Frequently asked questions
What is keyword density?
It is a term’s count divided by the word count, expressed as a percentage. The tool also counts adjacent two-word phrases. It is descriptive text analysis, not a Google ranking score.
What density should I target for Google?
There is no universal target percentage or penalty threshold measured by this tool. Use the counts to spot repetition and write naturally for the reader; a density score does not predict ranking.
What are two-word phrases (bigrams)?
Two-word phrases are pairs of consecutive words, also called bigrams. For example, "search engine", "keyword density", and "content marketing" are two-word phrases. Analyzing these gives you insight into phrase-level keyword usage.
Using the results
Good analysis needs to be both fast and private. The Keyword Density Analyzer processes your text locally and shows results as you work, so you can iterate on drafts and data freely, knowing the content is never transmitted or stored.
