Learn more about privacyKeyword density was a ranking factor two decades ago and is now mainly a diagnostic — useful for noticing that you never actually said the thing your page is about, and useless as a target to hit.
What Keyword Density does
Counts word frequency with stop-words excluded, so "the" and "and" do not crowd out anything meaningful.
There is no correct density. Modern search engines work on meaning rather than repetition, and writing to hit a percentage produces the stilted prose that keyword stuffing penalties exist for.
What it is good for
| Counts | Word frequency, stop-words excluded |
|---|---|
| <strong>Target density</strong> | <strong>There is not one</strong> |
| Genuinely useful for | Noticing your topic is never stated plainly |
| Also useful for | Spotting accidental repetition |
| Not useful for | Hitting a percentage |
| Search engines now use | Semantic relevance, not repetition |
| Stuffing | Actively penalised |
| Runs | On your device |
Detailed steps
- Paste the page copy.
- Check the topic actually appears — a surprising number of pages never say it.
- Look for words you have repeated without noticing, and vary them.
Worth knowing
The useful finding is absence, not frequency. Pages written by someone deep in a subject often never state it plainly — an article about compressing video that says "the tool" and "this" throughout and never the phrase itself. Density analysis catches that. Chasing a target percentage does the opposite of helping.
Frequently Asked Questions
What density should I aim for?
None. There is no threshold that helps, and writing toward one produces exactly the unnatural repetition that search engines penalise. Write for the reader and use this to check nothing important went unsaid.
Is keyword density still a ranking factor?
Not meaningfully. Search engines model meaning, synonyms and context rather than counting occurrences. Extreme repetition is still detected — as spam.
What is it actually useful for?
Two things: confirming your page states its topic explicitly somewhere, and catching accidental repetition of a word you leaned on without noticing. Both are editorial, not algorithmic.
Should I use synonyms?
Yes, because people search in different words and because it reads better. That is writing well rather than an SEO technique, which is rather the point.
Is Keyword Density free?
Yes. The Vootkit free plan includes 5 tool runs a day. Upgrade to Vootkit Pro for unlimited daily use, an ad-free workspace and saved workflows.
Are my files uploaded?
No. Keyword Density runs entirely in your browser — your file is processed on your own device and never sent to a server. There is nothing for us to store or delete.
Do I need to install anything?
No. Keyword Density works in any modern browser on desktop, tablet or phone. Open the page and start.
How often can I use it? Is there a daily limit?
On the free plan you get 5 tool runs a day. When you reach the limit you'll see a prompt to upgrade, and it resets the next day. Vootkit Pro removes the cap entirely for unlimited daily use.
