I have AdSense running on my main site www.inmate-connection.com and I have just started a blog located here: http://inmate-connection.com/Wordpress/ Can I copy my AdSense codes from my main site and paste to the WordPress blog? Will I be violating any rules? Please help me. Thanks.
No, there will be no violations to the rules and regulations. You can put the ads to any number of sites without getting them from google.
You can always use adsense on any page you like - but that page or section must be compatible with google adsense terms - there is no need for you to take permission for every section or page you are embedding adsense with hope this helps...
Yes you can add adsense to your blog of main site as well as other pages of main site without any problem. Just take care of below given. How many Google ads can I display per page? DON.
You might want to set up custom and url channels (if not already done, and if all codes are going to be the same) so as to easily track their performance across the two sites; You might need to customize the ads - e.g for colour in your blog - not sure if that can be easily done, if that ad was not created specifically in adsense...
