I like that they have real people in charge of their content, rather than just algorithms or bots! They're easy to work through for me because it's super transparent about how much money we make from them (which helps keep us honest). There are some things you can't do if your site isn’t optimized well enough - so be sure there is room/space available before signing up :) We've had good success building our relationship over time at this point without having any other advertising sources aside form Google Adsense which has been great but not as consistent since being integrated into rank siderer last year.
