Welcome to the Q&A Forum

Hi,

I also have this problem with our site with 50 duplicate pages recorded on Moz, If I do a no index, follow on Yoast will it create 404's or will I only get a 404 if i remove the tags completely?

Also is there a way to set this up for all future blog posts on yoast or will I need to do this every time I submit a new post?

Thanks

Jeh
