Domain name investors spend a lot of time researching WHOIS information to see if a domain name is available or to contact the owner to make a purchase offer.
I’ve created two simple bookmarklets that allow you to quickly check WHOIS information for a domain name. To save these bookmarklets, simply right-click the links below and bookmark them, or drag the links to your bookmarks toolbar.
The first scenario is that you visit a domain name and see a developed website, and you want to see who owns it. Just click this bookmarket while on the site and it will open DomainTool WHOIS in a new tab with the domain already filled out:
The second scenario is that you are reading an article and you see a string of text that you want to check availability/WHOIS on. Just highlight the string of text and click this second bookmarklet, it will remove any spaces or punctuation, append “.com” to it, and pop up a new tab for DomainTools WHOIS with the domain already filled out:
If you find this useful or have any questions let me know in the comments. Enjoy!
