hi all, i have a website that contains google adsense , my question is : in another website (not mine) that have google adsense too , my website is integrated on it (not by Iframe but with php technic), so my question is this legal or not ? thx for help
Well, I think as long as both of your adsense codes do not appear on the same page at the same time, it will be OK.
If you do not want your Website to be used in that manner, definitely contact that site's owner, and ask them to stop. It is illegal for them to do that if you have not given permission.
Displaying AdSense from 2 different accounts on the same page is actually allowed (well, it isn't forbidden but it's definitely not recommended). As long as you don't exceed the following limits per page: A maximum of: 3 ad units 2 AdSense for Search boxes 1 Link unit 4 different product referral buttons
