H1_Keyword Density Checker - SEO Keyword Frequency | MultiTool

How it works

Paste your text and type a keyword. The tool counts total words, keyword occurrences and density percentage (with an ideal 0.5-3% indicator), plus a frequency table of the 10 most common words in your text.

Keyword density without the folklore

Ancient SEO folklore claimed a magic density (2%, 3%…) would win rankings. Modern reality is simpler and harsher: there is no magic number. Search engines understand language, not just counts.

• What density is still good for: spotting accidental over-optimization. If your target phrase appears 8% of the time, the text reads robotic — to humans first, and to search engines second.
• The healthy range most editors target: main keyword around 0.5–2%, plus natural variations and synonyms. Write for readers; check the meter only to catch excess.
• Related terms matter more: a page about “air fryer” that never mentions cooking, temperature or crispy is weaker than one that reads naturally on the topic.
• Where keywords genuinely count: title, headings, first paragraph and the URL — one clear appearance each beats twenty repetitions in the body.
