Ok so i'm trying to rank a site high just using white hat. It's the first time ever im trying white hat LOL... since like 3 years! But its going good tbh! So i checked out my a site ranking on page 1 for the keyword i want. and they have a few links on "slide share" (Google it cause i cant post links) it ends in .net I have never heard of the site before but its page rank 8 on its home page. I haven't check if its do follow yet. But you can upload pdf's. I just made a picture in paint then converted it to a PDF... then uploaded it. Was just some text about my website. I entered a description with my link... the links in the uploads description you can't hyperlink. But if you go to your profile they have a section where you can upload the link. Im going to test it and see if it gets any traffic for my site. However there is some files with 1000+ views. If anybody knows of any other sites like this could you please let me know. I wouldn't say this is a file sharing site but its a kinda youtube for pictures? Free backlink on an authority site at the end of the day! And no.. its not my site I WISH... nor am i promoting it or anything.
