The OverBlog service is completely free.
We handle the hosting of your site and your content. We back everything up on secure, latest-generation servers. In other words, we take really good care of your data. And we're constantly developing new features and options to keep up with any changes to the web and social media.
It won't cost you a dime. You deal with your site. And that's it.
How can we provide such a great service for free? By offering users the option to share revenues by placing ads on their sites.
