AI Search Insights for Keyword Density

✓

AI engines detect topic authority, not keyword count

AI answer engines use semantic understanding, not keyword matching. They evaluate whether your content genuinely covers a topic with depth. Keyword stuffing that might have worked for old-school SEO actually hurts AI visibility because it signals low-quality content.

⚡

Natural density range: 1-3%

For a target keyword, 1-3% density is the natural range for well-written content. Below 1%, you might not rank for the term. Above 3%, both Google and AI engines may flag over-optimization. Write naturally and check the density after — don't optimize word by word.

ℹ

Related phrases matter more than exact matches

AI engines understand synonyms and related concepts. Instead of repeating "AI visibility" 20 times, use variations: "AI search presence," "AI engine citations," "brand mentions in AI answers." This signals topical depth and reads naturally — both things AI engines reward.

What this keyword density analyzer does

Paste your text or a URL and this free tool counts how often each word and phrase appears, as a percentage of total words — so you can see whether your main keyword is used naturally or stuffed.

How to read keyword density

There's no magic number: aim for natural usage. A main keyword around 1–2% is typical; much higher often reads as stuffing.
Look at phrases, not just words: two- and three-word phrases show how you actually cover a topic.
Cover related terms: modern search rewards topical coverage (synonyms and related concepts), not one repeated keyword.
Write for people first: if a sentence only exists to repeat a keyword, cut it.
