SEO.co

Headquartered in Seattle, Washington, with a second office in West Palm Beach, Florida, SEO.co has operated since 2010, working with both Fortune 500 companies and venture-backed startups, as well as agencies seeking white-label support. The team, sized between 1 and 10, positions itself as a technical SEO agency adapted for search across Google as well as AI answer engines such as ChatGPT, Perplexity, Claude, and Gemini. Client industries referenced include enterprise, legal, SaaS, and dental sectors, alongside general small and mid-sized business markets. The agency's declared services span search engine optimization and content marketing, delivered through offerings including technical SEO, link building, on-page SEO, local SEO, SEO audits, content writing, PPC management, public relations, and AI SEO/generative engine optimization (GEO/AEO). Its stated method combines three elements: a technically sound website, content matched to search intent, and authority signals intended to build trust with both traditional search engines and AI systems, run together as what the company describes as a single operating system rather than separate campaigns. SEO.co also provides free diagnostic tools, including a backlink checker, broken link checker, site audit, sitemap validator, site speed tester, title tag checker, and robots.txt tester. New inquiries are directed through a contact process that includes a free initial diagnostic and a response within one business day, with services scoped by monthly budget tiers ranging from under $2,000 to over $25,000 per month.
