Become a better and smarter SEO

Rank Theory is a twice-weekly newsletter containing emerging theories, illuminating experiments, and occasional shitposting.

Sean is one of the few people I keep in touch with privately about all things SEO. There aren’t as many people obsessed about staying on top of what’s working as him.

Hello! Sean Markey, here. I’ve previously spent time as director of an SEO agency before leaving to build and grow my own niche sites. From 2019 to 2021 I built and sold several websites for multiple six-figure exits. These days I love reading about SEO, experimenting, and writing about SEO. I live in Vermont; it’s amazing.
