Stock Photos Used
Hibu doesn't do good business. They use stock photos that are all over the web. This will give your site a ranking hit because the content isn't original. It's all over the web.
Domain Name Length
The way they choose domain names result in them being too long in some cases. Hardly anyone would ever be able to simply type in your domain name with out mistyping it.
From what we know they charge for an upgrade for the video they produce. It's basically the same video with different images and voiceovers. Some people do use their own videos.
Design and Branding
The web designs are basically the same across all niches. Plus they brand your site with their links. One click and your customers leave your page. It's bad enough they put their footer on every site.
