Sejda

An online PDF editor that handles everyday document tasks — editing, merging, splitting, compressing, and converting files directly in the browser without requiring software installation. Built as a bootstrapped business with no outside funding, the platform grew entirely through SEO by systematically targeting the long tail of PDF-related search queries. Each specific use case became its own optimized landing page, compounding organic traffic over time. The approach now drives 31 million visits per month, with monetization coming from premium subscriptions for users who exceed the free tier's usage limits.
