I need to know about something. I've looked on our Wordpress website and notice that there are hundreds of "comments" that have been made on the website. Obviously these people do this to do SEO of their own. But they are all trash to me. The question is, can I delete all of the comments that have been made on the website? There are some images that was allowing people to comment I guess. But Wordpress shows you all of them and I think there's like 6,000 comments. If I delete all of these comments, is that going to affect my SEO? I need to know, it's pretty important.
It is going to affect your SEO if those blog comments are dofollow. If they are nofollow blog comments you need not worry about your SEO rankings. Perhaps, you can start focusing building quality links rather than worrying about these blog comments.
you can also delete spam comments automatically or protect your wordpress website by using wordpress comment plugins.
