I am using Facebook Audience Network(MobileWeb-beta) for ads on my mobile site. But the 320x50 html source code doesn't display the add across the width of the mobile screen as it should, it displays a smaller ad(as shown in the image).
I am using the code given on Fb site:
<div class="fb-ad" data-placementid="xxxxxx-xxxxxx" data-format="320x50" data-testmode="true">
</div>
Any suggestions? Thanks!
Do you have your viewport set? Adding this to your <head> should fix it.
