What worked the best for us is to use literally anything else besides Google Ads.

Seriously, it's akin to lighting money (and time) on fire, and you'll only get dragged in further over time, requiring more changes, more time, more monitoring, more updates, more you.

Save your sanity and go with something less "black-boxy" and more in your control. Yes, it's more work upfront, but it's worth it in the long run.

Google Ads is not working for your best interests.
