How to set up conversion tracking in google ads?

Question

Google Ads

Good afternoon, wt. specialists. Can you please tell me where you can read about setting up conversion tracking from google ads itself? Maybe someone has a site where it is configured exactly like this and it works. Because did everything according to google instructions, created conversions, got the code, marked it up on the site - it doesn't work. Conversion counting fails. Yes, in this case we are talking about onclick. Those. you need to count the conversion on a click.
