Clear writing converts. Passive voice, overly long sentences, and filler phrases are the three most common patterns that make content feel vague and unconvincing. This clarity checker analyzes every sentence and assigns a score based on the density of these patterns. Passive voice is flagged separately from long sentences (over 25 words) and filler phrases such as "in order to", "due to the fact that", and "it is important to note" — giving you a clear breakdown of exactly which patterns are reducing your score.
For SEO writers, clarity directly affects E-E-A-T signals — Google's quality raters specifically look for writing that is "accurate and clear" as part of trustworthiness assessment. For students, passive voice is the most commonly penalized pattern in academic essay writing. The tool provides per-sentence fix suggestions rather than a single global score, so you can prioritize the highest-impact edits first instead of editing blindly. Pair it with the readability checker to measure Flesch Score and grade level, and the grammar checker to catch punctuation and syntax errors alongside clarity issues.
Passive voice reverses subject and object: "The report was written by the team" instead of "The team wrote the report." It makes writing feel indirect and weaker. Most style guides recommend active voice for clarity and engagement.
Filler phrases add length without meaning: "very", "really", "in order to", "due to the fact that", "it should be noted that". Cutting them typically makes sentences 15–25% shorter with no loss of meaning.
Above 80 is strong. 60–80 is average and typical of published blog content. Below 60 indicates dense passive or filler-heavy writing that would benefit from focused revision.
