A microsite belongs to a specific website, but is moved to a separate domain for content reasons. The microsite focuses on a product or service and can comprise one or more pages. Due to the special focus, the products or services are shown to better advantage than on the main page and can therefore be presented to the target group in more detail. The design can be individually adapted to the respective online campaign and is not necessarily bound to the corporate design of the homepage. microsites are particularly suitable as SEO tools for improving search engine rankings.
