Frequently Asked Questions
What is the ideal keyword density?
There's no perfect number. Generally, 1-2% for primary keywords is considered natural. Focus on semantic relevance rather than exact percentages. Google uses NLP, not keyword counting.
Does keyword density still matter for SEO?
While less important than in the past, extreme keyword stuffing (above 3-4%) can trigger spam filters. Natural keyword usage with semantic variations performs best.
What is keyword stuffing?
Keyword stuffing is excessively repeating keywords to manipulate rankings. Google penalizes this practice. Modern SEO focuses on natural language, semantic relevance, and covering related entities rather than hitting a specific keyword percentage.
What's the difference between 1-gram, 2-gram, and 3-gram?
A 1-gram is a single word ('SEO'), a 2-gram is two consecutive words ('semantic SEO'), and a 3-gram is three ('semantic SEO strategy'). Analyzing all three reveals both individual keyword density and important phrase patterns.
Can keyword density be too low?
Yes. If your target keyword doesn't appear naturally enough, Google may not associate your page with that topic. Aim for at least 0.5% for your primary keyword, with semantic variations adding natural topical coverage.
How does this tool handle stop words?
Common stop words (the, is, a, an, etc.) are filtered from the analysis by default, so you see only meaningful keyword patterns. You can toggle this filter off if needed.
Should I optimize for exact keyword density?
No. Focus on natural language that covers your topic comprehensively. Google uses NLP (BERT, MUM) to understand meaning, not keyword counting. Use this tool to spot problems like stuffing, not to hit an exact number.
