The Keyword Density & Frequency Analyzer scans your text and calculates how often your target keyword or phrase appears relative to total word count, helping you stay within the commonly recommended 1-3% density range without over-optimizing. Paste in a draft article or existing page copy and instantly see keyword counts, density percentages, and frequency for related terms too, so you can spot both under-optimization and keyword stuffing before publishing. This tool is built for content writers drafting SEO-focused articles, SEOs auditing existing pages, and marketers checking copy against a target keyword strategy. Everything runs instantly in your browser - no upload, no signup, completely free. Keyword density is a rough heuristic rather than a strict ranking rule these days, since modern search engines rely more on semantic relevance and natural language understanding, but tracking it still helps catch obviously unnatural repetition. Scroll down to paste your content and check its keyword density now.

Frequently asked questions
What is a good keyword density percentage?
A commonly cited healthy range is 1-3%, though there's no official Google standard - natural, readable usage matters more than hitting an exact number.
Can too high a keyword density hurt rankings?
Yes, excessive repetition can look like keyword stuffing, which violates Google's spam policies and can trigger a ranking penalty or filter.
Does keyword density still matter with modern SEO algorithms?
It's less important than it once was since Google's language models now assess semantic relevance, but reasonable, natural keyword usage remains a useful signal.
Should I include the keyword in headings as well as body text?
Yes, using your focus keyword naturally in at least one heading and the opening paragraph reinforces topical relevance without needing high density elsewhere.
What's the difference between keyword density and keyword frequency?
Frequency is the raw count of occurrences, while density expresses that count as a percentage of the total word count for context.
Should I optimize for exact-match keywords or variations?
Use natural variations and related terms alongside your primary keyword - this often reads better and matches how search engines assess topical coverage.
How long should my content be before checking density?
Density percentages are more meaningful in content of at least 300-500 words, since very short text can show misleadingly high percentages from a single mention.
