What is cost per reach?
When talking about Facebook Ads, cost per reach (CPR) calculates the relationship between the amount of money you have spent on advertising costs versus the number of people it reached to determine the price for every 1,000 people came. It is a Facebook bid strategy option and tells the platform how much money they can bid in the ad auction. It guides the average spend that platform will target throughout the campaign.
For the company advertising, the measure gives an insightful overview of the effectiveness of your digital marketing strategy for Facebook advertising. It shows if your ad budget is doing enough to drive traffic. The CPR metric can show you if the audience you are looking to target is expensive to reach if you are in a saturated market and if your ad messaging resonates with the suitable viewers to create brand awareness.
