Microsites are ideal solutions for promotional purposes. Microsites are small, self-contained clusters of information, differing from large websites by the cohesiveness of information they provide.
The idea behind microsites is to create a lightweight system of networking a few pages with information that is tightly concentrated for best effect.
They have to be flawlessly functional, but focused on the aesthetics and the content served. Rather than covering a broad range of topics larger websites tend to, microsites are limited to conciseness and information transfer, which makes them an excellent promotional tool for all serious businesses.
