The NYU LibGuide Accessibility guide states the importance of readability quite well:

"Making our content clear and concise benefits all our users!"

As you have time and interest, consider reviewing larger chunks of text on your guides. Follow these tips from NYU:

• Use simple and concise language
• Avoid acronyms and jargon
• Break up big blocks of text for easier reading 
• Put the main point of your text at the beginning.

You may wish to use the Hemingway App tool. It provides a readability score by grade level and provides recommendations.
