Facebook has officially launched the Audience Network: The power of Facebook ads, off Facebook. That’s what you see here, in this image, a Facebook ad on Shazam. It uses the same targeting you find on Facebook including Custom Audiences, core audiences and lookalike audience. And you can use the same measurement tools to see if the ad is working for you or not.
When Facebook first announced the network, back in April, it was for app installs and engagement only. Now, the network handles link ads, so pretty much anything you can run through Google, you can now run through Facebook.
