What is a healthy keyword density?

Most SEO practitioners recommend keeping your primary keyword density between 1-3%. Densities above 5% risk being seen as keyword stuffing by search engines.

Is keyword density still a ranking factor in modern SEO?

Not directly — modern search engines focus more on topical relevance and natural language than exact density. Still, extreme repetition can look manipulative and hurt readability and rankings indirectly.

Why does this tool show 1-word, 2-word, and 3-word phrases separately?

Single keywords, short phrases, and longer phrases each behave differently in content. Checking all three helps you catch both individual word overuse and repeated multi-word phrases.

Why are common words like "the" and "and" excluded from single-word results?

Stopwords like these appear frequently in any text and would dominate the results without adding useful SEO insight, so they're automatically filtered out of the single-word tab.

Does this tool store or share the content I paste in?

No. The analysis runs entirely in your browser — your pasted content is not uploaded or stored anywhere.
