Adwords: Optimizing for Mobile
Website Magazine has discussed mobile website design in the past, but we have not really dug in on optimizing mobile advertising campaigns - perhaps because until recently there was no such opportunity. Or at least no viable opportunity in mobile advertising.
A tip in a Google Adwords Support thread however addressed some best practices for advertisers looking to capitalize on the 400 million mobile internet users worldwide through Adwords.
The tips address campaign structure and bidding, keywords and ad text specifically, but Mobile Business Pages from Google are also addressed which makes for some interesting reading, especially if you don't want to take the time or resources required to develop an entirely separate mobile Web presence.
