Be sure to take advantage of the .CO Coupon SUPERCO from GoDaddy for $7.49 .CO domains which are regularly $30. That is the first year price and the deal is only available until this Saturday 2/12 now extended until Friday 2/18 !. Imagine if someone typed in your .COM domain name and forgot the ?M?. Where would they go? Hopefully to your site, but only if you own the .CO domain. If you obtain .CO domains to match your .COM you can simply redirect the traffic to your domain. Of course you do not need matching extensions but it is not a bad idea. You can also put any site you want at the .CO domain just as you would any other website.
