How it is calculated and how to read it
Density = number of occurrences ÷ total number of words × 100. Words are counted without regard to upper or lower case, URLs are removed, and phrases do not cross sentence boundaries. Common words such as the, of, and, “yang” and “dari” are filtered from the list, and a phrase may not start or end with a common word, but it may contain one in the middle (“jasa dan pembuatan”).
Google does not set an ideal density; chasing a specific figure such as 1–2% is an old myth. Use this tool to make sure your main topic appears naturally, reads well and is not repeated excessively. Repetition above about 3% often reads awkwardly and risks being seen as keyword stuffing.
