A microsite, also known as minisite or weblet, is like a supplementary paper you receive with your news paper on and off. Technically, it is either one or cluster of pages which are meant to function as a supporting document to a parent website. They are meant to add a specialized segment for information or commercial value. It can either be a permanent feature or added for a particular event. The contrast between a microsite and its parent site is its reason and explicit cohesiveness. Commercial value of microsites is what makes it particularly worthy for many businesses. Other than providing product specific information, they can also lower your pay-per-click cost as it focuses on particular keywords to improve your quality score.
