I started thinking about this the last night and thought I would throw this out here to get other people’s opinion. Could too many comments devalue your post in the eyes of Google? Think about it for a second. Google’s Webmaster Guidelines clearly states "Keep the links on a given page to a reasonable number (fewer than 100)." But you will often see post containing many links to external resources or examples. In addition, every comment contains a link to the person’s profile page. On top of all of that, many people will add links inside of their comments. Would Google actually penalize a blog post for being so popular? My guess is that they are smarter than that.
Anytime I try to determine the positive (or negative) SEO value, I always like to weigh the facts. So below are some facts that support both cases. There are actually some compelling cases for both sides.
Making a Case that Google Does Not Penalize Popular Blogs with Comments Containing More Than 100 links
Google loves Blogs, and popular blogs get lots of comments and links. You would think Google is smart enough to account for this in their algorithm.
Most comments link to other pages inside of ActiveRain and not to external pages.
The comment links contain nofollow tags thus telling search engines not to pass on juice to those links (and thus saving the juice for the "real" links?)
ARDELL’s blog post with 250 comments shows up on page one for the search phrase "bait and switch link"
Making a Case that Google Does Penalize Popular Blogs With Comments Containing More Than 100 links
The Google Guidelines clearly says that pages should not contain more than 100 links.
Google is not just counting external links. We know this because Google’s guidelines says, "If the site map is larger than 100 or so links, you may want to break the site map into separate pages."
Could ARDELL’s post be even higher in Google if she didn’t have as many comments?
What Do You think?
I would like your opinion, and especially the other SEO geeks out there. Has anyone seen any sites that address this? Does Google ding you for too many comments? Should Blogs implement a paging system for comments to avoid this?
