it, so you see exactly which work is paying off. That is why many of our clients pay us per lead or as a share of closed revenue rather than a flat retainer. When we propose a project, we show the projected demand, the expected cost per lead, and the month the engagement pays for itself.

We also run paid search and social campaigns, build email programs on Klaviyo and similar platforms, and set up the tracking that connects ad spend, calls, forms, and sales in one view. Our team uses AI heavily for research, content drafting, and reporting, with a human reviewing every piece before it goes live.

Clients include home service companies, law firms, financial advisors, real estate professionals, and direct-to-consumer brands. Engagements start with a short discovery call and a written proposal with clear pricing and timelines.

If you want marketing that is accountable for results, we would like to talk.
