Hi Yannick,
This is just a question so no rush.
Some years ago I used content tags for some articles in my Joomla website. This turned out to cause SEO issues (duplicate content) so I got rid of all the content tags and decided to never use them again.
Now, however, I would really like to be able to use 1 or 2 content tags in Joomla just to be able to filter content for applying templates to specific pages (YOOtheme Pro, dynamic content templates). This means I would not generate any pages based on tags (no modules, menu items etc). But I'm afraid that Joomla still creates URLs based on the content tags and that Google will pick them up.
So my question to you is:
Can 4SEO prevent Google from picking up any URLs that possibly would be generated from those content tags?
I'm not going to create any content tags if you advice against it. Then I will just have to apply my templates manually.
(I also posted my question about content tags in the Joomla FB group which also generated a couple of comments about 4SEO. Just FYI: https://www.facebook.com/groups/joomlanospam/posts/10158389744020997).
