In December Google launched their ad network for Android and iPhone, which allowed advertisers to target AdWords at mobile devices with full HTML browser capabilities. They now have a short video available explaining the differences between what they call standard and high-end mobile ads, the kinds of sites to which they may be linked and how you should choose between them. If you aren’t using mobile ads yet, now is the time to start your learning curve because they’re only going to become more ubiquitous over time.
