Keyword density is the percentage of times a specific word or phrase appears in a text relative to the total word count. For example, if a keyword appears 5 times in 500 words, its density is 1%.
What is a good keyword density for SEO?βΌ
The ideal keyword density is typically between 1% and 3%. Going above 3% may be considered keyword stuffing by search engines and could result in penalties.
What is TF-IDF?βΌ
TF-IDF stands for Term Frequency-Inverse Document Frequency. TF measures how often a word appears in a document, while IDF measures how rare the word is. Higher TF-IDF means the word is more important.
How does keyword density affect SEO?βΌ
Search engines use keyword density as one of many ranking signals. Proper keyword usage helps search engines understand your content topic, but over-optimization can trigger spam filters.
Should I analyze single words or phrases?βΌ
Both! Single-word analysis gives broad topic insight, while phrase analysis (2-3 words) is more relevant for SEO since most searches use multi-word queries.
Does this tool support multiple languages?βΌ
Yes, the tool works with any language. For languages without spaces (Chinese, Japanese, Korean), it analyzes individual characters.
Is my text stored anywhere?βΌ
No. All analysis happens in your browser. Your text is never sent to any server.
What is keyword distribution?βΌ
Keyword distribution shows where keywords appear in your text (beginning, middle, end). Good SEO practice suggests distributing keywords naturally throughout the content.
