Liked on YouTube: Insights on the AdWords Auction http://youtu.be/PjOHTFRaBWA Hal Varian, Google’s chief economist, provides an in-depth and insightful overview of how the ad auction works. Hal describes how the auction system works so that consumers always see the most relevant ads and advertisers get the most value. He also provides insight into the key components of ad rank: bid, quality and formats, and the way all of this works together to determine your ad’s position and cost.
While it’s pretty basic insight into how the AdWords auction algorithm works, it is well done and perfect for AdWords beginners. There are plenty of more advanced videos, but I like this one because it’s official Google material, so it’s very well polished and authorized by the Goog themselves.
