How does the word counter work?

ToolSuite Word Counter analyzes your text in real time as you type or paste content. It uses JavaScript running in your browser to count words (splitting on whitespace and punctuation), characters, sentences (detecting period, exclamation, and question mark boundaries), and paragraphs. All counting happens locally with 100ms debounced updates for smooth performance.

What readability scores do you calculate and what do they mean?

We calculate six industry-standard readability formulas: Flesch Reading Ease (0-100 scale, higher is easier), Flesch-Kincaid Grade Level (U.S. grade equivalent), Gunning Fog Index (years of education needed), Coleman-Liau Index (character-based grade level), SMOG Index (based on polysyllabic words), and Automated Readability Index (character and word counts). Each formula uses different text properties to estimate difficulty.

What is a good Flesch Reading Ease score?

For web content, aim for 60-70 (8th-9th grade level). Scores above 70 are easy to read and suitable for general audiences. Scores of 50-60 work for moderately complex topics. Academic and technical writing typically scores 30-50. Most bestselling novels score 60-80. The ideal score depends on your audience.

How is keyword density calculated?

Keyword density is the percentage of times a word or phrase appears relative to the total word count. A keyword appearing 10 times in a 1,000-word article has 1% density. We analyze 1-word (unigrams), 2-word (bigrams), and 3-word (trigrams) phrases, filtering common stop words like 'the', 'and', 'is' to show meaningful terms.

Is my text stored or sent to a server?

No. ToolSuite Word Counter processes everything client-side in your browser. Your text never leaves your device. No data is transmitted, stored, or logged. You can verify this by checking your browser's Network tab or using the tool offline.

What is the Gunning Fog Index?

The Gunning Fog Index estimates the years of formal education needed to understand text on first reading. It's calculated using average sentence length and the percentage of complex words (3+ syllables). A score of 12 means high school senior level. Newspapers typically score 11-12, while academic papers score 15-20. For web content, aim for 8-12.

How do I check if my writing meets a grade level requirement?

Use the Flesch-Kincaid Grade Level score, which directly maps to U.S. school grade levels. A score of 8.0 means 8th-grade reading level. For health content, aim for 6th-grade level. For business communication, 8th-10th grade. For academic papers, 12th grade or higher. The Coleman-Liau and ARI scores provide alternative grade-level estimates.

What character limit should I use for meta descriptions?

Google typically displays 150-160 characters for meta descriptions on desktop and 120-130 on mobile. The character limit progress bar shows your text against the 160-character desktop limit. For Twitter/X posts, stay under 280 characters. LinkedIn posts perform best under 1,300 characters.

How accurate is the reading time estimate?

The reading time estimate uses an average reading speed of 200-250 words per minute for adults. This is accurate for most web content. Technical or academic text may take longer. The speaking time estimate uses 130 words per minute, which is standard for presentations and speeches. Both are widely-used industry averages.

Can I analyze keyword density for SEO?

Yes. The keyword density panel shows the most frequent 1-word, 2-word, and 3-word phrases in your text with their occurrence count and percentage. For SEO, primary keywords should appear at 1-2% density. Use 2-word and 3-word analysis to find natural long-tail keyword opportunities. Stop words are automatically filtered out.
