1. Flesch–Kincaid readability tests

Flesch–Kincaid readability tests indicate the difficulty of an English passage. It consists of two tests: Flesch Reading Ease and Flesch-Kincaid Grade Level.

Flesch Reading Ease: The test is done to understand the readability factor of a text. A higher score means easy-to-read, while a lower score means difficult-to-read.

Each website has targeted audience, for example a fashion enthusiast would rarely like visit a gambling site or vice-versa. So, write accordingly. While some other sites like news and social media websites can be used by anyone, there’s a high need to make use of more general words.
