I was wondering if links from PDF documents get picked up and accounted for by search engines. Anyone has experience with this?
I'm not sure about this. Google certainly indexes the contents of PDF files. Given that, why would it not also index any URLs within those files? And if it can do that, it should be able to recognize a link as a link. And if it can do that, why would it not count links in a PDF file just as it does links on an HTML page? This is not a statement that the previous posters are wrong - more a question as to what those opinions are based on.
Minstrel may be onto something. G does index them and in fact converts them to html format (you know the option to "view as html". Maybe they count, I dunno.
