Currently advertising costs on Facebook are plummeting and the audience is skyrocketing as people all of a sudden find they have more time on their sleeves and are hungry for information. So now is a great time to build some brand awareness but I would be very cautious of the amount you spend if you aren’t able to convert during this time as consumers have very short memories. Also, I would keep a close eye on your frequency (the amount of times the same person sees your ad) you don’t want to be paying for the same person to see your ad over and over again.
