Google Maps plugin features an option, which allows you to group objects situated not far away from each other into clusters. This option will come in handy when you have to set lots of markers. Thus you can help your potential customers locate your business headquarters and affiliates in less than no time. Zooming in on the area, in which the marked objects are located, will result in a more detailed view and put markers further apart. Besides, you can set the plugin to distinguish markers by categories, so that a particular type of marker will refer to a certain business group, so that users can distinguish between affiliates belonging to certain business networks.
