Hi Have some questions on backlinks and duplicate content: 1) Which social bookmark site has strongest backlink - Digg, stumbleupn or squidoo ? 2) If you post in digg.com and your post gets only 1 Digg, will it show as backlink in Google? Or do only posts that get it to homepage of digg.com get backlink in Google? 3) Would posting same article in 100 Social bookmarking or 100 blog network sites or 100 article sites be considered as duplicate content? If it is duplicate content, does that mean Google would only show 1 or 2 backlinks ? Thanks
