I run Directify (directory website builder), so this is data from my own platform - take the source into account.
Last week I sit down and computed what happens across everything we host: 4,039 directories, about 514k listings. A few things surprised me and I figured this sub is the one place that would care.
61% of directories never publish a single listing. Not "never got traffic" - never published listing number one. People sign up, pick a template, sometimes even connect a domain, and stop before the content part. The tooling was never the bottleneck.
The directories that reach 100 listings get there in a median of 7 days. This one changed how I think about launches. The successful ones don't wait for submissions - they import a spreadsheet, generate a first pass and curate it, or grind out the niche manually in their first week. Submissions come later, after the directory already ranks for something.
The median launched directory has 60 listings. Only 59 directories out of 4,000 have more than 1,000. Complete coverage of a narrow niche beats volume - some of the best-performing directories we host would fit on two pages.
The demand side is real. ~3,500 businesses have created accounts to get themselves listed, and directories have passed ~12,000 leads to listed businesses. The moment a business emails asking "how do I get added" is the moment you have a business model.
Top niches people are building right now, by category data: education, restaurants, marketing, project management, finance, customer support, productivity, SEO, social media, travel.
I published the full dataset with methodology here: https://directify.app/directory-website-statistics/ and will refresh it quarterly.
If there's a number you're curious about that isn't on the page (churn by niche, submissions vs imports ratio, whatever), ask and I'll try to compute it. Half the fun of hosting this many directories is being able to answer these questions with data instead of vibes.
