If you want contact someone running a Facebook Page, you can head over to that profile or rely on post comments. Now, the social network allows you to send messages directly to those businesses as soon as you see an ad.Page owners can opt for an ad's call to action to be a Send Message button that would allow you, a prospective customer, to contact them directly for more information. The feature also lets businesses and page admins respond directly (read: privately) to any comments left on a page. When they do, a note will appear in the thread letting other visitors know they're in contact.
Pages will also get a badge in their profile based on response time. To earn a "very responsive to messages" badge, the page will have to respond to 90 percent of messages and have an average response time of under five minutes. And yes, you can toggle your personal settings so that businesses and other pages aren't able to contact you directly if you wish. There are plenty of tools for admins too, including saving commonly-used responses to lower that reaction time. The new messaging feature is available today, so you're sure to see it pop up in Facebook ads soon enough.
