Hey Guys,
I'm playing around with exact vs non-exact age ranges and their impacts on bid prices. We all know that FB claims to give a discount for clicks that come from "broad" age ranges, but does anyone know exactly how this is calculated?
I stumbled across a demo where I had roughly 100,000 users in mind, but I found that I could target those same 100,000 users by narrowing my broad age range to the center and catching the rest on the outside of the broad range. Let's assume that I want to reach people age 25-35, but instead of paying full price on that entire group with an exact age range, I instead broadly target 29-31 and get the 25-28 and 32-33 sets at a discount.
Does this idea work?
I'd imagine you get only a small % of your impressions from outside the precise range and you have a lower priority with respect to ad delivery, since you're paying less.
That being said it could work well if you had high CTR ads and the peripheral ranges had generally higher click costs. If the peripheral demo had lower click costs the 'discount' might be based on your bid and CPCs in the precise range, thus you might not gain anything over advertising to that demo directly.
