Let's say my domain name is icecream.com. Now I want to sell a line of candy bars on this site too by running ads on Google and Yahoo but would prefer to use a more fitting domain name like candybars.com instead of icecream.com. So I buy the domain name candybars.com and have it forwarded (301 redirect) to the icecream.com/candybarpage. Is there a problem with doing this? Will Google allow this on Adwords? Can I also mask the domain or would the search engines penalize that? Is there a better way of doing this? Thanks!
