Frequently Asked Questions
What is word frequency analysis?
Word frequency analysis counts how often each word appears in a text and ranks them by occurrence. It reveals patterns in writing style, identifies overused words, and helps understand the topical focus of a document. It is widely used in linguistics, SEO, content writing, and academic research.
What is the Flesch-Kincaid Grade Level?
The Flesch-Kincaid Grade Level is a readability formula that estimates the U.S. school grade level needed to understand a text. It uses average sentence length and average syllables per word. A score of 8.0 means an 8th grader should be able to understand the text. Most general-audience writing aims for grades 7-9.
What is the type-token ratio (TTR)?
The type-token ratio (TTR) measures vocabulary richness by dividing the number of unique words (types) by the total number of words (tokens). A TTR of 0.70 means 70% of words are unique. Higher TTR indicates more diverse vocabulary. It is commonly used in linguistics and language learning assessment.
What are bigrams and why do they matter?
Bigrams are consecutive two-word pairs in a text (e.g., 'machine learning', 'New York'). Analyzing bigrams reveals common phrases, collocations, and thematic patterns that single-word frequency misses. They are useful for SEO keyword research, content optimization, and understanding writing style.
What does the stop words filter do?
Stop words are extremely common words like 'the', 'is', 'at', 'which', and 'on' that carry little meaning on their own. The stop words filter excludes these from the frequency analysis and bigrams, allowing you to focus on the content-carrying words that reveal the actual topic and style of the text.
How are unusual/rare words identified?
Our analyzer compares each word against a list of the most common English words. Words that are 4+ letters long and not found in this common word list are flagged as unusual or advanced. These may include technical jargon, academic vocabulary, or rare English words that could affect readability.
How is the Flesch Reading Ease score interpreted?
The Flesch Reading Ease score ranges from 0 to 100. Higher scores mean easier reading: 90-100 is very easy (5th grade), 60-70 is standard (8th-9th grade), 30-50 is difficult (college level), and 0-30 is very confusing (graduate level). Most web content should aim for 60-70.
Can I use this for SEO content analysis?
Yes. The word frequency analyzer helps with SEO by showing keyword density, identifying overused terms, measuring reading level (Google favors accessible content), and finding relevant bigrams. Use it to ensure your target keywords appear at the right frequency without keyword stuffing.
