no follow link from edu can gov help for SERP or not? a lot of IM say that is very useful for your web or blog link with them, but isn't helpful for SERP? if they link to your web or blog?
edu or gov links dont worth anymore than com or net links. besides, google doesnt count nofollow links also so no benefit for google. in terms of other search engines like yahoo or bing, they do count nofollow links so if you find some good links, grab them
