Keyword Density Checker — frequently asked questions
What is keyword density?
It is how often a word or phrase appears relative to the total word count, shown as a percentage. For example, a term used 5 times in a 500 word article has a density of one percent.
What density should I aim for?
There is no exact target Google rewards, but keeping your main keyword in a natural range, often cited around one to two percent, is sensible. Write for readers first and use density as a sanity check, not a rule.
Can high keyword density hurt my rankings?
Yes, cramming a keyword unnaturally can read as stuffing, which search engines may treat as spam. This tool helps you catch terms that are repeated too aggressively so you can rephrase them.
