Unlike most offline marketing efforts, digital marketing allows marketers to see accurate results in real time. If you've ever put an advert in a newspaper, you'll know how difficult it is to estimate how many people actually flipped to that page and paid attention to your ad. There's no surefire way to know if that ad was responsible for any sales at all.
The mobile device is a uniquely personal medium that has transformed the customer journey. The pervasiveness and proximity of mobile makes it a powerful tool for marketers to understand and anticipate customer behavior. As a result, marketers now have the opportunity to respond to their users’ needs, goals, feelings, and expectations with a customized experience — both in and out of their mobile apps.

I’ve been giving out some form of this advice for the last two years, so I figured it would make sense to organize it and provide it here, for anyone motivated enough to follow it.
