(J)ExR closes all references from passing weights. All external links can receive a parameter rel=”nofollow” or go through an internal redirect so that the weight of the links remains on the site. Installed and try what happens. But plugin for wordpress, even for today, very promising.

Here is what the plugin looks like (J)ExR:

(J)ExR close links nofollow CMS wordpress

So far I have not found any sensible analogues of the plugin, If anyone finds it, please post it. good luck with your work.
