Runs locally. Phrase density is occurrences divided by total word count × 100. This is a descriptive metric, not a Google ranking score.
What is keyword density?
Keyword density estimates how often a selected word or exact phrase appears relative to the total word count. This tool uses occurrences ÷ total words × 100, displays the most frequent terms, and distinguishes one-, two- and three-word phrases. Other tools may use a different denominator for multi-word phrases, so percentages are not always directly comparable.
Why should you check repeated phrases?
Frequency analysis helps editors spot accidental repetition, inconsistent wording and overused product phrases. For a landing page, a repeated phrase might be intentional, but a page that reads like a list of keywords usually serves readers poorly. Frequency alone does not measure relevance, search intent, originality or quality.
What does “Hide all-stopword phrases” mean?
Common English function words such as “the” and “and” can dominate the table. Hiding phrases made entirely of common words makes the table easier to scan while preserving the original total word count. For longer phrases, sequences containing useful words remain eligible.
How to check keyword frequency without over-optimizing
- Paste the actual draft you intend to publish.
- Review single words for repetitive vocabulary or terminology drift.
- Switch to two- and three-word phrases to find repeated expressions.
- Edit for reader clarity; do not chase a fixed density percentage.
This tool uses Unicode-aware word tokenization. Some languages do not separate words with spaces and may require a locale-aware segmenter for accurate results. It is best suited to space-delimited text, especially English. Google's advice is to write helpful, people-first content rather than optimize around an arbitrary keyword-density target; see Google Search Central guidance.
Frequently asked questions
Does a higher keyword density improve ranking?
There is no universal percentage that guarantees ranking. A phrase-frequency table can help editing but does not substitute for answering the searcher's question.
Does this tool upload my content?
No. The text and calculations stay in this browser tab and are not sent to PostChars.
Can I count phrases rather than individual words?
Yes. Select two-word or three-word phrases to inspect repeated sequences of tokens.
