Instead of creating multiple variations of a page, you might want to direct visitors to different destination URLs. Learn how to do that.
In general, page variations are meant to increase your page's relevance. However, in some cases, it might be easier to achieve relevance by directing visitors to entirely different pages.
To keep it hands-on, let's imagine we're creating a Facebook post for Music.ly. Normally, we'd connect our post to a landing page like this, where the user has to select their matching app store.
Pick a web page (in our case: musical.ly). Next, click on "NEW PERSONALIZATION" and check the box "redirect to a different URL". Here you can insert the link that you would like to redirect to. Repeat the process if necessary (e.g. to create a redirect for the Apple Store).
Now, we have to define who should be redirected to the Google Play Store instead of seeing our original page. To keep it simple, let's say we want everyone who access our page through an Android phone, to be redirected to the Play Store.
We defined our audience as "operating system equals Android".
