When I search
site:[example].com in Google for my blog, the majority of the pages that are being indexed are "pretty links" to external sites.
I created these links using the Pretty Links plugin so that I can make links to external sites look nice and clean, and also so I can track how many people click through to those sites from my blog.
But many of them were created before I understood anything about follow/no follow links. As I've learned more, I realised this isn't ideal and have gone and changed each of these links to "no follow" , but this hasn't stopped then from being indexed by Google.
How can I stop these links from being index?
