If you’re doing SEO, you’re probably doing link building, and if you’re doing link building, you might be doing guest blogging as a tactic. Despite Google saying that it’s done as a tactic a while back, I think it’s still a good, viable strategy – if you’re doing it properly, of course.
When it comes to comments sections, the issue with guest blogging is that you’re relying on someone else to manage and administrate the comments for you. On your own blog, you may choose not to have comments on blog posts at all, but if you do, you’ll probably check them and approve/deny them before they go live – and even so, you’d probably get a notification if a new comment is pending.
