The Word Counter is a free copywriting audit tool designed to count words, characters, sentences, and paragraphs in real-time. It computes reading times, speaking times, and keyword density percentages to optimize content layout. High-quality content is a major factor in search engine optimization. Writing too little text can result in a thin content penalty, while overusing keywords (keyword stuffing) can trigger search filters. Our free Word Counter provides real-time analysis of your text, showing you the exact word count, character count, and keyword density. Copywriters, bloggers, students, and SEO specialists use this tool to optimize article lengths, verify word count guidelines, and write balanced content.
Monitor character counts with and without spaces. This is essential for drafting social media posts, Meta descriptions (155-160 character limit), and page titles (50-60 character limit). Estimates engagement duration based on standard reading speeds (approx. 200 words per minute) and speaking speeds (approx. 130 words per minute). Shows the percentage of times specific words appear in the text, helping you target optimal keyword density (typically 1% to 2%) and avoid spam flags. Keep track of text structure to ensure readability and flow.
Simply type or paste your text into the input field above. The word count, character count, and density analyses update instantly as you type.
