Conversion tracking question

what page does the code go on?

Silly question . ..

Do I need any google conversion tracking code on my landing pages?

Or JUST on the conversion / thank you page?

Just on the conversion/thank you page.

Also you won't see the image show up unless you actually click on your ad, and then buy a product/submit a form to reach the conversion/thank you page.
