What is keyword density and why it matters
Keyword density is the percentage of times a word or phrase appears relative to the total word count of a page. It used to be a primary ranking signal, and some writers obsessed over hitting an exact percentage. Today, search engines are far smarter — they understand topics and intent — so cramming a keyword unnaturally (keyword stuffing) hurts more than it helps. This free checker shows your word frequency and flags any term that appears suspiciously often.
A healthy article reads naturally. As a rough guideline, if a single keyword exceeds ~3% density, it's worth reviewing whether the text still reads well or feels forced. Use this tool to spot accidental repetition, balance your phrasing, and make sure your target keyword appears enough to be relevant without tipping into over-optimization.
How to use the results
Look at the top terms: your main keyword and close variants should appear naturally near the top, alongside topically-related words. If filler or unintended words dominate, tighten your writing. Export the table as CSV to track changes across drafts. For consistently optimized articles at scale, aithor handles intent, structure and keyword balance automatically.
