Keyword Density Checker — SEO Term Frequency Workspace
generic-text workspace — use word-counter for live word and character statistics
How to Use This Tool
- Paste article draft into the textarea workspace.
- Click Transform — generic-text runs locally with passthrough for this slug.
- Open word-counter in sibling tab for live word and character stats.
- Count target keyword occurrences manually or with editor find.
- Divide keyword count by word-counter word total for density percent.
- Revise copy when density exceeds your style guide threshold.
About This Tool
SEO specialists and content editors measure how often target phrases appear relative to total word count — keyword density — to avoid over-optimization penalties and spot thin content gaps. VSPIC keyword-density-checker maps to generic-text client kind in missing-tools-handlers.generated.ts without a dedicated density algorithm on this slug today.
Transform returns input unchanged because no transformText rules match keyword-density-checker. For live word counts, character totals, line counts, and sentence heuristics that feed manual density math, use word-counter — statistics update on every keystroke entirely in your browser. Divide target phrase occurrences by word-counter word total for approximate density percentage.
Common use cases

Keyword density in modern SEO
Search engines penalize unnatural repetition more than they reward precise density percentages. Editors use density checks as a sanity guard — typically keeping primary phrases in natural ranges while prioritizing readability and entity coverage.
Our page supports the workflow with honest tooling pointers rather than fake automated density scores.
generic-text passthrough for this slug
keyword-density-checker lacks transformText substring rules. Output mirrors input on Transform.
Dedicated density engines would tokenize, lowercase, strip stop words, and compute n-gram frequencies — not implemented on this slug yet.
Use word-counter for denominator statistics
word-counter reports word count, characters with and without spaces, lines, paragraphs, and sentences live. Use word count as density denominator: (keyword occurrences / words) × 100.
Character without spaces helps meta description length checks alongside density review.
Manual keyword occurrence counting
Editor find with match case toggle counts literal phrase instances. Include title, headings, and alt text in separate tallies when auditing full page intent — this textarea covers body paste only.
Relationship to slug-generator
slug-generator builds URL segments from titles. Align primary keyword between title, slug, and body without stuffing — case-converter helps compare heading case variants.
Stemming and synonym caveats
Literal counts treat run and running as distinct unless you normalize manually. Professional SEO tools stem and cluster entities — manual workflow here is approximate.
Client-side privacy for unreleased content
Pre-launch blog and landing copy stays in browser on word-counter and this workspace. No server-side content analysis for generic-text slugs.
Future dedicated density UI
Registry may add keyword list input with highlighted occurrences and density table. Update this page when handler ships.
Thin content detection
Low word count from word-counter plus absent target keywords may signal thin pages — density is one signal among many including backlinks and intent match.
Important notes & limitations
- No automatic keyword frequency table on this slug today.
- generic-text passthrough — no TF-IDF or n-gram analysis.
- Density math is manual using word-counter totals.
- Does not stem plurals or synonyms — literal string counts only.
- Not a replacement for professional SEO audit platforms.
