Read "How to Make Money Blogging" by Bob Lotich for $5-$10 on Amazon.

Use his trick of...

1) Run Google Ads on blog posts for 30 days.

2) Start with highest traffic page + move down.

3) Visit the page + hit refresh 10x time, recording the Ad showing up.

4) Then replace your Ad Units on this page, changing Google Ads to the actual site originating the Ad Unit identified in #3.

You'll do this by visiting the site + signing up for the site's affiliate program, so you drive traffic from your site to the Ad site directly, without Google as the Middle Man.

5) You may be very surprised about revenue you can generate with this model.

6) Start with this first, then move on to working on your courses.
