Selling private ads can come in the form of banners, buttons, or links. You can even make money writing sponsored posts where you write about or give a review of an advertiser’s product or service. Another option is to write an underwritten post or series, which is where you can write about any topic, but the advertiser pays for a “Brought to you by” mention in the content.
Have in-depth knowledge in your niche? Package it up into an ebook and sell it on your blog. I'd generally advise against selling it (at least exclusively) on Amazon or Kobo, as you'll probably be able to charge much less. If you've already built up a solid audience, you can probably change anywhere from $5 for a very short one, all the way up to $39+.
Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
