: Ajax paging - duplicate content - seo assume you have a blog post... domain.com/blogid/title and then you have 500 comments on that post. your blog page shows your post and 10 comments, and

Alternatively, you could load all of the comments into the post and simply reveal the additional comments through an on-demand 'more' functionality.

I don't think AJAX is the issue here. The AJAX part of it would simply not be visible to search engines. It's the non-AJAX comment link that is the issue.

I suspect if you have 500 comments, then it won't be an issue since there's relatively little duplicate content. However, if you only have 11-15 comments, then the majority of the comments page will be duplicate content, and that could be an issue.

I'm not sure there's a way around this aside from putting a canonical tag pointing to the original page. But this would mean that only the first 10 comments are indexed and searchable. I suppose you could select which 10 comments to display on the original page so that the best comments are indexed, but this still seems suboptimal.

So in terms of SEO there really isn't a good solution for this problem. Most blogs with paginated comments just live with the duplicate content. You could cluster the comments so that each comment page is at least 50% different from the other pages, but this would result in the number of comments on each page becoming unpredictable, which is poor for usability.

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.
