Tip: Aim for products with reasonable commission. No lower than let’s say 40 percent, to make your efforts worthwhile. Also, you should note that ClickBank deducts transaction fees from a sale. Here’s a calculator to help you calculate your actual commission. More so, you need to remember to disclose all your affiliate links and mark them as nofollow. Here are a few reasons as to why you need to do this.
On one hand, long and ugly affiliate tracking links are a straight giveaway to people that you want to sell them a product (and people may be uncomfortable clicking on them). Therefore, making your link shorter and "nicer" looking will it give a more professional appearance. One of my favorite plugins for making links look "pretty" is the Pretty Links WordPress plugin.
If you have built up an email list, you could also promote your affiliate offers via email promotions. Just make sure you build up a relationship with your audience first instead of going for the hard sell straightaway. The emails you send out must contain your affiliate links to products so when your audience click through. the sale is attributed to you. 
Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
What this article teaches you is that if you produce something that is shareable and interesting, driving traffic to it is MUCH easier. You can use social media, you can run link building, you can share it on niche communities and nobody is going to ban it or downvote it. Actually, if your front end is great value, people will share it around without you asking. Then all you have to do is offer a free downloadable resource in this piece of content (that does not decrease its shareability as it's more free goodies) and THEN start selling via email follow up.
I, too, have always looked at ClickBank as a secondary and even tertiary monetization source. But it can be a great sources of revenue. I linked one of my articles to a related product on CB, and without really doing promotion or anything unusual, I get a few sales a week. Mind you, the keyword(s) for the post aren't that huge either. So, even though the traffic not huge on that post, it still manages to get some sales.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
