Though the comment display order has not been a big topic of discussion online, the comment section is a very active and attention-grabbing spot on every blog that has it enabled. It’s where bloggers and readers interact the more.
As a matter of fact, some readers spend more time on the comment form than on the post itself. The reason is that they skim through and then scroll to the comment section to drop a comment. Most do that to get a backlink (which is not a good reason to comment)
If you are running a heatmap tool on your blog, one thing you’ll discover is that the comment section on your blog posts (mainly, the comment form) has more clicks.
