Co-link policies enforce strict rules on external citations within generated outreach articles. The system maintains a banned domain list of direct competitors, using regex matching to immediately fold and reject drafts that link to or mention competing brands. In contrast, approved domains serve as a recommended shortlist of credible, non-competing authorities rather than a rigid whitelist, preventing a repetitive citation footprint. This dual-layer check ensures surrounding links appear organic to search engines without leaking authority to market rivals.
