The AdSense blog has announced the launch of a new feature called “Site Authentication”.
The Site Authentication feature give AdSense crawler access to your password protected pages by passing it information to log into your site. All you need to do is provide AdSense with a username and password. Then the AdSense crawler will gain access to those protected pages and be able to serve up relevant ads based on the content.
For example, let's say your news site has a premium content area, with articles that only paying members can access. To get ads on those pages, you can use Site Authentication to provide our crawler with a test username and password. It's an easy process that starts just by logging into your AdSense account and finding the 'Site Authentication' link under the 'AdSense Setup' tab. Once you've supplied us with a username, password, and a few other details, all you have to do is verify that you own the site through Google Sitemaps.
Note: You will only have access to this feature if you've updated your AdSense login to a Google Account. If you don't see the Site Authentication feature in your account, it is likely because you haven't transitioned your AdSense login to a Google Account. If this is the case, please update your login.
The Google AdSense help section describes how to set it up:
To create authentication parameters for your pages, follow the steps below. Most of the steps require you to take action using the Sitemaps and Webmaster resources provided below:Google, AdSense, New Feature, AdSense Features, Site Authentication, AdSense News
- Create an authentication rule by accessing the Site Authentication feature in your account, located under the AdSense Setup tab.
- Log into Sitemaps using your Google Account. You must be using your Google Account in order for any changes you make in Sitemaps to be reflected in your AdSense account.
- Add a site to your account by following these instructions.
- After you've followed the instructions, on the next page, choose the Verify your site link under the >> Next step section. If you can't find it, then go back to the Sitemaps homepage and then follow these directions. - To learn about the two specific types of verification, see verify using META or verify using HTML. - To learn more about verification in general, see the Webmaster Help Center.
