Readers leaving your site through citations, partner blogs, or research papers often expect your article tab to stay put while references open beside it. Manually adding target=”_blank” and safe rel values across hundreds of links is fragile. This module filters post content and approved comment bodies so outbound links—detected relative to your site’s canonical host—gain new-tab behavior and hardened rel attributes without touching the database HTML on every save (behavior depends on filter timing; cached output still reflects results).

Pair with internal linking strategy: only true external hosts should receive these attributes; subdomains and alternate domains need testing per multisite and CDN mapping.
