FACEBOOK ADVERTISING SERVICES
Reach Facebook Fans More Efficiently & Effectively
As mentioned, Facebook allows you to target its user base to a very granular level, which is something traditional ad platforms do not offer. You get more than just rough readership / viewership numbers and can slice and dice the audience as you need to.
How much and how often you want to spend on Facebook advertising is also up to you. One of the reasons Facebook advertising is so cost-effective is that you can choose to use the pay-per-click model (similar to Google AdWords) whereby you only get charged when someone clicks on your advertisement.
