Q: I'm getting an error when trying to verify my site with a file, even though my file is visible in my browser.
Look at the specific error that Webmaster Tools is showing and read the help content
for that error. Check that the file returns only the required content
(and does not include HTML code, images, or scripts such as counters). The easiest way to do this is to use "view-source" in your browser.
Q: Does it matter whether my Webmaster Tools verification meta tag is in HTML or XHTML?
No. We'll be able to find your meta tag no matter which format you use. Webmaster Tools provides the meta tag in XHTML by default.
Q: I'm using a hosting service for my site that prevents me from adding meta tags or uploading HTML files. How can I verify my site?
Try one of the other verification methods and get in touch with your hosting service.
Q: I'm using a hosting service for my site that uses frames / "masked redirects" / "masked forwarding." How can I verify my site?
A: The meta tags or the HTML file must be hosted directly with your domain name. Using a forwarding service that uses frames will generally not allow you to verify your site in Webmaster Tools. Keep in mind that this kind of forwarding will also generally make crawling, indexing and ranking of your content using your domain name impossible. We recommend always hosting your content directly using your domain name.
Q: How can I give someone else access to my Webmaster Tools account?
A: Each person that needs to access data for your site should create their own Webmaster Tools account and verify that site in their own account. It's fine for a site to have multiple verification meta tags or HTML files; there should be one meta tag or file per account. You can also delegate ownership to others directly.
