is everyone missing the actual question that was asked ? which was, does allowing users to post comments benefit SEO ? (no mention of whether links are follow or not and yes i know links TO your site from do follow blogs are beneficial) but in regards to the actual question allowing users to comment on your website should actually benefit SEO due to the unique content that will be added providing the content is not from an automated source. so be sure to have spam protection and also disallow links being injected in comments from users.
yes its a most important bcz some blog sites are not catch in google. so plz gives comment thanks.....................
with smo you should actively participate in the same activities that your audience does, with seo is no much participation..
I'm also sat that Comments on dofollow blogs are good for SEO. It is useful to get google ranking. ..
Its good for backlinks but its bad for SEO purpose. Imagine a blogpost having 300+ comments and 90% linking to nasty sites, and your site gets a link from the same page~ I personally hate blog comments.
dofollow is goood but be aware if Google Caught you doing it they will remove your whole site pages and anything related to it so BeCarefull
