Sonar Digital

Sonar is a full-service digital marketing, advertising and analytics agency based in Portland, Maine. 

We combine search engine optimization (SEO), web analytics, pay-per-click (PPC) advertising and social media marketing to drive dynamic results.

What even is “marketing” anymore—legacy, digital, search, omni-channel? The labels blur, but the mandate is crystal clear: create momentum that lasts. At Sonar, nearly fifty years of combined experience have taught us that sustainable growth isn’t a campaign or a channel, it’s a disciplined practice of isolating patterns, shaping clear strategy, and orchestrating every touchpoint so progress compounds.

Yes, we can optimize your site, spike traffic or lower your CPA, but we’d rather blueprint the engine that keeps pushing revenue forward long after the first wins. We start by identifying where opportunity lives: in the data, the market, the story you tell. Then we design the structure that turns insight into action—aligning teams, technology, and message—to meet consumers at the most meaning moments, across mediums and channels.

The result? Growth that feels inevitable instead of accidental. If you’re ready to move beyond piecemeal fixes and toward a system built for both today’s sprints and tomorrow’s marathons, we’re here to connect the dots and clear the path.
