Entity Maturity is a measurement of how well established an Entity is in Google’s algorithms and Knowledge Graph. It measures the level and accuracy of Google’s understanding, its confidence in that understanding and the stability of the information demonstrates within Google’s ecosystems.
The measurement draws data from multiple sources including Google SERPs, Google APIs and assesses that data using a proprietary algorithm. Developed by Kalciube, Entity Maturity was introduced in 2021. Also known as Kaliscore.
