Which you think is the better way? It seems like fanpage allows you to communicate with your Likers yet the other one cannot.
You can add a like button on your website AND create a group around that website in facebook. That works, who likes your website will be added to your group and you will be able to comunicate with them
with a like button you can get people to like your fan page and then from your fan page you can communicate with them. Hope that helps.
Your Thread is not clear. If you want to get facebook like button for your website you can get it from here developers.facebook.com/docs/reference/plugins/like
