When using Yahoo's location targeting, how can you implement a radius around multiple zip codes simultaneously to reach a specific local audience?

To implement a radius around multiple zip codes simultaneously using Yahoo's location targeting, you must individually add each zip code as a target location and specify the desired radius for each. While there isn't a direct bulk upload feature for defining a single radius encompassing multiple zip codes, the effect can be achieved by defining each zip code's radius separately. For example, if you want to target a 5-mile radius around zip codes 90210, 90001, and 90404, you would add each of these zip codes as individual target locations within the Gemini platform. For each zip code, you would then specify a 5-mile radius. This approach essentially creates overlapping circles, each with a 5-mile radius, centered on each of the specified zip codes. Users within any of these overlapping areas will be targeted. Keep in mind that overlapping the radiuses will cause an increased density of impressions within those areas. It is also possible to target using DMA (Designated Market Areas) or regions for broader geographic targeting, but using multiple zip codes with a radius is most precise for a targeted local audience. Ensure that your bid strategy and budget account for the potential overlap in audience reach when using multiple zip codes with defined radiuses.
