Facebook is a social networking website established at facebook.com.

Information:

Facebook is one of the largest social networking websites that exist, with 750+ million dynamic users since July 2011. Advertisers now focus more on Facebook after the increase in the size and engagement of its audience.

Advertisers may influence individuals through direct Facebook promotions or non-advertising platforms (social media advertising and/or content advertising). Advertising on Facebook is just like advertising done on regular social network sites and has a lower CTR (Click-through Rate). Though, if ads remain CPC (Cost Per Click), meaning the payments rely on clicks, CTR is not associated with ROI.

Favorably, Facebook offers some great targeting options like location, language, likes and interests, connections, demographics, and advanced demographics. The more effective the targeting options, the better the possibility to examine and advance.
