Why Analyze Your Text?
Readability has a direct impact on whether readers finish what you write. Marketing copy, blog posts, product descriptions, and educational content all benefit from matching audience reading level. Keyword density signals content focus to search engines and reveals over-used phrases that hurt clarity. Sentence and syllable averages help you tighten dense paragraphs without losing substance.
Common use cases
- Tuning blog posts to a target audience reading level
- Auditing landing pages for clarity and keyword focus
- Editing academic papers down to required complexity
- Improving readability of legal and policy documents
- Optimizing content for SEO without keyword stuffing
- Coaching students on plain-language writing
- Comparing first drafts to revised versions for clarity gains
- Profiling translated content to ensure parity with the source
Understanding Flesch Reading Ease
Flesch Reading Ease ranges from 0 to 100. Scores above 70 are easy to read for most adults. Scores below 30 are difficult and typically college-level. The companion Flesch-Kincaid Grade converts the same inputs into a US grade-level number, making it easy to align content with audience expectations.
Keyword Density Without Stuffing
Modern search engines penalize unnatural keyword repetition. Healthy density for a primary keyword is typically 1-2 percent. Use the keyword density panel to confirm focus terms appear often enough for relevance signals while avoiding over-optimization that hurts ranking and readability.
Tips & best practices
Aim for Flesch 60-80 for general audiences
Marketing and editorial content usually performs best in this range, balancing clarity and substance
Watch sentences over 25 words
Long sentences raise the Gunning Fog score. Break them up to improve flow without losing meaning
Compare drafts side by side
Run analysis on first and final drafts and confirm scores moved in the right direction
Use grade level for compliance
Healthcare, legal disclaimers, and education sometimes specify a maximum grade level. Use the estimated grade as a quick gate
Treat keyword density as a guide, not a target
Write naturally first, then verify density, rather than padding text to hit a percentage

Frequently Asked Questions
What does the Flesch Reading Ease score mean?
Flesch Reading Ease scores range from 0 to 100. Higher scores mean easier reading. Scores above 70 are easy for general audiences. Scores between 60 and 70 are considered standard. Scores below 30 are difficult and typically suit college-educated readers.
How is keyword density calculated?
Keyword density is the percentage of times a word appears relative to the total word count. The analyzer filters common stop words and short tokens, then ranks the remaining words by frequency. Healthy density for a primary keyword is typically 1-2 percent.
How accurate is the syllable count?
The analyzer uses a heuristic syllable counter that handles English text reliably for typical content. Edge cases like proper nouns and uncommon words can vary, but the average across a paragraph is accurate enough for readability calculations.
Why are there multiple readability scores?
Different formulas weigh sentence length, syllables, and complex words differently. Flesch is general-purpose. Gunning Fog emphasizes complex words. SMOG focuses on polysyllabic words. ARI uses character counts. Comparing scores triangulates a more reliable assessment.
What grade level should I target?
Marketing and editorial content typically targets grade 7-9 for accessibility. Technical and academic content often lands at grade 12 or college level. Match grade level to your audience: lower for general readers, higher for specialists.
