    Does PDF submission sites pass any value to seo? Many times i've read in threads like "web 2.0 list" few PDF submission sites and i was always wondering why they are there. I wanted to take advantage and build few of them, but i got so many doubts. Here are few:
    I got chrome add-on that shows all external links of one page but links in the PDF somehow are invisible for this tool. I guess it was some error so i tried with Majestic...my links from PDF sites still did not appear even in majestic.
    So, does google really see those links and how?
    Im talking about sites like: scribd, slideshare etc...tnx a lot guys :)
