Before acquiring or hand registering a domain name, I usually do some research on the term in Google. I want to see how many results there are, how many advertisers there are, and whether companies use the term in domain names associated with the product.
When doing my search, I have the Google auto-fill menu enabled, and Google provides a useful list of related searches as I am typing. I sometimes use the results that show up in order to get domain registration ideas. For example, when typing in USB, I get the following options: USB Hub, USB Flash Drive, USB Cable, USB Wireless Adaptor…etc.
Oftentimes, the results are peripheral products that I didn’t knew existed, and sometimes the .com domain of the phrase/term is available to register. When Google first started using the auto fill feature, I had it turned off. However, I’ve since turned it back on and used it to mine domain names.
