Does it have any sense to have a link to comments for each post in a list (e.g. category page)? If so, does it have any impact on SEO?
Here's an example of a posts list page snippet:
<span> <a href="author_name.html">Author name</a> <a href="2012-03-03.html">Date published</a> <a href="some_category.html">Some category</a> <a href="...">Comments</a></i></span> <p>The excerpt ...</p>
I'm guessing that it would be better not to use the links to comments because they're making Google to index "comments" as a relevant keyword in my site.
