How are comments ranked?
Much like Google searches, Google will use a complex algorithm to determine which comments show up first. The website owner always has the option to post a comment that will appear at the top of the list. After that, factors like the credibility of both the post and person making the comment will determine the order of comments. Users can also vote on the usefulness of a post, which Google wil then take into account when ranking comments.
