Web apps showing MLS with SimplyRETS geocoding addon

The Geocoding Addon will give every listing in your feed a latitude and longitude. This makes building map-based search pages easier and faster without any performance hits to your site. If your MLS's data already provides lat/lng, you will not need this addon, but most do not.
