• Site Authentication using META tags: For those of you who cannot upload an authentication file to your site, such as a blog, you will now be able to authenticate your site in Site Explorer by including an authentication key as part of a META tag on the home page of your site. This is in addition to the existing mechanism of putting a file on your site home directory.

• Detailed Authentication Errors: We now provide detailed errors on authentication failures, making it much easier to diagnose possible problems.

• Delete URLs: For your authenticated sites, you can now delete any URLs from the index. Simply locate the URL in Site Explorer and click on the ‘Delete URL’ button. The URL and all its subpaths will be deleted shortly thereafter. This is meant to work in conjunction with the robots.txt file while providing greater responsiveness. Please continue to use the robots.txt protocol to ensure that our crawler does not crawl pages you want to keep out of our index.
