Understand the different sales models. The most common forms of paid channel advertising are cost-per-mille (CPM) and cost-per-click (CPC). CPM ads are the banners you see across the tops of webpages. You are billed a flat rate based on the number of times the ad is displayed. CPC ads are the paid advertising results you see on a Google search results page or in the side margin on a Facebook page. You pay for every click on your ad.
The peer-to-peer concept is coming to virtually every corner of human existence. That includes the hospitality industry. Through AirBnB you can actually rent out your house for various lengths of time for a predetermined fee. That gives you an extra income on your house and gives the visitor the benefit of having an entire house, rather than being crammed into a single hotel room.
