Frequently Asked Questions
This tool uses the Flesch-Kincaid Reading Ease formula. It calculates readability based on the average sentence length and the average number of syllables per word. A higher score means the text is easier to read. For web content, a score of 60-70 is often considered a good target.
Clear, easy-to-read content performs better. For SEO, it reduces bounce rates and increases time on page, which are positive ranking signals. For AEO (Answer Engine Optimization), simple language is more likely to be selected for featured snippets and voice search answers. Accessible content reaches a wider audience and builds trust.
The grade level is calculated using the Flesch-Kincaid Grade Level formula. It analyzes the same factors as the reading ease score (word length and sentence length) but presents the result as a U.S. school grade level. For example, a score of 8.0 means that an eighth grader can understand the text.
These formulas provide a strong guideline, but they are algorithmic approximations. Syllable counting in English can be complex, and the formulas don't account for context, jargon, or brand voice. Use these scores as a helpful metric, not an absolute rule. The goal is clear communication, and this tool helps you measure that.
