When is a directions link enough?
If you already know the venue, show the address and use a Google Maps URL to open directions to it. Maps URLs do not need a Google API key. The visitor gets the route in Google Maps.
An interactive map inside your page is a separate decision. Use it when people need to compare several venues or see where they are relative to one another.
Which Google Maps Platform actions can create a bill?
The Maps JavaScript API requires billing and credentials. Interactive map loads use the Dynamic Maps billing unit. Place searches and route requests have separate usage rules and free allowances.
List the services a visitor actually uses. A page can load a map, search for a place and compute a route in the same visit. Read the rules for each event before enabling billing. Keep your own venue record separate and check Google’s storage and display rules before keeping Places results.
How can you check what the venue link needs?
Use a fictional venue on paper. Do not open a map link, enable billing or enter real coordinates.
- Write the destinationInclude the venue name and street address. Mark the destination as the only location your page needs to pass for this task.
- Draw two visitor outcomesShow one person reading the address and another choosing directions. Keep the address visible for either person.
