The content of a company's overall strategy broadens as their web presence grows and they acquire more information to include throughout their website.  Creating microsites is one way to avoid becoming too broad in your offerings. A microsite website differs from its parent site in that it tends to focus on a single topic.

However, Microsites can cover a variety of topics, including an upcoming event, a profitable product, or a seasonal product.  Microsites can be a simple and effective way to draw additional attention to these things.
