Do you want to add a Google map to your WordPress site? There is an article at wpbeginner.com called How to Add Google Maps in WordPress.

The article says: “Go to Google Maps website, and simply type in the address of the location you want to show or search for a location. Once you have found the location, click on the link button in the right hand panel. This will show you the embed code. Copy the iframe code or you can also click on the “Customize and preview the embedded map” to further customize the appearance of the map on your site”.

Another way to do this is to use the plugin Shortcodes Ultimate.
