Where does the code go?

In your site head, or a Google Tag Manager tag.

Do I have to edit every number?

Wrap each one in your class, or set the class to * to swap them all. The * class doesn't work for URL-based DNI.

How many numbers do I need?

Source and URL types use one number per source or tagged link. Session pools start at one; Support sizes them.

Will I see which ad click called?

Yes. The GCLID and search words are saved with the call.
