Anyone who can tell me how I can disable the component users to provide search engines the noindex, means:
<meta name=robots content="noindex" />
for example in all Joomla instances, the URL
/component/users/
Is there a common way to set the noindex?
It looks like you have activated Search Engine Friendly URLs
in this case you need to add to your robots.txt
User-agent: *
# disallow login from of joomla
Disallow: /component/users/
You can use the robots.txt file to disallow the indexing. Try using this directive in your robots.txt file.
User-agent: *
Disallow: /*?option=com_users*
The cons of this approach is that not all search engines crawlers observe the wildcard syntax. I think this will do the trick with the major ones (Google, Bing and Yahoo).
I found this and this useful articles about robots.
Another way that you could try is in every menu item, that calls the com_users component, in the metadata tab, set the robots option to No Index.
