Can copied post outrank original post??

I agree with what Mr.Radhakrishna said.It all depends on the page rank of the site/blog which is determined by the traffic that site is generating and how smartly the keywords have been used.

Well Manish,

i will say Yes, but the fault is Trackback url has to be mentioned.......because sometime during copying we will left somethings and we will post it in normal way.......because the same thing has happened with me even i use to post the article in Toostep by copying from somewhere but in some article i have mentioned the trackback url and some i forget and same has been tracked by AHMED SULTAN AND DEVI KALADEEN.

and their comments realise me the importance of trackback url..............

so, i can say that with trackback url if somebody is doing this thing then it's good because in actual way they are making aware to others about the knowledge of the thing that u have posted...

but without trackback if somebody is doing this then one should have to make that person realize abt. that as Ahmad And Devi did for me.

thanks to you both and to Manish u also because with ur this question i got opportunity to appolozize for the mistake i have done during my postings

Also if the keywords used by the other blog is much better than yours then his blog will appear on the top....First preference will be the page rank of the blog/ website...

Right if that particualr blog or site has better response then others, so this could happen...

Hello Manish, it is a real problem in the world of digital content. In case with the search engines, everything depends on some mathematical calculations and formula-based assumptions on how the data source or Web-site is popular. Search engines may use different parameters to calculate it, e.g. content replenishment and novelty, how often and regularly it is updated, how many cross-referrences to this site exist, its distance from the center of Web-graph etc. The search engine cannot take into account copyright and content duplication issues, at least so far. It will require from it to be intelligent enough to determine somehow whether the content is original or copied one, use some content authorship protection mechanism or at least to determine somehow who was the first (e.g. by publication data or by querying some content registration database). But now, I can assume that if your site has a lower rank, than other site which copied your content, the search engine will assume that you have copied their content. So, no wonder they copy-pasted content outranked your original one.

Yes, copied posts CAN outrank original posts. The ranking does NOT depend on the quality of the material. It depends on the rank of the publishing source.
In your particular case, we can say that the other blog (or website) has a higher rank than your blog.
