         Document sharing sites are sites that allow you to upload documents,including PDF files,Word Docs;PowerPoint slides,open office documents,and so on.Another benefit of these sites it that these sites normally allow you to write a description of your document.So just like article marketing,you include a live link back to your site and gain a precious back-link.
