While I’m searching all the index page of my blog http://latest-seo-news-updates.blogspot.com I found that Google cached one of my blog page http://latest-seo-news-updates.blogspot.com/2013/06/basic-and-advanced-seo-techniques-to-generate-traffic-to-your-website.html as well as http://latest-seo-news-updates.blogspot.com/2013/06/basic-and-advanced-seo-techniques-to-generate-traffic-to-your-website.html?showComment=1372054729698 These two pages are showing while I searched site:http://latest-seo-news-updates.blogspot.com I’m so afraid about it because these two pages are same with same content. Does google consider these two pages as duplicate? If so what can I do now? Is it really a big problem to my blog? I need clear answer about it..
Make sure that Google is not able to index the URLs of blog comments, though Google knows that those are blog comment URLs, chances are certainly there that they may be considered as duplicates. Use ajax and have a comment's URL structure like this (with '#') http://moz.com/blog/how-should-mark...-results-have-dramatic-changes#comment-230107
