While rates vary by demo, here’s a high level look at costs for targeting specific consumers on facebook.

Group of Eight: If you look at the G-8, Facebook users in the United Kingdom are the most expensive to reach, while Italian and Japanese users are the cheapest

Emerging markets: With lower costs of living and smaller numbers of Facebook users, these countries naturally have lower suggested bid ranges. China, which has largely blocked Facebook access, has an estimated user base of just 34,000, so its range is probably not very reliable. Brazil and India also are the remaining strongholds for Google’s Orkut social network and Facebook hasn’t made deep in-roads in either country. That being said, Russia leads BRIC countries in CPC and CPK levels

Age: Older users are more expensive to reach than younger users

Employers: Amusingly, Facebook employees are much more expensive to reach than employees of other companies like Google or Goldman Sachs Group Inc

Media brands: Facebook users that are interested in or like CNBC are more expensive to reach than users who like other media brands (presumably, they work in finance or have significant investable or discretionary income)

Legacy approach to marketing: Ask for the sale. Ask for the sale. Ask for the sale. Convert.

Web 2.0 approach to marketing: Educate. Syndicate. Reinforce. Convert.

• Educate — Think of content as a welcoming mat – it transcends websites, social networks and formats. Content connects consumers to you, and it’s all the more effective when it’s viral
• Syndicate — Using platforms like Tubemogul, dlvr.it and ShareThis will help manage the syndication and dissemination of content across the Web
• Reinforce — Remarketing techniques that present your offers as potential customers travel to other websites help reinforce an online marketing campaign. Once the seed’s been planted, keep watering, remarket and make the sale bloom
• Convert — make it rain. enough said.
