FREQUENTLY ASKED QUESTIONS

Common Questions About Keyword Density Checker

There is no official number — roughly 1–2% for your main keyword reads naturally. The real warning sign is a phrase that towers over everything else.
Paste the text, not the URL — fetch-from-web is blocked by most sites. Copy the article body and analyze that.
