Frequently Asked Questions
What is a good Flesch Reading Ease score?▼
For web content, aim for 60-70 (8th-9th grade level). Scores of 70-80 are "fairly easy" (7th grade), and 80-90 are "easy" (6th grade). Academic or technical content may have lower scores (30-50), but general web content should be accessible to most readers.
Does readability affect SEO?▼
While readability is not a direct Google ranking factor, it strongly correlates with SEO success. Readable content leads to longer time on page, lower bounce rates, and higher engagement, all of which are positive user signals. Google aims to rank content that best satisfies user intent.
What is the Flesch-Kincaid Grade Level?▼
The Flesch-Kincaid Grade Level indicates the US school grade level needed to understand the text. For example, a grade level of 8 means an average 8th grader (13-14 years old) should be able to understand the content. Most popular websites write at a 6th-8th grade level.
How can I improve readability?▼
Use shorter sentences (15-20 words average), choose simpler words over complex ones, break up long paragraphs, use bullet points and subheadings, avoid jargon and passive voice, and write in a conversational tone.
