What kind of commission do they offer? One-time commissions or recurring commissions? For example, many programs pay you one time for sending a customer. On the other hand, some programs like membership sites or SaaS (software as a service) programs will pay you a commission as long as the person you referred is a paying customer. Recurring commissions are great when you can find them!

I am absolutely new to the whole online marketing thing. I visited CB in 2012, then, it appeared overwhelming so I put it on the back burner. A week ago I revisited CB and ran two campaigns without a website nor blog . I went to Fiverr and had traffic directed to my CB ad. At this point, I'm just waiting to see if anything converts. I jumped in without knowing too much of what I was doing... I needed to take some type of action.
The final section of the course summarizes everything, explores the issues that might occur and ways to deal with them. Since affiliate marketing is essentially a part of online marketing, it will be helpful to learn how affiliate marketing integrates with search engine marketing, social media marketing, email marketing, etc. These strategies are analyzed from both perspectives, those of merchants and affiliates. Furthermore, the topic of online marketing and its segments is worth exploring more in the future as it can improve your success with affiliate marketing, regardless if you are a merchant or an affiliate.
Always fill out the comment box to “sell” your platform. If you are given the opportunity to explain why you are interested in a program, do it! Use the space to highlight why you would be an asset to the program. Talk about how your audience is their audience. Talk about the size of your mailing list (if it’s significant). Talk about your success with similar programs. Talk about where and how you will promote (hopefully you’ve done a bit of research so you know what they’re hoping for). Don’t sound desperate and certainly don’t lie about anything, but be upfront and honest about how this will be a win for them.
Once your hosting is set up, you need to install a content management system (CMS) for your site. We recommend WordPress because it is easy to use and a beginner (like you!) can quite quickly figure out how it works. Most good hosting providers will have a one-click install option for WordPress, which means it will only take you a couple of minutes and you will have WordPress installed on your site. 
I'm just starting at Clickbank, so I'm a total newbie, but if I want to follow this strategy can I do it promoting just one product, for example, Category>Health & Fitness ---> X product. Then, should i start a blog or something like that where i can talk about things related to the product subject? if so, do i have to start making entries about this recurrently? or I can opt for just making an article with a free ebook in exchange to user's e-mails and follow the process?
Be honest. Talk about what you like and don’t like. Be fair and build trust. It will serve you well later. For examples, check out my review posts about Elite Blog Academy and Self Publishing 101. I get emails frequently from people who tell me they decided to purchase one of those courses through my affiliate link because it was the most balanced review they found.
Take advantage of marketing tools whenever possible. Many affiliate programs offer useful resources to their affiliates aimed at helping affiliates make more sales. These range from monthly newsletters highlighting upcoming sales, tips or affiliate case studies, Facebook Groups just for affiliates, private webinars explaining marketing strategies in depth and more. Ultimate Bundles does this exceptionally well.

My business, Pure Residuals, was developed and launched in July of 2013. It is my primary website, but one of many over the previous 10-15 years of earning real money online. I have made thousands of dollars selling other peoples' stuff for fantastic commissions and I truly enjoy doing it and teaching others how to get started and eventually become a full-time online marketer.

#2 High Priced.  Another downside is that the course does cost more, a lot more.  At $997 it does sound like a lot but I prefer not to look at the cost as a burden but rather an investment in my future.  The way I see it if this teaches me how to how to build even a modest income of a $1000 per month for the rest of my life I feel the price is well worth it.
