For many offers the really big opportunities for affiliates lie overseas and Facebook is perhaps the simplest and most accessible way to buy targeted traffic in these markets. Nanigans is a company that provides Facebook ad campaign management and this week they launched a new infographic that draws from 175 billion ads impressions managed by them in 2011.

Note that the size of the square is proportional to Facebook’s reach within the country, so you can get great penetration in the U.S., India, Turkey and Indonesia, for example. The color represents how expensive the CPC rates are for that country, with Sth Africa, Denmark and New Zealand heading the list. Mexico, India and the Philippines look like good value.
