Google this week introduced the ability to target more than 30,000 ZIP codes in AdWords, giving advertisers the ability to find potential customers in a familiar, granular way.  Another new feature, Location Insertion, is aimed at letting advertisers with multiple locations create one ad, and have information dynamically inserted depending on the user’s query or location. Both features are part of location extensions, which are also getting some other tweaks in response to feedback.

For ZIP code targeting, advertisers will be able to add up to 1,000 postal codes at a time. They’ll also be able to view campaign performance stats by ZIP code
