You can add a website to be linked from the Title of the Marker Bubble. This is very useful for supplemental data, such as a website with more information about a location. To include the link, include the full web address, called a URL, as an additional column in your spreadsheet. This can be a web page that you control or another, such as an official website or visitor review page. Just make sure it’s the full URL, including http:// or https:// at the beginning.
The URL field under Advanced Options defaults to a Google Maps link, but you can make it any page on the Internet. Select the name of the column where you have the web URL in your spreadsheet and it will appear one of two places: if you have a title selected, it will now be clickable; otherwise, the link will display at the bottom of the Marker Box.
The method above creates a clickable, "Active Web Link. If you just want the Website URL listed in your data and not active, then do not select the URL field and list the web address without the http:// at the beginning.
