Yes, that is explained on our Facebook Advertising page.
Facebook ads are very different to Google Ads. Google's ads, especially the ones in search are unique. They get your product or service in front of potential customers when they're looking for you. Facebook ads is less active, it is more like traditional ads on the television or radio - they're interrupting people's day with an ad offering something they didn't know they wanted. There are excellent opportunities there, but it is a very different beast from Google's Search Ads.
