Adobe's Target platform allows users to target audiences based on their geographical location. The geo-location parameters available for targeting include country, state/province, city, zip/postal code, latitude, longitude, DMA (Designated Market Area), and mobile carrier. However, there is no specific mention of targeting by census tract. Since census tracts are smaller, more specific geographic units than some of the listed parameters (like city or zip code), it's unclear if Adobe Target directly supports this level of granularity. For definitive information, direct consultation with Adobe or a detailed review of their latest targeting capabilities would be necessary.
