Why directories are the best passive income side project
Directories have three properties that make them ideal for passive income: organic search traffic compounds over time, paid listings create recurring revenue, and the catalog grows itself through user submissions. Unlike blogs that need constant new content, a directory's value grows with every listing added.
- SEO traffic compounds: every new listing is a new indexable page
- Recurring revenue: monthly/yearly paid listing subscriptions
- Self-growing catalog: visitors submit their own listings
- Low maintenance: automated moderation, Sheets sync, AI enrichment
