Thursday, October 01, 2009 at 10:02 AMIf you use Webmaster Tools, you're probably familiar with verifying ownership of your sites. Simply add a specific meta tag or file to your site, click a button, and you're a verified owner. We've recently made a few small improvements to the process that we think will make it easier and more reliable for you.
The first change is an improvement to the meta tag verification method. In the past, your verification meta tag was partially based on the email address of your Google Account. That meant that if you changed the email address in your account settings, your meta tags would also change (and you'd become unverified for any sites you had used the old tag on). We've created a new version of the verification meta tag which is unrelated to your email address. Once you verify with a new meta tag, you'll never become unverified by changing your email address.
We've also revamped the way we do verification by HTML file. Previously, if your website returned an HTTP status code other than 404 for non-existent URLs, you would be unable to use the file verification method. A properly configured web server will return 404 for non-existent URLs, but it turns out that a lot of sites have problems with this requirement. We've simplified the file verification process to eliminate the checks for non-existent URLs. Now, you just download the HTML file we provide and upload it to your site without modification. We'll check the contents of the file, and if they're correct, you're done.
We hope these changes will make verification a little bit more pleasant. If you've already verified using the old methods, don't worry! Your existing verifications will continue to work. These changes only affect new verifications.
Some websites and software have features that help you verify ownership by adding the meta tag or file for you. They may need to be updated to work with the new methods. For example, Google Sites doesn't currently handle the new meta tag verification method correctly. We're aware of that problem and are working to fix it as soon as we can. If you discover other services that have similar problems, please work with their maintainer to resolve the issue. We're sorry if this causes any inconvenience.
This is just the first of several improvements we're working on for website verification. To give you a heads up, in a future update, we'll begin showing the email addresses of all verified owners of a given site to the other verified owners of that site. We think this will make it much easier to manage sites with multiple verified owners. However, if you're using an email address you wouldn't want the other owners of your site to see, now might be a good time to change it!
