Paste your content, enter your keyword, and get density percentage, frequency count, and word count in under a second. No waiting, no limits.
Get clear, actionable feedback based on your density level — whether it's too low, optimal, approaching stuffing territory, or over the line.
For multi-word phrases, see both the exact phrase density and individual word frequencies. Understand how each component contributes to your optimization.
A color-coded bar shows exactly where your density falls — from blue (too low) to green (optimal) to amber (warning) to red (stuffing detected).

For most content, 1-2% is considered optimal. A 500-word article with 5-10 keyword mentions falls in this range. However, there's no universal "perfect" density — Google prioritizes natural, readable content over exact percentages. Use this tool as a guideline, not a rigid rulebook. Densities below 0.5% may be too low for search engines to understand your topic; densities above 3-4% risk keyword stuffing penalties.
The formula is simple: (Number of times the keyword appears ÷ Total word count) × 100. For example, if "SEO tips" appears 8 times in a 1,000-word article, the density is (8 ÷ 1,000) × 100 = 0.8%. Our tool does this calculation instantly for single words, multi-word phrases, and individual word components — so you don't have to count manually.
Yes. Google's algorithms — particularly the Panda update and helpful content system — are designed to detect and penalize unnatural keyword repetition. Content with density above 4% is at clear risk. Even at 3-4%, readability suffers, which increases bounce rates and reduces time on page — both negative engagement signals. Write for humans first, then use this checker to verify you're in the safe range.
Yes. Enter any phrase — from "SEO" to "best keyword density checker for content optimization" — and the tool calculates exact-phrase density plus individual word frequencies. This helps you understand not just whether your exact target phrase appears enough, but whether the component words are naturally distributed throughout your content.
