This question doesn’t make sense. As blogging alone doesn’t make anything, you have to monetize it first. There are a number of ways to monetize a blog including, AdSense, direct advertising, affiliate marketing, and much more.
For example, affiliate marketing would be a way to monetize the blog, rather than blogging and affiliate marketing being two separate things.
Which way are you currently monetizing the blog? I feel affiliate marketing is a good earner if you have engaged traffic. Whereas if you have a lot of traffic but not much engagement google AdSense maybe the better route. As Google can pay out per impression or click.
