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+.
What is CPC? CPC stands for “cost per click.” By displaying CPC ads with Google Adsense, you receive a set fee every time an ad on your website is clicked by a visitor. The cost per click is set by the advertiser. (This is in contrast to CPM ads, where you’re paid for ad views instead of clicks. CPM means “cost per thousand impressions,” where M is the roman numeral for 1,000.)
Post your article links on social media and blog directories. Get traffic to your site with frequent updates on Twitter, Facebook, and other social media sites. Find blogging communities that match your readership and post links to relevant articles on their comments or forums. This helps in getting traffic to your site as well as raising your search engine rankings.
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
