Ok this may seem like a silly question, but I started using the allowed sites under adsense the other day. I typed my main page, greenmowers.org into it. I was wondering if adsense clicks would still make me $ on my other pages, such as http://www.greenmowers.org/what-is-a-green-mower.html The adsense help said that it would work for all sub domains, but never said all pages. Thanks.
Yes. All you need is the domain name. So any page (as well as www.greenmowers.org for example) is included. Read the examples on Google's site. It says.... Example URLs example.com allows all pages across all subdomains sports.example.com allows only pages across the 'sports' subdomain
Allowed site feature is domain based. So when you added a domain everything under it will be allowed. I haven't checked but I think this will work same for sub domains too, same way.
That's not a subdomain. It sounds like that you might be new to the whole website business. What you mentioned seems to be nothing more than just another webpage off your main site. All pages within your site that you paste adsense code into will be accepted (as long as they don't openly break google adsense rules).
