Both In-Stream and Discovery are pay-per-view -- you pay YouTube a fixed rate for every view the ad receives -- and their return on investment (ROI) can be measured in Google AdWords. YouTube tallies one new "view" after 30 seconds of watching, or a click on the video as it's playing. If the video is less than 30 seconds, views are tallied from people who watch the entire ad.
Did you ever guess that your obsession with Twitter or Pinterest could become a key employability skill? I know! You first start Pinterest, you think it’ll be a little harmless fun, and then you’ve got hundreds of boards with thousands of pins on DIY projects you’re never going to do and recipes you’re never going to make (sorry, real talk) – but you also understand all the lingo, know who the influencers are, and have an experienced eye for what makes an enticing Pinterest post. Maybe this same story applies, except with Facebook (you know the power of groups and how FB ads work), Twitter (you’re always up on the latest trending hashtags), or Instagram (you follow all the influencers in your niche).
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
