This module makes it easy to verify domain ownership for Google Apps/Google Hosted Services(ghs) on a Drupal site using the HTML verification method. You simple copy and paste the verification string into the settings page for this module and Google will now be able to verify your domain ownership.
If you'd like a more generalized module that handles more sites then just Google apps, check out the Site Verification module.
