2010
Big Fin SEO was founded in 2010 by Michael Fleischner, a career digital marketer, author, and TEDx speaker with more than two decades of search marketing experience. Michael built Big Fin because agencies were being asked to deliver services they couldn’t staff, and businesses were being sold SEO programs that produced reports but not results.
2015
Tired of spammy SEO tactics, Big Fin focused on what works: quality content, clean technical foundations, and genuine authority building. The team grew and expanded across 40+ industries, earning a reputation for doing the work that actually moves rankings.
2019
The client base grew as Big Fin guided companies through every major algorithm shift with clarity and consistency. The agency partnership model began taking shape, giving marketing agencies access to a dedicated fulfillment team under their brand.
2023
We automated the management of Google Business Profiles with the GBP app called, “Big Fin Local” to help hundreds of small businesses automate local optimization and improve their online visibility.
2024
As AI-powered search accelerated, Big Fin invested heavily in Generative Engine Optimization methodology. We began building the frameworks, tools, and processes that would power our agency partner GEO program before most agencies knew GEO was a category.
Today
Big Fin’s primary mission is to help marketing agencies grow by giving them a world-class GEO and SEO team they can call their own. We are the team behind the GEO results your agency’s clients need, delivered under your brand, at margins that make business sense.

When you go to the beach, what do you love to do?

The people, hands down. Our crew is smart, supportive, and genuinely fun to work with and the same goes for our clients. Big Fin SEO is the kind of place where collaboration, flexibility, and good vibes come naturally. It makes every day feel purposeful (and just a little bit fun, too).
When you go to the beach, what do you love to do?
The beach is my favorite place; it energizes me. When I go, I love to lay in my favorite chair and watch the ocean while my daughter builds sand castles at my feet. Then as a family, we walk the shore to collect shells.
