ContentKing's History and What It Did
Founded in 2015 in Amsterdam by Vincent van Scherpenseel and a co-founder, ContentKing pioneered continuous, real-time website crawling that flagged SEO-breaking changes within minutes rather than waiting for the next scheduled audit.
It grew to around 200 enterprise customers, including brands such as Netflix, Adidas, and H and M, out of roughly 775 total customers, before its acquisition.
The Conductor Acquisition and What Changed
Conductor, an enterprise SEO platform founded in 2006 and headquartered in New York City, acquired ContentKing in February 2022, integrating its real-time monitoring technology into Conductor's broader organic marketing platform.
ContentKing initially continued operating somewhat independently, including gaining single sign-on with Conductor, before being fully merged into Conductor's core suite starting in summer 2025.
Where ContentKing's Technology Lives in 2026
ContentKing is no longer available as a standalone product; its capabilities now live inside Conductor's platform under the name Conductor Monitoring, accessible only as part of a broader Conductor subscription.
The original contentkingapp.com domain redirects to Conductor's website, and pricing is custom and quote-based rather than the smaller-team pricing ContentKing previously offered on its own.
