Paolo,
I'm not exactly sure what you're trying for.. if you could let me know which of the below sounds most right, I'll tell you how (if it's possible) to do it:
* You want a Like button on your website that shows the count (or allows user's to Like) your Facebook Page (
www.facebook.com/AnnabSeteDautore)
* You want a Like button or counter on your Facebook Page which shows the count of Like's on your website (not really possible, just so you know).
* You want to get an email notification when a user Like's your Page or your website?
For reference, the Like button is specific to every URL. So, your website doesn't really have a 'total' count of Like's for it. There's a Like count for your home page and each sub-page, but no 'total' count. You can see a total count for your Facebook Page because that's just one page in Facebook's eyes.
Hope that helps get you started, but let us know a bit more about your goals and we'll help how we can!
Alex
