A Microsite is one or more pages for your product or service, hosted within the radio stations site. There are two key values a Microsite brings you. First, it's far more than a banner, it's an entire page, or group of pages, dedicated to your business sitting within the radio stations web site, taking advantage of the relationship between the station and it's listeners. Second, your Microsite could affect your Google rankings, not to mention appearing within Google itself.
