You can easily put Google directions link, or a Google map in WordPress sidebar. Some people want to create minimal compact websites with contact information and location in the sidebar of their website. This can be done by inserting the Google Map embed code snippet into a standard text widget. For those of you want a more automated process try using the WordPress plugin Map Press.
MapPress allows you to more easily control Google direction and map embedding on your WordPress website.
