Big Fin SEO builds AI visibility for businesses across ChatGPT, Google AI Overviews, Gemini, Claude, and Perplexity. We are the white-label GEO team behind some of the most respected agencies in the country, and we work directly with select clients who want access to that same expertise.
For Agencies: Big Fin is the white-label GEO fulfillment partner for marketing agencies. We deliver AI visibility services fully branded as your own, at margins between 50% and 135%. Your clients see your brand. You collect the revenue. We handle all strategy, execution, and reporting.
For Businesses: We occasionally work directly with businesses that want access to the same GEO methodology we build for agency clients. Direct engagements are selective. If your agency doesn’t offer GEO and you found this page, you are looking at the team most agencies quietly rely on.
Our GEO program is built around 12 core pillars of AI visibility, covering the technical, content, authority, and measurement layers that determine how businesses are cited in AI-generated answers.
Every engagement starts with a GEO Readiness Audit that maps your current AI visibility across all major platforms, identifies gaps, and sets a prioritized roadmap for improvement.
Choose the tier that fits your clients’ goals and budget. All tiers are month-to-month, fully white-labeled, and can be upgraded as clients grow. Direct client engagements are scoped individually.
GEO is new enough that a lot of agencies and vendors are offering it based on theory, not experience. Big Fin has been building AI visibility programs since the category was still being defined. We combine 15 years of technical SEO rigor, deep experience across 40+ industries, and a proprietary methodology that spans all 12 pillars of AI visibility.
Real-world testing in ChatGPT, Gemini, Perplexity, and Google AI Overviews. White-label delivery infrastructure built for agency scale. GEO work that holds up, delivers measurable results, and represents your agency or business with the quality it deserves.
Not sure where your clients stand on AI visibility? Our GEO Readiness Audit identifies gaps across all major AI platforms and delivers a prioritized action plan. It is the fastest way to scope a new GEO engagement and show clients exactly what they are missing.

GEO stands for Generative Engine Optimization. It is the practice of optimizing your digital presence so that AI platforms like ChatGPT, Gemini, Perplexity, and Google AI Overviews cite and recommend your business in their generated answers.
SEO focuses on ranking in traditional search results. GEO focuses on how AI systems understand and recommend your business. The disciplines overlap significantly, but GEO requires additional work around structured data, entity signals, content formatting, and AI-specific optimization.
The GEO Readiness Audit identifies your current AI visibility across all major platforms, maps the gaps in your technical setup and content, and delivers a prioritized roadmap for improvement. It is the starting point for every new GEO engagement.
