Masked domain forwarding — available only to Yahoo! Domains and Business Email customers — allows you to redirect your domain name to another web site, while concealing the web address of the destination web site. Your visitors will see the original domain name in their web browser's address field, and the destination site will appear within a frame.

Because of this frame, search engines cannot pick up keywords in the page to which you've forwarded your visitors. To ensure that search engines see these keywords, you can enter them after selecting the masked forward option.
