I have i think interesting question for everybody here who using adsense. How to block my website posts url's to not appear on Facebook at all. I ask that because Social media today is not good for adsense,and everybody can post a link of one of my posts from my website on Facebook. How must look my post url to can't be posted on FB? Thanks
You can't stop anyone posting a link, but you can lookup the referrer when traffic comes to you and block or redirect any coming from specific domains (such as facebook.com)
it really depends what platform your site is build on. Yes I believe you can use an htaccess file, but i haven't done it, i just code it in my php code to check the referring link
