Hello Friends, I am seeking kind help from the experts on SEO. In my blog, I find that three urls are being generated for a single article as on date. Out of these three urls one is a SEO friendly url containing the title of the article. Whereas other two are dynamic urls (For example sitename.com/articalDetails?qry=6308) based upon the article ID like 6308 stored in the database. Can any one guide me as to whether these three urls can cause problem in Google ranking in SEO? & whether Google will treat it as a duplicate content? Recently one guy suggested me to to replace the old dynamic urls with SEO friendly urls. This being a manual activity is very cumbersome. Should I change the code of the blog so that dynamic urls are not created from now onward. Thus looking for an expert advice please. Best Regards. Yogindernath
