Until now, CPC accounted for all clicks including likes, comments, shares, clicks to a website, clicks on "continue reading," and others. CPC will now account only for clicks related to a given ad objective, like clicks to visit another site, call-to-action clicks that lead elsewhere (like "Shop Now"), or clicks to install an app, for example. Engagement clicks (likes, comments, and shares) will no longer be counted.
