I know much of any response is going to be conjecture, but do you think being listed, or featured in Google News boosts your site's pagerank at all?
Then answer is no. The listing just help you in traffics aspect but has nothing to do with seo, in both PageRank and Ranking.
I don't think there are an obvious relationship between Google news lists and the PR of your site. But I am sure that if your site has been listed in the Google news, you will gain as much as free traffic there.
i think dear it is right because google new pages index with in 15 min so if we put link of site it will also index.
I think the news there gets lost after a certain time. If not PR it sure could get some good traffic.
Do you mean to say if the site has been listed with good SERPS then it will have a good PR too? I don't think it is possible.
