What are Flesch-Kincaid Scores?

How to Improve Your Scores
Shorten Sentences
Both scores heavily weight sentence length. Break long sentences into shorter ones. Aim for 15-20 words per sentence.
Use Simpler Words
Replace multi-syllable words with shorter alternatives. "Use" beats "utilize", "help" beats "facilitate".
Remove Filler Words
Cut unnecessary modifiers and redundant phrases. "Very unique" becomes "unique", "absolutely essential" becomes "essential".
Active Voice
Active voice is typically shorter and clearer. "We analyzed" instead of "The data was analyzed by our team".
