I have a site/blog in a particular niche and my original intent was to only allow comments that has anything to do with my niche. So far I got some spam comments with some links to some other sites that has less to do with the subject on my blog.
So at first I was thinking of not allowing this comments. BUT, out of a SEO perspective, could it be a good Idea to allow all sorts of comments. I mean it's a great thing when the search engines discovers new content right?
So could also I benefit from allowing all kinds of comments? Becasue I guess they benefit from it when getting backlinks to their sites.
Could it be a good idea to allow all comments without having to approve them first?
