Why This Matters for SEO

Keyword density helps you understand whether your content is properly optimized for target terms. Too low and search engines may not associate your page with the keyword; too high and you risk a keyword stuffing penalty. Analyzing n-grams (bigrams and trigrams) also reveals natural phrase patterns that can improve your content's topical relevance and semantic depth.

Frequently Asked Questions

What is the ideal keyword density?+
Most SEO experts recommend a keyword density of 1–2% for your primary keyword. More important than hitting a specific number is ensuring keywords appear naturally throughout the content.
What are n-grams?+
N-grams are sequences of N words. Unigrams are single words, bigrams are two-word phrases, and trigrams are three-word phrases. Analyzing them reveals which phrases dominate your content.
Can keyword stuffing hurt rankings?+
Yes. Google's algorithms detect unnatural keyword repetition and may penalize pages that appear to be keyword-stuffed. Write for readers first, then check density as a sanity check.
