Word Count & Reading Time
Total word count and estimated reading time at average adult reading speed (238 wpm).
Flesch Reading Ease
Score from 0–100 measuring how easy the content is to read. 60–70 is the web standard. Below 50 is considered difficult.
Flesch-Kincaid Grade Level
US school grade level required to understand the content. Most web content performs best at grade 7–9.
Sentence & Paragraph Stats
Average sentence length, average paragraph length, and the longest sentence — key readability signals.
Passive Voice
Percentage of sentences using passive voice. Active voice is clearer and more engaging. Aim for under 10%.
Transition Words
Percentage of sentences that begin with or contain a transition word. Transitions improve flow and are a Yoast readability signal.
Keyword Density
Top 15 single keywords and top 10 keyword phrases (bigrams) by frequency, with density percentages. Stop words are excluded.
Focus Keyword Analysis
If you provide a focus keyword, we check whether it appears in the title, H1, meta description, and first 100 words.
Heading Structure
Full H1–H6 outline extracted from the page, with counts per level and hierarchy warnings.
Images & Alt Text
Total image count and how many are missing alt text — an accessibility and SEO issue.
Internal & External Links
Total link count split by internal and external — important for crawlability and authority signals.
Content-to-HTML Ratio
What percentage of the page's total code is actual text content. Very low ratios can indicate thin or bloated pages.
Sentiment Analysis
Optional: classifies content tone as positive, neutral, or negative based on word-level analysis.
Duplicate Sentence Detection
Optional: finds repeated sentences that may indicate content quality issues.
Readability Suggestions
Optional: specific, actionable suggestions for improving readability with example sentences.
Google's Helpful Content system evaluates whether content is written for people first, with E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) as the underlying framework. Content that is hard to read, poorly structured, or thin on substance is increasingly filtered out of competitive rankings.
Readability directly affects dwell time and bounce rate — two behavioral signals that correlate strongly with rankings. Content written at the right grade level for your audience keeps visitors reading longer. Proper heading structure helps both users and crawlers understand page hierarchy. And keyword density analysis ensures you're neither ignoring your target terms nor stuffing them.
Low readability score
Break long sentences into shorter ones. Aim for an average sentence length under 20 words. Use common words where possible and avoid unnecessary jargon.
High passive voice
Rewrite passive constructions in active voice. "The page was optimized by us" becomes "We optimized the page." Active voice is clearer and more direct.
Missing focus keyword in H1
Your H1 is one of the strongest on-page SEO signals. If your focus keyword isn't in the H1, rewrite it to include a natural variation.
Low transition word usage
Add transitional phrases (however, therefore, in addition, as a result) to improve content flow. Aim for transitions in at least 30% of sentences.
Missing alt text on images
Every image should have descriptive alt text. This helps screen reader users and gives search engines context about the image content.
Thin content (low word count)
Pages with under 300 words rarely rank competitively. Aim for comprehensive coverage of your topic — depth beats keyword repetition.
Low content-to-HTML ratio
A very low ratio (under 10%) often means too much boilerplate code relative to content. Audit your template for unnecessary markup.
What word count should I aim for?
It depends on the topic and intent. Informational content typically performs best at 1,000–2,500 words. Product pages can rank well at 300–600 words. Focus on covering the topic comprehensively rather than hitting a number.
What is a good Flesch Reading Ease score?
For most web content, aim for 60–70 (Standard). News articles target 60+. Technical content can go lower. A score below 30 is considered very difficult and will lose most readers.
What keyword density should I target?
There is no magic number. Most SEO practitioners target 1–2% for a primary keyword. Anything over 3–4% risks looking like keyword stuffing. Focus on natural usage and synonyms.
Should I use passive voice?
Passive voice has its place but overuse makes content feel distant and harder to read. Keep it under 10% of sentences. Some technical and scientific writing naturally uses more passive voice.
What is content-to-HTML ratio?
It is the percentage of a page's total source code that is plain text content. Search engines can read all your code, so a very low ratio (under 10%) may indicate thin content relative to template overhead.
Does the pasted text mode analyze headings and links?
No — heading, link, image, and meta tag analysis requires fetching the actual page HTML. Use the URL mode for full structural analysis.
