I added coop ad code to several pages more on my page and I still get sam weight after recalculation.. shouldnt it be raised?
It sounds like you only added coop to some pages, the coop weight is based on the pages indexed in google, adding the code to pages does not affect your weight, however adding new pages and increasing your PR does affect the weight. In saying all of that, as per the TOS for the coop the code must be added to all pages on the domain/folder that you have signup up with.
