Google Autocomplete – go to google.com, start typing a phrase and look at the dropdown autocomplete results. You can use the underscore character “_” to have Google fill-in-the-blank. Just make sure the last character you type is an underscore. Try using plurals and change the word ordering to see different results. This is how I find 90% of my keywords.
Affiliate Marketplaces – ShareASale and ClickBank have thousands of merchants to choose from. It’s nice to login to 1 place and check the performance of multiple affiliates without going to each individual portal on each website. Many programs aren’t part of a marketplace though. I’m a big fan of ShareASale – there are so many companies and industries you can choose from.
Once you have the affiliate links you need, it is time to present them to your audience. As you start using affiliate marketing to talk about products, you need to be aware of how your audience perceives you. If your website appears to be only after their money through an overwhelming amount of affiliate links, then they are more likely to simply leave your site.
