Yahoo Puts Ads in PDF Files
YPN has announced a partnership with Adobe that will allow publishers to put ads in PDF files.
Publishers will be able to upload PDFs to Yahoo, and the ads will be inserted. Publishers can than email the PDFs or put them on websites. The ads will be contextual and will be displayed to the right of the content.
This is an interesting new way to display. E-Book authors have often released free e-books with affiliate links in the as a way to make money, but this allows one more monetization option. One problem I see with the ads is they are not integrated into the content area of the PDFs, so I think the Click-through-rates will be terrible.
If you are interested, you can apply for the beta. It doesn’t look like you have to have a current YPN account to apply, but like the YPN beta, only US publishers will be accepted.
