For this reason, it’s a good idea to use short, concise sentences whenever possible. For example, you could try breaking up a single long sentence into two shorter ones. Similarly, instead of using big words to sound more intelligent try using smaller ones that are easier to understand.

Tip 2: Make Sure Your Content Is Easy to Scan

Making sure your website’s content is digestible to any reader by using shorter paragraphs and lots of headings and sub-headings is a great way to improve its readability. This allows you to stay focused and deliver ideas in chunks that are easy to scan.

Tip 3: Use a Conversational Tone

Writing in a conversational tone automatically increases your content’s readability. For instance, it forces you to use active voice sentences more than passive voice ones. So, instead of writing something like At dinner, six shrimp were eaten by Jane you’d be more likely to write Jane at six shrimp at dinner.

In addition to this, using a conversational tone will also make you seem more human and captivate your audience’s attention right off the bat. And as a result of that, you’re more likely to generate user engagement and encourage readers to start discussions.


By establishing a balance in your written online content, you can significantly improve your Flesch Kincaid readability scores and make sure your content is easier to understand by more people. Let’s quickly recap the tips you can adopt to improve your Flesch Kincaid reading ease score:
