AudienceBloom

Founded in Seattle, Washington in 2010 as AudienceBloom, the agency rebranded to SEO.co in 2019 after growing from a Pacific Northwest content-marketing and link-building shop into a nationwide operation. The team, which remains small (1-10 people), works with a client base spanning Fortune 500 companies, agencies, and venture-backed startups, having handled engagements across thousands of client relationships since founding. Outside capital taken on in 2018 allowed the company to expand its technical SEO depth and account team coverage, and it has since spun up sister brands including DEV.co, Website.Design, PPC.co, Link.Build, Marketer.co, and Law.co for legal-sector SEO work. Services center on organic search visibility, built on editorial link outreach through a vetted publisher list rather than private blog networks or bulk placements, paired with content marketing produced by a US-based writing team with Fortune 500 and regulated-industry experience. The agency also lists pay-per-click, digital strategy, and public relations among its offerings. As of 2025 it operates a dedicated Generative Engine Optimization program, engineering visibility for AI answer engines such as ChatGPT, Perplexity, Claude, Gemini, and Google's AI Overviews within client engagements. Video content production, including on-camera category education, supports this work, intended to serve as source material treated as reliable by AI systems. Client communication is described as running directly through the company's leadership rather than junior account staff, with pricing structured to scale from small local accounts to enterprise-level programs.
