A website editor is someone who helps the author of a website by looking through his or her work for mistakes that need to be fixed, sections that seem unclear, or areas that could use improvement in terms of layout, design, etc.Once there, add the people you wish to be given editing permissions typing in their email addresses into the "Add People" bar provided. Make sure that the drop-down menu next to the bar is set to "Can Edit" and then hit enter. This process may also be used in order to give people access to viewing your website if the website is set to private.
In order to allow an editor to make comments on your website directly, he or she must be given access by the owner. To do so, make sure you're logged into your Google account, and then simply click on the blue "Share" button on the top right of the page. This will open a page from which you can add any person you would like to be able to edit/view your web page.
If you no longer want a person you have given permissions to edit/view your web page, just click on the "x" that is located to the right side of their name to remove them from the permissions list. Note that they will still be able to view your website even without permissions if it is set to public.
