Did you check with several tools that no links are getting indexed ? (Google Webmaster Tools, MOZ, Ahrefs, MajesticSEO...).

If your links are not visible on any of these crawlers, they are probably not very valuable anyway.

With owner permission "having your name on the site in unlinked text" seems the best to do.

I remember the penalty story of 'Web Design Yorkshire by Pinpoint Designs' - http://moz.com/blog/ultimate-guide-to-google-penalty-removal

<greyhat>Need to vary anchor text if you do it :).</greyhat>

Forum helps you to collect mails, can be very valuable.

If you want people to register easily, try a Facebook login system + allow a dofollow link on profile. Maybe that the forum just launched by Quicksprout can inspire you.

Would you have enough time to run a blog + a forum ? If you are usually busy, step away from forum and focus on blog.

Thank you for your answer people. It looks like index,nofollow would be indeed better.

By looking more on the net, I also found a yoast article about this issue: http://yoast.com/wordpress-threaded-comments-and-seo/

"WordPress automatically adds a noindex, nofollow robots meta tag to each URL that has ?replytocom in it."

This is why all my comments URL look like http://www.example.com/example-post/?replytocom=1

Yoast plugin update offers an option to remove ?replytocom variable. I think that I will have to drop All in one SEO on this website...

Hi,

I changed the design of one my wordpress website at the beginning of the month. I also added a "facebook seo comments" plugin to rewrite facebook comments as normal comments.

As most of the website comments are facebook comments, I went from 250 noindex/nofollow comments to 950; URL's are ?replytocom=4822 etc.

Moz campaign noticed it and I'm asking myself : is it good to have comments in noindex/nofollow ?

Should I do something about this ?

Erwan.
