I think it depends if you’re doing Direct Response Ads, or branding. With DR if your sales / leads are not generating a Return on Adspend (ROAS), you will change or stop advertising. With branding, you might not even notice that Google is sending traffic from the wrong country. And you might be happy with the great looking vanity metrics. My experience with Google (YouTube) Ads is that they work extremely well. I use them to generate leads for solar panel installers.
