The Google Politics and Elections Blog made the announcement last week. Previously campaigns could target via zip code. Now, they've added the maps for all 435 Congressional Districts.
Now, with congressional district targeting in AdWords, campaigns can quickly and easily target their search, display, mobile and video ads *solely* within that particular district’s border. You can start by heading into AdWords and selecting your District number from the location menu populated with district information in simple Google Maps format, prepared by Azavea. Build your ad and you’re on your way.
We’ve built a sizeable team that is working around the clock to help all candidates get the most from their online advertising efforts. Congressional District Targeting in AdWords is just one more way that we’re working hard to deliver better ads for users and voters and better tools for political campaigns.
