I had good experience with twitter and facebook (if it is a B2C product) in the past. Press release is also important, but in the past most of related big internet sites ignored our press releases - I think you need to figure out who (responsibly person) to send your pr (e.g. at techcrunch, heise, TR etc...) to be not ignored. If you have a physical product a good way to promote it is to send it to related bloggers and internet sites to test your product.

Thanks for the advice. It is an advertising network to help website owners sell directly to advertisers. I doubt techcrunch an other big pr sites would want to cover us. I was thinking of a paid pr release.
