Another targeting mistake is by language. On Facebbok, My profile includes Swedish, Italian and Dutch as languages I know. I've seen ads in those languages even though the products aren't even close to available for me (Though the ads are kinda memorable, especially the Postnord ad that I ran into for about 100 times, I wonder how much ad money they spent solely on me)
