Description
The Spinner addon connects MainWP to third-party content spinning services, producing rewritten and unique versions of each post before bulk publishing to the child sites managed by the dashboard. Designed for agencies and SEO professionals who manage WordPress site networks, it prevents duplicate content when the same editorial material must be distributed across multiple installations controlled by MainWP, keeping the entire workflow concentrated in a single management screen.
