Local mobile advertising opens a new world of possibilities for brick-and-mortar businesses, both big and small. The ability to send relevant information to people at the exact moment they need it is something marketers have always dreamed of, and it's now a reality.

Geotargeting on mobile allows you to refine your ad reach to serve only the most relevant audiences at those key moments before a purchase. The granular targeting capabilities of Google's display ads allow you to get a robust return on investment from your ad spend, even with a limited budget.

It might mean fewer impressions and even clicks at first, but, when done right, it can significantly increase conversions.
