Use plenty of headings
Creating headings that summarize the content of that paragraph(s) lets the user understand what that section is about before deciding whether or not they want to read it.
Use bullet points
Bulleted lists allow for optimal readability and allow users to easily understand and store that information.
Keep paragraphs short
Long paragraphs are dense and hard to scan. If you review a long paragraph, you can almost always find a place where you could break it up into two paragraphs. This makes the information easier for the user to digest.
Know your audience
Use words that your audience is familiar with. Using complex or internal jargon will most likely confuse the user. Audience appropriate language is key to allow the user to easily scan and understand the information.
Call attention to key terms and phrases
By utilizing text format tools like bolding or highlighting, you allow the user to easily find key terms/phrases within a paragraph of copy.
