Google launched Site Authentication feature for Adsense user

Let's imagine that you're the AdSense Crawler. You're bouncing along all over the Internet, visiting publishers' sites, and letting the AdSense system back at Google know what the pages are all about. Then one day, you run into a site that asks you for a login and password. "Huh? I don't have a username and password to this site. How am I going to crawl the pages behind that login?"

The result is that your users end up with poorly targeted ads and the AdSense Crawler ends up with sleepless nights, wondering what could have been -- if only it had crawled those pages.

Google recently launched a new feature called Site Authentication to take care of this problem. Using Site Authentication, you can give Google's adsense crawler access to your login-protected pages by passing it information to log into your site.

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 Google's 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 with a username, password, and a few other details, all you have to do is verify that you own the site through Google Sitemaps.

If this sounds a little complicated, don't worry -- just check out Site Authentication in your account and follow the instructions on the page. Please note that you will only have access to this feature if you've updated your AdSense login to a Google Account.

Once you've set up your authentication rule and verified ownership, it may take 1-2 weeks for our crawler to visit your site again. Your users will thank you, and so will the AdSense Crawler.
