Read a number of posts saying that posting the same article to different article directories is not good since google will view it as duplicate content. However i believe apart from some very reputed sites, most of them will accept the article if it is ok and not spammy...and we will be getting backlinks from them. For example if i manage to submit a single article to say around 25-50 article directories and it gets accepted in all the sites...that would mean around 50 backlinks for my site...i understand the part of it being duplicate content but i will be getting backlinks from all those directories..do the search engines disregard the backlinks in such a situation?
