Tag Tester questions

Hi, I am looking at Tag tester and have some questions around it:

Is there value is testing lower traffic posts that might benefit more from an SEO boost as opposed to ones that are already performing well?
Does tag tester want to change the actual links as well? And if so how does that impact backlinks?
When I run an experiment is it for one page at a time? It appears I can select several of my pages but do not know what results I end up with.
Is there a video out there as a resources of any upcoming webinars? Or recorded webinars that cover this in more detail?

Thanks!

Changing tags does not always assist with the issue. The best thing to do in this situation is to edit the tags that are already on lower-performing pages to see if it helps raise pageviews.
Tags and links are not linked, so you can safely change tags without worrying about links not working.
You can run an experiment for multiple sites.
Here you go!
