Sitelink Extensions: third-party links
Do you know if it's allowed to make sitelink extensions with destination urls different to main ad url (not to social media)? Ex. we have an ad with destination url www.aaaa.com/bbb and want to make an sitelink extension "Booking" with url www.dddd.com (it's a landing page for booking request and currently we can't move it to main site).
Re: Sitelink Extensions: third-party links
It's an interesting question.
If I go by the policy (https://support.google.com/adwordspolicy/answer/1054210?hl=en) it says that:
"Third-party links: In limited circumstances, sitelinks may point to third-party sites such as your Google+ page, Facebook page, Twitter, YouTube, or LinkedIn. If doing so, the link text must be descriptive of what someone would find on that landing page. For example, "Watch our video on YouTube" should lead to your video on YouTube."
Did you try implementing the sitelink going to 3rd party link which is actually your Booking platform for the users?
