Our wordpress was built using Divi builder. I have seen Yoast as a plugin on our site. If you point me in the right direction, I most likely could make it happen. I appreciate all the support. Thanks.

How would I noindex them? I tried searching behind the scenes in wordpress where I listed the tags, but was unable to find?

If you already have duplicate pages created from tags on a blog post... can you go back and noindex them to have all the duplicate pages eliminated???
