Overall it’s a pretty simple widget. You enter your zip code, radius for search, gas type and sort order. You are then provided with “up-to-date” (as claimed by the widget creators) gas price list for your area and the locations. The widget has the usual links back to the parent site and Clearspring powered sharing tools.
One simple feature that we felt was overlooked is a “Map It” feature. On each of the listings a “Map It” button could link the user to a Google Maps powered page on Automotive.com. This could easily drive more traffic to the site and that map/directions page could be monetized. Leveraging Google Maps or even any other mapping system would be dead simple.
