**Programmatic SEO is a scalable way to create relevant web pages that solve customers' problems, leveraging existing data and pre-programmed rules. It's used by businesses like Nomad List, Trip Advisor, and Zapier to drive traffic and increase revenue. Programmatic SEO involves creating database-driven pages that can be easily updated and expanded using no-code tools. The process includes keyword research and content planning, designing a page template, collecting data, building the database, connecting it to the website, testing, and making adjustments as needed. While programmatic SEO isn't suitable for every business and has its challenges, it can be lucrative if executed correctly for the right business.
