Minimal Advertising Wastage
Facebook allows companies to target their advertisements based on geographical locations, demographics and specific keywords on audiences' Facebook profiles. These options enable advertisers to increase or to restrict their messages by country, state/province, city, age and interests. In other words, it gives you the control to minimize advertising wastage by reaching out to the right people, at the right time and at the right place.
"Facebook Insights" is available to monitor your advertising campaign. Information such as Responder Demographics (including aggregate age, gender and geo-location), Responder Profiles (including audience shared interests) and The Advertising Performance Report (including impressions and click-through rates) are beneficial to identify new targets or eliminate targeted audience, as well as to manage your budget—further optimizes your message.
