Did you know there’s a way to measure the readability of your docs? There’s a measure called the Flesch Readability Test which measures both the ease of reading your material as well as estimates the grade level required to understand your material.
Find ways to employ it in customer communications (i.e. emails), UI notices, and even in your own writings!
Want to use it? Unfortunately, Docs itself no longer supports it. But you can either throw it into Microsoft Word or use an online reader which is compatible.
