Depending on what kind of site you have and what kind of content you are writing, it may be helpful to determine and consider the readability of your content. How well do your sentences flow? How do your words interact with one another? These factors, among others, determine how easily readers consume written information.
The Flesch-Kincaid Readability Tests were developed to determine levels of difficulty for reading a given passage of text. The Flesch-Kincaid Reading Ease formula assigns a score for how easy something is to read; a higher score indicates easier reading. The Flesch-Kincaid Grade Level formula scores a text according to U.S. grade level (or general years of education received.) The two scores are indirectly related: a higher reading ease score generally corresponds to a lower grade level score, and vice versa.

Not all types of content should aim for the highest possible Flesch-Kincaid Reading Ease score. Literary works such as novels, short stories, poetry, etc., often do not follow normative writing conventions and are not necessarily written with comprehension ease as a top priority. However, non-fictional information including news articles, instructional documentation, and reference material are all types of content that could benefit from considering readability scores. The goal is not to dumb it down to the lowest possible grade level, but rather to bear in mind the clarity of writing you are presenting to readers.
