Yahoo has introduced a number of new geo targeting options to Yahoo Search Marketing, it’s advertising service for the Yahoo search, according to a post on the Yahoo! Search Marketing Blog. Previously targeting United States based users was limited to targeting the whole United States along with Canada, individual states, or Nielson Media Research’s Designated Marketing Areas (DMAs). Yahoo has now introduced the option to target by ZIP code, city, or the United States and Canada individually. Yahoo provides a dynamic map and a search feature to assist in finding the correct ZIP codes for the ZIP code targeting option, which is currently a beta feature.
