SEO.co expands into San Francisco to target enterprise search demand

SEO.co has opened in San Francisco, and the move says as much about where agency demand is heading as it does about one company’s footprint. The Seattle-founded firm, which says it has served clients since 2010, is using the Bay Area expansion to reach businesses with the kind of search problems that do not get solved with a few blog posts and a basic keyword list.

The company says its San Francisco focus includes local SEO, technical SEO, content and link building, and enterprise SEO. In its expansion materials, SEO.co also highlighted Generative Engine Optimization, authority link acquisition, AI search visibility, technical SEO audits and content marketing, a mix aimed squarely at technology and SaaS brands that need measurable programs built for scale. SEO.co says it works with both local California businesses and national companies, including small businesses and Fortune 1000 clients.

That positioning matters because the search stack has changed fast. Google began rolling out AI Overviews to users in the U.S. in May 2024 after saying the feature had already been used billions of times in Search Labs. OpenAI followed with SearchGPT as a temporary prototype on July 25, 2024, testing AI search features designed to deliver fast, timely answers with clear and relevant sources. For agencies, that has pushed search strategy beyond traditional blue-link rankings and into a world where visibility has to survive generative answers, source citations and shifting discovery paths.

San Francisco is a logical place to make that bet. CBRE said the Bay Area had the most AI tech talent in North America in 2025, with 76,079 workers, up from 61,497 in 2024. The firm also said the region attracted three-quarters of U.S. AI venture capital funding since 2019 and led its tech talent rankings for the 12th consecutive year. That concentration of talent, capital and hyper-competitive software companies creates exactly the kind of client market where enterprise SEO, link strategy and AI-aware content systems can command serious budgets.

The expansion lands against a mixed local backdrop. The City and County of San Francisco’s May 2025 economic report said tech employment continued to decline even as downtown activity recovered and unemployment fell to 3.7 percent. That tension, shrinking legacy tech employment alongside renewed activity in the core, helps explain why service firms are still leaning into the city. SEO.co’s move reads less like routine territory expansion and more like a signal that the agencies with real execution are chasing denser markets, deeper specialization and the next version of search itself.
