As the title suggests, iv heard conflicting views on this... example; you have a website on the finance niche... in theory could you take a handful of articles on this subject from article sites like ezine and articlebase and copy the article and put them on your site? 1) would google see this as duplicate content? 2) is there a limit ? you could create whole blog sites of hundreds of these articles? 3) would these quality articles add value to your sites? or will they be ignored when it comes to serp increases? 4) what applies to news sites? like the bbc, sky etc taking content from their and putting in your blogs?
