How do I reduce my Google Maps API bill?

Count what triggers each call. Address autocomplete often sends a billable request on every keystroke. Wait for a short pause and a few characters, use session tokens so searches can be billed together when a place is chosen, restrict your key to your site and the you use, set daily quotas, and cache only what the provider's terms allow.

Every keystroke sends a request, and without a session token each one is billed on its own.

Common questions

Can I cache Google Maps results in my database?
Only within Google's terms, which restrict most caching. Place IDs may usually be stored; some coordinates only for a limited time. Check the current service terms.
