assume you have a blog post... domain.com/blogid/titleand then you have 500 comments on that post.your blog page shows your post and 10 comments, and then you page comments using ajax. I was thinking about having a link on the blog page with something like view all comments and its url would like domain.com/comments/blogid so that users with javascript turned off and googlebot and read all comments by visiting that page. but obviously, first 10 comments would be duplicated, and how does googlebot link the comments back to the original blog post? Basically, how should I do ajax paging so that it's SEO (googlebot) friendly
ajax paging - duplicate content - seo
seo;search engines
That won't be an issue. Some of the content is duplicate but not enough of it is to be considered duplicate content. If it were enough then every ecommerce store that sold the same product and used the manufacturers description would be considered duplicate content and only the first to publish it would be in the SERPs. That would be insane.If you want to display all of the comments for a page and have it associated to a post, have a link that displays all of the comments and the blog post as well. Use rel=canonical on the version of the page you want to show in the SERPs.
