Word count, readability, and keyword density — what the numbers mean
A quick guide to the metrics in the analyzer.
Use a word counter with a readability score
A plain word counter tells you how long a text is, but not how easy it is to read. Our free word counter with readability score pairs the basics — words, characters, sentences, paragraphs — with a Flesch Reading Ease score and US grade level, so you get length and clarity in one pass.
What is a Flesch Reading Ease score?
Flesch Reading Ease runs from 0 to 100. A score of 90+ is very easy to read, 60–70 is plain English for most adults, and below 30 is very difficult. The analyzer doubles as a Flesch reading ease calculator: paste your text and the score, its label, and the grade level update instantly.
Check keyword density before you publish
The built-in keyword density checker counts every word of three letters or more (ignoring common stop words) and lists the ten most frequent keywords with their share of all words. Use it to spot accidental repetition, or to check how often your target phrase actually appears.
How many characters are in my essay?
Wondering how many characters are in your essay, tweet, or meta description? The analyzer counts characters with and without spaces, so you can hit a 280-character limit or a 160-character meta description without guessing. It also reports unique words — a useful proxy for vocabulary range in academic writing.
Pair the analyzer with the reading time calculator to estimate how long your draft takes to read, and run the title through the SEO headline checker before you publish.
