Hi I have my adsense for over 2 years now i am starting to use it and is it possible to use same adsense code on multiple website or do I have to create each ad code for each website thanks.
Hello, You can use same ad code to all website. No need to create separate ad code for different sites.
If you are talking about the ability of using the very same code block on several pages, then the answer is : Yes, as long as these pages are owned by you and legally compatible with AdSense "Not a violation to any term" But if you are talking about the effect on your earnings by placing this one code to the entire website, then I'd strongly suggest one AD per page with different styles and positions ...
