Apparently this is one of the more popular topics on Google Adsense so I chose to write a very brief article on Yahoo Domain names.

Yahoo domain names are inexpensive (as low as $19.95 and $9.95 a yr) and are readily available. You can visit this site to order a domain name for personal or business use:

Domain names consist of www.whateveryouwantyourdomainnametobe.com, you could buy a domain name to advertise and even direct people to your hubs.

Yahoo not only sells domain names, but business e mail, web hosting, marketing tools and also offers merchant solutions and job recruiting services. 

For domain names yahoo offers 24-hour service, domain formatting, a starter web page, DNS management, domain registration, and locking. If you buy a full website your domain name and business e mail are free of charge. You also get unlimited data transfer, storage, and e mail transfer.
