Understanding the Metrics
Scored from 0 to 100. Higher scores indicate content that is easier to read. A score between 60 and 70 is considered acceptable for the general public.
Translates the reading ease score into a U.S. school grade level. An 8.0 means that an eighth-grader can understand the document. Aim for 7th to 9th grade for web content.
Sentences containing more than 20 words are flagged as "Hard," and over 25 words as "Very Hard." Breaking these up reduces cognitive load for readers.
Optimization Guide
Key Concepts
- Syllable Density: Words with many syllables heavily penalize your Flesch score. Use simpler synonyms where possible (e.g., "use" instead of "utilize").
- Sentence Length: Long, run-on sentences lose readers. Punctuate frequently.
- SEO Impact: Search engines favor content that answers queries efficiently. Highly readable content reduces bounce rates, signaling high quality.
Best Practices
- Filter the Data: Use the table filter to isolate "Very Hard" sentences and tackle them first.
- The Rule of One: Try to restrict each sentence to one core idea.
- Formatting Matters: Combine short sentences with bulleted lists and headers to make pages scannable.
