Friends, there are lots and lots of press release websites. As we know paid sites like PRweb and free sites like free-press-release, prinside etc.. But don't you think that all the sites are not useful?? Many websites won't allow links, some allow links but no keywords. Which one will be helping more for search engine optimization? I think the ones with sites like free-press-release (not even a link to the website) are waste.. What do you think? Feel free to share your knowledge and experience.. Thanks.
