Well I was curious about Google's algorithm and when I got the results I asked some questions here to get an idea, what you guys know and I got mixed answers. Firstly I made a website with copied content and not much backlinks - Code: http://motomodders.socialgo.com Its nearly 6 months old and got pr 0! Second site had everything copied but good backlinks - Code: http://www.downloadcity.info (It was adult and now I removed adult stuff, but it was pr 2 with adult content and without those videos) So I came to know that backlinks are important but then I thought it might be some problem in experiment as first site was sub-domain and had a lot of backlinks and it might be like that - google adds up copied articles to pagerank. Then I checked out third site - Code: http://www.motorolafans.info (Its totally changed now and everything of experiment is removed) This site didn't had much backlinks at that time and everything was copied and it was pr 0 and now nothing is copied but less backlinks and I got good visitors but pagerank is 0. Now I am starting to arrange for backlinks and I think it would reach pr 2 in next update. Conclusion - Backlinks are for pagerank. Articles are posted to get in search results and pagerank helps in getting in top of the results. Copied content don't affect much as my site - download city didn't had anything original and got pr 2 but i accept that it didn't used to get much organic traffic. So firstly you need a good pagerank and then some original content and this can do magic! NOW PROVEN!
