Google revises its AdWords platform to improve advertisers' experiences2
Google discovered that increasing preview information increases the number of clickthroughs by 20%. So AdWords will now allow more text to be seen by the viewer before he/she clicks on a link. The 25-character headline will now be 30-characters, and the 30-character headline will be expanded to 80 words.
AdWords, which is based on an auction process where advertisers compete for their ads to show up with searches for certain keywords, is also making a change to the bidding process. Advertisers will be able to make individual bids based on the type of device, mobile or desktop, that their ad appears on. And Google will enhance the images of ads to help them blend into websites that they will appear on.
The average Google search user probably won't notice much of a difference once these new features are implemented over the upcoming months. Advertisers will notice, and they are the ones that pay Google for the ad space.
