Approximately, how many times must a person see ads before buying?

[Tay-shaun Randall]

I'm a music producer and I use Facebook ads and pay 0.50 for 1000 impression with daily budget 2.00 a day. I also use Google adwords with 0.50 PPC. I target rappers and singers etc on facebook and put beats for sale on Google. Which one is more better and how many time must consumer see ad before clicking and most likely buying?

No way to answer. People are different.

I have seen different numbers cited: 7 in one case, another suggested 5-9 exposures for a customer to recognize and trust a brand, these numbers were for traditional advertisements.

I have to believe the return diminishes in each additional exposure.

In particular you have to change up your facebook ads, particularly the images to avoid ad fatigue.
