I've tried using Slideshare and Scribd for traffic. Uploaded documents, ranked them on the first pages, gave good descriptions but any good traffic won't show up. When I put a document or slideshow on Slideshare I usually get between 200-250 views the very first day, from the next day only 5, in a week the traffic disappears. On Scribd I can only get 5 hits per day for a week or so. The shock is this traffic doesn't convert and they don't even leave comments. I don't publish poor content or something. I see most people have the same problem with these sites meanwhile there are big guys who indulge themselves with huge traffic and popularity. Do you succeed with document sharing sites? How do you do it? Please, share your experience.
