Since then that site has been rebuilt three more times, with the most recent version beginning only a few months ago.

I'm building an affiliate network marketing business.
In the meantime, I've switched my book links to Amazon and made a considerable heap of money from online work. It is my main income source. I've tried other affiliate marketing programs with limited success on various sites.
I believe it is dangerous to put all your eggs in one basket - so I do get income from other sources - but affiliate marketing continues to challenge me. It helps that I like to write articles.
It takes time and focus to build a career in affiliate network marketing. Essentially it means putting links to products on your blog, such as the book image I've included with this article.
Not only does a blogger have to write great articles to go with their affiliate links, the blogger needs to have a strategy for attracting people to their blog. That is most effectively done with good keyword research, effective writing, and search engine optimization... which essentially means, doing everything Google and Bing like, and avoiding what they don't like.
You could do what I did and learn from trial and error over the course of many years, or you could get guidance from experts like the bloggers at Pajama Affiliates, where they offer informative and effective online courses and affiliate network marketing opportunities. If you're not sure you want to pay for a full class, try out their $1 fast-pass sampler of some of their video tutorials.
This is my first article for the 2016 A to Z challenge. I chose to use this blog because here, I can write short articles without feeling pressured to write more. On some of my other blogs I prefer to write at length, but I can't commit to doing that daily for the A to Z challenge.
My articles will all be focused on my affiliate marketing career. I hope bloggers will find them helpful.
