I am searching for a code or better a wordpress plugin to set automatically all links only to a certain domain (and of course to all of its subpages) to "nofollow".
F.e. the plugins I found and their problems:
https://wordpress.org/plugins/nofollow/ Has only "A nofollow option for individual blogroll links" -> so no possibility to set only a certain domain to nofollow which is part of normal articles
https://wordpress.org/plugins/nofollow-links/ Again only general nofollow to domains in the blogroll (or normal links in the articles too? In my understanding a blogroll is a linklist on the sidebar)
wordpress.org/plugins/nofollow-all-external-links Can only give nofollow to all external links, not to a certain domain only
And so on. Anybody with a plugin which allows me to set only a certain domain with its subpages to nofollow?
