Targeting Facebook fans in tier 1 countries such as United States, United Kingdon, Canada and Australia can bring in some decent cash for publishers using Adsense, Media.net etc, since these countries pay out more for adverts. In the meanwhile, those fans on Facebook are very expensive as well. I have noticed that Facebook fans from Tier 2 and Tier 3 countries are more engaging. Maybe that's because Facebook filters them out to the organic reach, since most Facebook advertisers (the top dogs) are already targeting the Tier 1 countries mostly. Tier 1 countries acquire higher RPM rates, which usually result in higher income (even with lower traffic). That said, Tier 2 and Tier 3 countries acquire low RPM rates for publishers, which usually result in more traffic (more resources) with less income for publishers. Example: Tier 1 countries traffic: $5 per 1000 impression with 20K traffic daily: 5 x 20 = $100 Tier 2/3 countries traffic: $1 per 1000 impression with 20K traffic daily: 1 x 20 = $20 Obviously, targeting Facebook fans from tier 1 countries are better in general, especially for advertisement. While tier 2/3 are good for engagement and reach on facebook but not so good for publishers. Many big Facebook pages are filled with fans from tier 2 countries (See screenshots below) Examples of Tier 2 countries include: Mexico, Brazil, India, Indonesia, Philippines, Turkey etc What do you all think about this? Am I on the right track with the information? Could there be an operational implementation to benefit from targeting fans from both tier 1 and tier 2 countries; for instance, goal one; target for publishers(tier 1) and goal two; target for higher Facebook page engagement/reach (tier2/3)?
