Keyword Density Analyzer.

Keyword density is the percentage of times a keyword or phrase appears in a piece of content relative to the total word count. Count of keyword occurrences divided by total words, times 100. A keyword appearing 5 times in a 500-word article is 1% density.

There is no single perfect density. General consensus is 1% to 3% for most content. Below 0.5%, search engines may not associate your page with that keyword. Above 3-4%, you risk triggering keyword stuffing penalties. Focus on writing naturally with keywords in important positions.

Yes, as a useful diagnostic metric. Modern search engines use semantic understanding and NLP to evaluate content relevance, so they do not rely solely on exact-match counts. But density analysis helps identify potential issues like keyword stuffing or insufficient usage.

Stop words are common words like "the," "and," "is," "in," "to" that appear frequently but carry little topical meaning. We filter them from the single-word frequency list. For multi-word phrases, phrases where all words are stop words are filtered; mixed phrases are kept since they often form relevant keyword phrases.

Keyword stuffing is unnaturally repeating a keyword to manipulate rankings. Google penalizes it. To avoid it: write naturally, use synonyms and related terms, keep density below 3%, and read your content aloud. If the keyword usage sounds forced, it probably is.

Both, but multi-word phrases (long-tail keywords) often provide more value. Single keywords are competitive and ambiguous. Two and three-word phrases have clearer intent and are easier to rank for.
