Facebook Audience Network was recently expanded to include support for mobile web; now making it possible for Facebook advertisers to extend the scale of their Facebook campaigns beyond Facebook, mobile apps and into mobile websites.
What this simply means is that if you advertise on Facebook, you can make your ads to display on Facebook, in mobile apps and on the mobile view of blogs.
For you to advertise on Facebook Audience Network, you must enable "Mobile News Feed" placement and the ad type must be one of the types below :
==> mobile app install ads,
==> mobile app engagement ads,
==> website conversion ads and
==> website click ads.
If you’re already running mobile News Feed campaigns, all new campaigns will automatically be opted-in to the Audience Network. You don’t need to upload new creative (your ad's images and text). Ads in the Audience Network use the same images and text as Facebook ads that run in News Feed.
Keep in mind that the Audience Network is designed to extend Facebook ad campaigns and can't be purchased by themselves. So, you cannot enable your ad to run ONLY on Audience Network for now. You must opt in for "Mobile News Feed". What this simply means is that if you advertise on Facebook, you can make your ads to display on Facebook, in mobile apps and on the mobile view of blogs.

You can add a call-to-action button to your creative. The mobile ad will show the specific call to action that you chose while creating your ad. For example, if you selected "Play Now" when creating your ad, the button on the Audience Network will also say "Play Now".
If no call-to-action button is selected, install ads will default to "Install Now" and engagement ads will default "Open Link". The link ad will also keep the same call to action that you chose when creating the ad. If no call to action is selected, it'll default to Open Link.
I hope this helps.
