Domains and Affiliate Marketing

Most affiliate marketers are no stranger to the domain name market. At the very least, they probably have a domain name for their website or blog. And some have dozens of domains in their possession.
There are a few ways that domains can be used in affiliate marketing. Many affiliates create niche sites or blogs for the sole purpose of promoting affiliate programs. Some also purchase domains to redirect to their affiliate links. This makes the URL shorter, easier to remember and more appealing.
If you're serious about affiliate marketing, you'll probably end up with several domains. But it is possible to go overboard with them. Some affiliates feel the need to buy a domain for every affiliate program they join. Not only is that expensive, it can also get extremely confusing.
Even if you are buying domains to redirect to your affiliate links, you don't necessarily have to buy one for each and every program. If you belong to several programs in the same niche, you could use a general domain name and create sub domains for each program. For example, if your niche is herb gardening, you might be an affiliate for a seed company and the author of a book on herb gardening. But instead of buying a domain for each program, you could get a domain like herbgardening.com and create the sub domains seeds.herbgardening.com and book.herbgardening.com to redirect to your affiliate links.
It's also possible to be too conservative when it comes to buying domains. In general, it's best to have a domain for each niche you're in. And in some cases, you might find that you need two or three for the same niche. There are no hard and fast rules. Just do what's most comfortable (or most profitable) for you.
