No one wants to do things hundreds of times. If there's a way you can automate something, you should. This applies when you're uploading thousands of products as well as when you have a ton of affiliate links. If you recommend multiple affiliate links on one site, you can use a pattern-matching technology called regular expressions to create affiliate links on-the-fly. This way, you don't have to create a cloaked link for every single product.

It also makes it very easy to manage affiliate links. Sometimes, affiliate links change due to a change on the vendor's side. When that happens, if you use a regular expression, you only have to change the link in one place. If you have hundreds of affiliate links, you'll have to change each one manually.
