Understanding the metrics

What these numbers mean and how to improve them.

Score (0–100)

Overall

Clarity score: the higher it is, the smoother the reading.

Goal: 70+ for an easy text.
Improve by shortening sentences and adding whitespace.

Words

Volume

Number of words detected. Used as a baseline for averages and densities.

A short text can be clear even with few paragraphs.
From ~120 words, spacing out becomes important.

Sentences

Structure

Number of sentences. Few sentences for many words = long sentences.

Aim for one main idea per sentence.
Split at “and”, “but”, “because”, “so” if it drags on.

Paragraphs

Airiness

A text without paragraphs is tiring. Add whitespace every 3–6 sentences.

1 paragraph = 1 idea.
Add line breaks on mobile.

Average sentence length

Rhythm

Ideally 12–20 words. Beyond that, the reader gets lost more easily.

Above 25 words, think “split”.
Replace subordinate clauses with 2 sentences.

Average word length

Vocabulary

The longer the words, the more technical or abstract the vocabulary tends to be.

Prefer common words when possible.
Define technical terms if needed.

Use Cases

Improve a text before publicationQuickly check if an article, webpage, or product description is easy to read, then adjust the length of sentences and vocabulary.
Make communication more accessibleOptimize an email, notice, internal document, or client message to be understood at first glance (fewer ambiguities, fewer re-reads).
Optimize SEO content without sacrificing clarityIdentify overly dense passages: clearer text often increases reading time, reduces bounce rate, and improves user experience.
Adapt a text to a target reading levelAssess whether the text is suitable for a general, school, or professional audience, and simplify where necessary.

What you get

A readability score and key statistics (average sentence length, long words, overall structure) to evaluate the clarity of your text at a glance.

Actionable tips to improve readability: shorten sentences, favor active voice, clarify transitions, and eliminate unnecessary jargon.

A more comfortable reading experience for your readers: clear text is understood faster, retained better, and gives a more professional impression.

Limits and Points of Attention

A readability score is an indicator, not a verdict: a technical text can be intentionally denser (documentation, legal, scientific).
Metrics are based on 'mechanical' signals (sentences, words): they do not replace human proofreading on content (coherence, accuracy, tone).
Readability also depends on context: titles, formatting, lists, and examples often improve more than a simple change of vocabulary.

Frequently Asked Questions

What readability score should I aim for?

For general audience content, aim for fluid text with relatively short sentences and simple vocabulary. For an expert audience, a more 'difficult' score may be normal: the goal is mainly to avoid unnecessarily complicated passages.

How can I quickly improve the readability of a text?

Start by cutting long sentences, replacing vague transitions with simple connectors, and eliminating unnecessary words. Add lists and examples when the text becomes dense.

Is it useful for SEO?

Yes: clearer content often improves engagement (longer reading, fewer back-and-forths), which enhances user experience. The goal is not to 'cheat', but to write better for humans.

Tip

If your score is average, start with a simple action: transform each sentence longer than 25–30 words into two shorter sentences. This often provides the best clarity gain in minimal time.
