Hi, Its like where you can create any page to have information about your site and you get back link too from this post.
Look at Squidoo and Hubpages as mini Blog entries. Be sure to add links to your sites in them for the backlinks. Also do keyword research before you write them. They will rank high in the serps, so choose a keyword that is not saturated. Be sure to add pictures and videos as well.
squido links and Hub pages both are good place to share your site info and and popularize your site get backlink also
The beauty of squidoo and hubpages is that there is no limit as to how many lenses or hubs you can build so you can just build one page after another one and use these 2 sites for unlimited backlink source.
