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.
When you join an Affiliate program and choose the products that you want to sell, sellers provide you with a unique affiliate code that you can use to refer traffic to the target site. Most affiliate programs will offer ready made text links, banners and other forms of creative copies whereby you only have to copy the code and place it on your website to start referring traffic. When interested visitors click on these links from your site they get redirected to the product site and if they purchase a product or subscribe to a service you as the referrer make a commission.
Great stuff here Sean – thanks for all of these insights and sharing some best practices when it comes to affiliate marketing. I’ve never been comfortable giving it a shot, but after reading this post and your perspective on how and when to do it, I may just have to give it a try. Especially considering I’m already mentioning and recommending services and products on my site, I’m just not getting the potential rewards associated with doing so. Thanks again.
