External Nofollow

The “External Links Overview” plugin scans your WordPress posts and pages for outgoing external links and presents them in a searchable, filterable, and sortable table. It helps you optimize your outbound link profile and identify broken or potentially harmful links.
All plugin functions, options, and database entries use the prefix <code>seokelo_</code> to prevent conflicts with other plugins.
