Q. Why couldn't I enter the meta tags in the "site URL" section when filling out the website info?

The meta tag section in the "site URL" panel under the website info is strictly for viewing purpose, it allows user to view the meta tag of the url being selected. It is not meant to change and modified the meta tag of url or local file. To modified the meta tags of the local HTML files, please use the meta tag editor included in the submission v7.0.

For normal submission purpose, you can safely ignore this meta tag section under the "site URL" panel. You will not be required to fill in anything in this area and nothing will be saved in this area.
