Ever wonder how Google generates the unique verification code used for authorizing access to Google Webmaster Tools? There are two ways to verify your site in Webmaster Tools. One way is by adding a meta tag code to your header file and the other way is to upload a unique HTML file.
Ever wonder how Google generates that code?
Well, a Google Groups thread discusses some hints on how it is made. Googler, Susan Moskwa, said the file is unique based on two factors:
- The web site URL
- The email address used to register on webmaster tools
So, if you change the email address you used to verify your site in Webmaster Tools, you will need to reupload a new verification file, because the code will be different.
