What Your Competition is Doing Next
Using a WHOIS information service can give you tons of information. In fact, using one is how I was able to dig up all those Google registered domain names.
Using a domain explorer, such as the Whois.sc Domain Explorer I was able to quickly find hundreds of domains with “Google” in them. Then it was a matter of looking for the common registrar mentioned in the article.
Using this tool one can look at and around their competitors sites to see if there are possibly other domains out there waiting to be set up. This tool will tell you registered domains, as well as those that are actively hosting a site or just parked.
