Cool but they need better coverage of the internet. Looks like they are only scraping some sites. I couldn't find any sites in my niche. Top alexa sites only? ¯\_(ツ)_/¯
We crawl 200+ million websites :) Click the "Deep Web" button under the search box on the homepage.
Thanks for the tip but I tried the "Deep Web" option and still can't find any of the sites. They are small sites that get about 100-500 visitors per month. Also, there are a lot more than 200+ million websites on the web.
