We rank web sites on four criteria: Readability – How readable is the content Passive Language – active language communicates clearly. What percent of sentences are passive? Long Sentences – what percent of all sentences are considered too long? Word Complexity Density – complex words make Web pages hard to understand. Collectively, these metrics tell us how clear or complex your website content is.
