I want a link on my site which visitors can use to get directions to my location. Is it possible to create a link to a Google Maps directions page, where one end of the directions (the destination) is pre-filled?
Set the origin (Place A) as "current location" and the destination (Place B) as your desired address. Then save that link.
Grab the link (icon next to the printer icon) and you can use that hyperlink.
Whenever someone clicks on that link it will start from where they are located, no matter where that is, and show directions to your designated location.
