I recently made the camp of a product X. Now on my page I have a different products let say X, Y and Z. Now the problem is X is related to Y and Y is related to Z but X is not directly related to Z. I have not seen anything against that in TOS. Do you guys thinks it's oky to leave the page like that or do I need to take product Z out of the page.
I'd gather data related to performance with it on the page, then remove the product and analyze the impact.
Without seeing the ad & page my guess would be no, you're not violating anything in the TOS. If in doubt contact the AdWords team.
