When the Keyword Density Checker seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Density looks too high
Rewrite the stuffed passages - modern SEO rewards natural language over thresholds.
Density looks too low
Work the term into headings and early paragraphs where it reads naturally.
Phrase counts look wrong
Variants split the count - include close forms to see the true topic coverage.
Common words top the list
Stopwords dominate raw counts - focus on the meaningful terms, not the and of.
Competitor page results differ from the browser
You compared rendered text against raw HTML - paste the same content into both.
I do not know what target to aim for
Aim for clarity, not a percentage - use the report to spot imbalance, not to hit a quota.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Chasing a magic density number
- Ignoring phrase variants and stems
- Optimising short meta text like a full page
- Forgetting the primary term appears naturally
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
What is a good keyword density?
There is no universal target - density that reads naturally beats any fixed percentage.
Does it count phrase matches?
Yes - multi-word phrases are counted alongside individual terms.
How long can the text be?
Full articles paste in comfortably; very long texts may take a moment to analyse.
Is my text stored?
No - analysis runs in your browser and nothing is saved.
