About the Readability Checker

What is a good Flesch score for website content?

For blog posts and website copy, a Flesch Reading Ease score between 60 and 70 is ideal. Scores above 70 are appropriate for general consumer audiences. Scores below 50 will lose many readers. Read our guide on content marketing for small business.

How do I improve my readability score?

The two most effective changes are shortening sentences and replacing complex words with simpler alternatives. Aim for sentences of 15 to 20 words. Replace: utilise with use, demonstrate with show, implement with do.

What grade level should website content be?

Aim for Grade 8 or below for general audiences. Most popular websites and newspapers write at Grade 6 to 8. Specialist content may sit at Grade 10 to 12 appropriately.

Why This Matters

Content that is hard to read loses people before they reach your call to action, and it can also hurt SEO since Google favours pages that clearly satisfy the reader's intent. Running a draft through a Flesch Reading Ease check helps you spot overly complex sentences before you publish.

Frequently Asked Questions

What is a good Flesch Reading Ease score for a website?

For most business websites, aim for 60 to 70, which corresponds to plain English that is easy for a broad audience to read. Highly technical audiences can tolerate a lower score; general consumer content should aim higher.

Does a high readability score mean the content is good?

Not on its own. Readability measures sentence and word complexity, not accuracy or usefulness. Use it alongside other checks, such as whether the page actually answers the reader's question.

How can I quickly improve a low readability score?

Break up long sentences, replace complex words with simpler alternatives, add more paragraph breaks, and use subheadings and bullet points so the page is easier to scan as well as read.
