Text analysis & writing metrics • 2026 standards
Reading Time: \( \text{Time (minutes)} = \frac{\text{Words}}{200} \) (average adult reading speed)
Word Density: \( \text{Density (\%)} = \frac{\text{Target Word Count}}{\text{Total Word Count}} \times 100 \)

Word count, character count, reading time, and sentence structure are fundamental text metrics that help evaluate content quality and readability.
Flesch Reading Ease = 206.835 - (1.015 × ASL) - (84.6 × ASW). Higher scores indicate easier reading.
Keyword density is calculated as (keyword frequency / total word count) × 100. Optimal density is 1-3% for search engines.
If a text contains 800 words and the average reading speed is 200 words per minute, what is the estimated reading time?
The answer is C) 4 minutes. Using the formula: Reading Time = Total Words ÷ Words Per Minute
Reading Time = 800 ÷ 200 = 4 minutes
This calculation assumes an average reading speed of 200 WPM, which is the standard for adult comprehension.
Reading time calculations help content creators understand how long their audience will spend reading. This metric influences engagement rates and user experience. Different audiences may have varying reading speeds.
WPM: Words Per Minute - measure of reading speed
Reading Time: Estimated duration to read text
Comprehension Rate: Speed at which text is understood
• Standard reading speed: 200 WPM
• Skilled readers: 300-400 WPM
• Children: 100-150 WPM
• Remember: 200 WPM is average speed
• Complex text reduces reading speed
• Use reading time to optimize content
• Using incorrect reading speed assumptions
• Not accounting for text complexity
• Forgetting to adjust for audience
A paragraph contains 120 words and 6 sentences. Calculate the average words per sentence and determine if this falls within optimal readability guidelines.
Average words per sentence = Total words ÷ Total sentences
Average = 120 ÷ 6 = 20 words per sentence
Optimal readability guidelines suggest 15-20 words per sentence for good comprehension. This paragraph falls perfectly within the optimal range, indicating good readability and flow.
Sentence length significantly impacts readability. Shorter sentences are easier to process, while longer sentences can convey complex ideas but may reduce comprehension. The 15-20 word range balances clarity with expressiveness.
Readability: Ease of understanding written text
Comprehension: Understanding of written content
Sentence Length: Number of words in a sentence
• Optimal: 15-20 words per sentence
• Shorter sentences improve clarity
• Vary sentence lengths for rhythm
• Mix short and long sentences
• Keep complex ideas in shorter sentences
• Use longer sentences for emphasis
• Using consistently long sentences
• Not considering audience complexity
• Ignoring readability guidelines
A blog post contains 1,200 words. If the target keyword appears 15 times, calculate the keyword density and determine if it falls within optimal SEO guidelines. Also calculate how many times the keyword should appear for optimal density.
Current keyword density calculation:
Density = (Keyword occurrences ÷ Total words) × 100
Density = (15 ÷ 1,200) × 100 = 1.25%
Optimal SEO keyword density: 1-3%
Current density (1.25%) falls within optimal range.
For optimal density:
At 1%: 1,200 × 0.01 = 12 occurrences
At 2%: 1,200 × 0.02 = 24 occurrences
At 3%: 1,200 × 0.03 = 36 occurrences
The current 15 occurrences (1.25%) is appropriate for SEO.
Keyword density optimization is crucial for SEO. Too little density may not signal relevance, while too much can appear spammy. The 1-3% range provides optimal balance for search engines.
Keyword Density: Percentage of keyword occurrences
SEO: Search Engine Optimization
Optimization: Improving search visibility
• Optimal density: 1-3%
• Avoid keyword stuffing
• Focus on natural integration
• Use keyword variants and synonyms
• Place keywords naturally in text
• Focus on content quality over density
• Over-optimizing for keyword density
• Forgetting about user experience
• Not using keyword variations
A writer wants to create a 600-word article with optimal paragraph structure. If they follow the guideline of 3-5 sentences per paragraph and 15-20 words per sentence, calculate the optimal number of paragraphs and sentences for the article.
For optimal paragraph structure:
Average words per sentence: (15 + 20) ÷ 2 = 17.5 words
Average sentences per paragraph: (3 + 5) ÷ 2 = 4 sentences
Average words per paragraph: 17.5 × 4 = 70 words
Optimal number of paragraphs: 600 ÷ 70 ≈ 8.6 ≈ 9 paragraphs
Optimal number of sentences: 600 ÷ 17.5 ≈ 34 sentences
Alternative structure: 8 paragraphs with 4-5 sentences each, totaling approximately 32-40 sentences for 600 words.
Paragraph structure affects readability and user engagement. Proper structure helps readers process information and improves content flow. These calculations provide guidelines for optimal content organization.
Paragraph Structure: Organization of sentences in text
Readability: Ease of reading and understanding
Content Flow: Logical progression of ideas
• 3-5 sentences per paragraph
• 15-20 words per sentence
• Maintain consistent structure
• Use shorter paragraphs for digital content
• Vary structure for visual interest
• Ensure each paragraph has single focus
• Creating overly long paragraphs
• Not considering screen reading habits
• Forgetting to vary paragraph lengths
Which of the following Flesch Reading Ease scores indicates text that is easiest to read?

• 90-100: Very easy (5th grade level)
• 60-70: Standard (8th-9th grade level)
• 30-50: Difficult (10th-12th grade level)
• 0-30: Very difficult (college level)
A score of 90 represents text that is very easy to read and understand.
Readability metrics help writers assess how accessible their content is to different audiences. The Flesch Reading Ease score considers sentence length and word complexity to determine reading difficulty.
Flesch Reading Ease: Measure of text readability
ASL: Average Sentence Length
ASW: Average Syllables per Word
• Higher scores = easier reading
• Target audience affects optimal scores
• 60-70 is good for general audiences
• Aim for 60-70 for general audiences
• Use 70-80 for business writing
• Consider audience education level
• Confusing high scores with difficulty
• Not considering target audience
