If your blog is active and interactive, you are going to frequently find money keywords in blog comments. That means you have a massive opportunity to make more affiliate sales or drive more traffic to some internal pages on your blog.
I’m a blogger who makes money from blogging. I know every section on my blog can be used to ethically generate income. The comment section is not left out.
Once you are getting comments from your readers, you can actually reply to these comments, directing them to a resource on your blog or to an affiliate product. This can be done without manually inputting links in the comment.
