Email is a relationship-builder with your potential customers. You want to send them a balance of useful information related to your niche, perhaps an email newsletter, as well as marketing messages, like a sales email, asking them to buy a product on sale. The free information you’ve provided helps them come to know, like, and trust you… which makes it more likely they’ll buy a product.
One huge red flag is any company that promises you a “get rich quick” marketing strategy. Although affiliate marketing can be good money, it’s by no means instantaneous. Stay away from anything that sounds too good to be true. Also, stay away from any merchant that wants to charge you startup costs. Additionally, use established affiliate programs to find your merchants. Read reviews and ask around. You’re not the only person trying to supplement income with this marketing strategy, so there are plenty of other professionals with whom to crowdsource.
Conversion is a targeted action performed by user after a click on the ad. The "Conversions" column in AdWords helps you evaluate the effectiveness of different data in a cross-section: an ad campaign, an ad group and each separately, keywords, a search query, the type of traffic (Computers, Mobile devices, Tablet PCs), demographics (age, sex) location, time, etc.
The diverse array of companies involved in email marketing ensures that no one party can make changes that would have a widespread effect, and unlike Facebook or Twitter, if you invest the time and money into building and cultivating a great email list, your subscriber list will be an asset you own. Thus you’ll be able to leverage your list without the threat of someone limiting its effectiveness.
The way SAN operates is pretty similar to other high-ticket membership products like Digital Altitude (that one was shut down by the FTC for fraud), AWOL Academy, Mobe, etc. Overpriced and designed to make as much money as they can from their members. They keep pushing their members to upgrade their memberships and buy the next level/product. At the same time, they tell you that this is the way to earn money online. Making money online has nothing to do with buying levels. It has to do with working hard and offering solutions to your audience problems.
The main difference between referral and affiliate marketing programs is that a referral program is a program where you're structuring it for your customers to refer people they know and an affiliate program is structured for people that have not used your product or service themselves to promote it to people they don't know in exchange for a commission.
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.
Although other affiliate training manuals have some strong points (and I do recommend one as a companion to the Super Affiliate Handbook), most affiliate marketing training manuals currently sold are either seriously out-of-date; fail to teach valuable site and traffic-building techniques (such as blogging) or completely bypass essential marketing methods. Furthermore, one of those that fails to teach the basics is also ridiculously expensive.
