WordPress is an amazing platform for developing any kind of website. One of the first times that became evident to me was when I was contracted to develop the Dealer Locator plugin.
The Dealer Locator allows blog administrators to easily add information about retail locations that would cater to their site visitors. The plugin includes alphabetical sorting and filtering functionality, zip code search, and a set of template tags to be used on the front end for search results. In addition, I developed a custom import facility that allowed my client to populate the WordPress install with over 1600 dealers in her niche. When the plugin is deactivated, it automatically exports all the dealers in the system to a CSV file for use on any site.
