How to provide coupon code for Liking my website?

Hello,

I'd like to offer my visitors a coupon for liking my website. However, I'm not sure how to implement this.

For example, I want to make sure that the "like" is successful before sharing a coupon code with the visitor.

Does anyone have experience implementing such a thing? If so, what's the best way to do this?

Thanks in advance for any help,
Bruce

The coupon is always the same or it change everytime?

If is always the same it's an easy thing to do (i mean for fanpages, of course), a little more difficult if you are talking about a website.

Thanks for the reply.

Yes, it would be the same coupon code.

And, it would be for a website, NOT a fanpage.

Any helpful tips on how to do this?

Thanks

you can add a content locking system, they can only view the content once they liked your site.
