In Sitebuilder, you can insert a link to a specific map location by using 'Link options' > 'Map link' in the page editor.

After clicking 'Map link', begin typing the name of your desired location and suggestions will appear below the search field.

Click a location name to insert a [map] tag onto your page. When you click publish, the [map] tag will appear as a link.

When someone clicks the link, the location will display in a map popup with an option to view the location on a full size map.
