- Read the density, the tables, and the stuffing sibling if flags appear.
Worked example
The sample repeats “keyword density.” The focus box should show a few hits and a density well above 2%. Rewrite until the phrase looks like a heading, not a chorus.
Frequently asked questions
- What density is safe?
- Natural pages often sit around 1–2% for a focus term. This is a count, not a Google API or a ranking promise.
- Do you fetch my URL?
- No. Paste the copy. Nothing is uploaded.
- How is reading time computed?
- Words ÷ 200. That is a common silent-reading estimate, not speech.
- Stopwords?
- Common words are ignored in the density table so they do not drown the focus term. The focus box still counts the phrase you type.
- Is this AI?
- No. Token counts only.
