Are the discussions in disqus visible to google?
With the recent Google Update (Penguin 4.0), it occurred to us that continuous, active discussion in our blog posts (engagement) are very important, if we are to rank or maintain our rankings.
Fresh content, and active discussions are the ones that matter now.
Now, with all the commenting systems available, the only one that I am sure getting noticed by Google are the comments done via Wordpress, where you login with your Gravatar. Facebook comments are invisible to Google. (Please correct me if I am wrong with this belief)
But, as I browse big news sites, those sites that are heated with arguments among visitors, I noticed most of the discussions are done by logging in with Disqus, a commenting plugin the requires you log in first with major social networks before you can give your comment.
The problem with a blog using only Wordpress commenting is, there are people who don't have Gravatars and accounts with Wordpress, so oftentimes, even if they want to leave their comments, they can't. Having Disqus as an alternative seems great.
So, my question is, to cater to people who don't have wordpress accounts, in SEO point of view, is it okay to use Disqus?
Though, I have some hesitations using these alternative commenting systems, as I have observed in the past that, the moment you make these alternatives available, the wordpress commenting system is getting ignored (which obviously is the one visible to Google).
Can anyone enlighten me on these?
