Customers can now send feedback directly to Facebook about their experiences with businesses. The system is being introduced due to frustrations customers have after purchasing things from Facebook advertisers. A short one-tap survey will be available after a user completes a purchase that was initiated through a Facebook ad. Users can rate their experience with a sad face, a neutral face, or a happy face. A questionnaire will then appear so the user can provide more information. Feedback will be shared with businesses only if they receive a large volume of negative feedback. Facebook will give the business a chance to improve before taking further action. Get the full story at Search Engine Journal and Facebook
