Alongside core SEO it runs dedicated generative engine and answer engine practices covering ChatGPT, Claude, Perplexity, Gemini, Copilot and Google AI Overviews.
Victorious publishes separate GEO and AEO service lines with platform-specific pages for Claude, ChatGPT, Perplexity, Gemini and Copilot, and lists a San Francisco address on its own contact page. Its about page reports five-time search agency of the year recognition.
You want a search-only agency with a fully built out AI search practice and have enterprise-level budget.
- Lists a San Francisco address on its own contact page and has focused only on search since 2013
- Runs dedicated GEO and AEO pages, including platform-specific pages for six AI surfaces
- Clutch profile shows 4.8 out of 5 across 119 reviews
- Clutch lists a 50,000 dollar minimum and a 300 dollar hourly rate, out of reach for small budgets
- Pricing is not published and is scoped only after an audit
Siege Media
Siege Media is a content marketing and SEO agency whose about page lists four offices, including San Francisco on Post Street, alongside Austin, New York City and Chicago. It describes its team as creatives, marketers and search experts working to help brands drive visibility on and off LLMs, and it offers a dedicated GEO service.
Siege Media lists a San Francisco office address on its own about page and runs a named GEO service built around research reports, digital PR, bottom-of-funnel content, and community presence. Its founder authored a book on generative engine optimization.
You want AI search visibility earned through content, original research and digital PR rather than technical work alone.
- Lists a San Francisco office among four US offices
- GEO is a named service with concrete deliverables including research reports and digital PR
- Clutch profile shows 4.9 out of 5 across 48 reviews
- Its about page identifies San Diego as the main headquarters, so San Francisco is one of several offices

Previsible
Previsible was founded in 2020 in San Francisco and Santiago by Jordan Koene, Tyson Stockton and David Bell, with Koene having previously served as CEO of Searchmetrics. It offers SEO strategy, technical SEO, content marketing, authority building and a dedicated GEO practice covering ChatGPT, Claude, Gemini, AI Overviews and Copilot.
Its contact page lists a San Francisco office in the Mission district, and its about page confirms San Francisco as global headquarters with a second office in Santiago, Chile. GEO strategy is one of five named services, split into content and placement strategy, visibility and measurement, and implementation.
You want an SEO team with deep search industry pedigree that treats AI visibility as a measurable growth channel.
- Confirms San Francisco headquarters with a Mission district street address on its own site
- Founded by a former Searchmetrics CEO along with two other search industry veterans
- GEO is a named service with defined measurement and implementation tracks
- Only one Clutch review, so third-party validation is thin despite the 5.0 score
- The team is distributed across roughly ten countries, so day-to-day staffing may not be local
AdLift
AdLift is a digital marketing agency established in 2009, led by CEO Prashant Puri, with offices in the US and India and campaigns across North America, Europe and Asia. It lists SEO, generative engine optimization, answer engine optimization, content marketing, paid media, social media and influencer marketing among its services.
Its contact page lists a Bay Area office in Burlingame, and its homepage names GEO and AEO as distinct services, describing GEO as appearing in AI-generated summaries on ChatGPT, Gemini and Perplexity, and AEO as structuring content to win featured snippets, voice results and AI direct answers.
You want one Bay Area agency covering SEO, GEO and AEO plus paid and social under a single roof.
- Publishes a verifiable Bay Area street address in Burlingame, close to the airport
- Names both GEO and AEO as separate services with distinct definitions on its own site
- Operating since 2009 and reports serving 200 or more brands
- Delivery is split between US and India offices, so it is worth confirming who staffs the account
- Runs a large network of city-specific SEO landing pages, which can make its local footprint look broader than its actual offices
First Page Sage
First Page Sage describes itself as an SEO and GEO agency that grows businesses by understanding their brand, audience and goals, working primarily through thought leadership content marketing campaigns. Its own pages state the firm is based in the Bay Area, with industry-specific practices for fintech, SaaS, cybersecurity, financial services and manufacturing.
The homepage states directly that it is an SEO and GEO agency, and the site carries a dedicated generative engine optimization service page along with published GEO case studies.
You are a B2B company that wants SEO and GEO driven by thought leadership content rather than high volume publishing.
- Names GEO as a core service alongside SEO on the homepage rather than as an add-on
- Publishes GEO case studies and vertical-specific pages for fintech, SaaS, cybersecurity and manufacturing
- Its own site states the firm is Bay Area based
- Does not publish a street address or an explicit founding year on its site, only a Bay Area location
- Covers answer engine work mainly through blog and research content rather than a standalone service page
Boomcycle Digital Marketing
Boomcycle Digital Marketing is a Bay Area agency founded in 2003 with offices in San Ramon and Pleasanton, California. It offers SEO, local SEO and Google Maps ranking, Google Ads management, web design, video production and social media management, aimed largely at local service businesses.
Its about page lists two verifiable East Bay addresses and states the firm has operated since 2003. That makes it one of the longest running genuinely Bay Area based SEO shops on this list.
You are a Bay Area local service business that needs Google Maps and local SEO rather than AI search work.
- Two verifiable Bay Area office addresses, in San Ramon and Pleasanton
- Operating since 2003, the longest tenure of any agency on this list
- Clear specialisation in local SEO and Google Maps ranking
- Lists no GEO, AEO or AI search optimization service, so it is traditional SEO only
- Based in the East Bay rather than San Francisco proper, and oriented to local service businesses

Why work with a SEO agency in San Francisco
San Francisco has the most search-only agencies of any US city in this directory. Two below do organic search and nothing else, which means depth rather than a general digital menu.
It is also the most expensive market here. One agency lists a 50,000 dollar minimum and 300 dollar hourly rate, so budget expectations should be set early.
Published minimums run from 5,000 dollars to 50,000 dollars per project. Several Bay Area agencies publish no pricing at all.
