Hi Ignacio - in order to use your own domain name with your published Unbounce page for your Adwords campaigns, you will want to add the domain as a custom domain into your Unbounce account.

There are a couple of steps that are required, starting with creating a CNAME record with your hosting provider, as well as adding the custom domain into your Unbounce account itself.

To review all the steps required for this setup, please see: http://support.unbounce.com/entries/2…

If you have any questions about the process or experience issues, please don’t hesitate to reach out to the Success team at support@unbounce.com
