At the time I posted that article, a couple of years ago, I was not very experienced with HubPages and hadn't read all through the forums, etc., so I did not realize that most articles with Amazon links like this were not usually featured. And I had not signed up to be paid for my work on here. So I really was just posting articles to share info. If I recall correctly, I originally posted that guide book with a LINK rather than the Amazon capsule. So then, after it was posted and featured, I believe I went back into it and used the Amazon capsule. Sorry, I don't remember the details better. In my latest article--"Camping in Hawaii?"--I used an Amazon capsule, and the editors contacted me and suggested I change it to a link, which I did. The article was soon featured, and I signed up for earnings and Amazon ads. So it's been kind of trial and error for me!
