SEO monitoring for complex websites

Large websites often involve many people working on the site at the same time. It is important to keep an overview of everything that is happening in terms of SEO, promising optimizations or possible SEO mistakes. This can be done with the SEO tool ContentKing. This tool audits websites in real time and keeps track of adjustments on the site in an orderly manner.

What is ContentKing and how does it work?

ContentKing retrieves real-time information from Web sites. This is especially useful for websites that are so large that manual tracking is no longer possible. ContentKing provides insight into which pages have been modified and whether there are SEO bottlenecks that need to be fixed. Examples include adjusting headers or detecting broken links. ContentKing displays opportunities for SEO optimizations per page and also provides an overall overview of the SEO of the entire website.

About ContentKing

ContentKing was founded by digital marketing specialists who were looking for a tool to manage the content and SEO of complex websites. Since that tool did not exist, they decided to develop it themselves. The company was founded in 2015 and now ContentKing has offices in Amsterdam and in Brno, Czech Republic. ContentKing operates in Europe and America and the tool is used by large companies, such as Netflix, Vodafone and H&M. Its annual revenue is 1.3 million euros.
