For anyone serious about building a business with affiliate marketing, I would recommend running multiple sites on a variety of topics.
Traditional shopping and buying patterns are fairly predictable, and online business transactions follow similar models. People search online for things that they are interested in right now. That means that near Christmas they may look for gift ideas, or in spring they may start thinking about home renovations or bbq supplies.
So what does this mean for the affiliater marketer? It means that you need to anticipate what will be popular in the future. If you are looking for new ideas for a site, try and think of what will be “in season” 6-8 months from now. This gives you time to research your keywords with WordTracker, register your domain and launch your site.
Having a variety of sites on various niche topics will help smooth out your revenue stream for the long term.
