How it works
A transparent view of repeated language.
Counts and percentages describe the current draft. You decide whether repetition is useful terminology, ordinary language, or copy that needs revision.
- 01
Add your page copy
Paste an article, landing page, product description, or another draft. Words and phrase positions are counted locally as you type.
- 02
Explore the language
Switch between single words, two-word phrases, and three-word phrases. Include common words, change the minimum length, or filter the table.
- 03
Review and export
Track one exact phrase, spot omissions or awkward repetition, then copy or download the current density table as CSV.
Deeper phrase analysis
Useful frequency data without a fake ranking formula.
Focused review controls
Exclude common English words, set a meaningful minimum word length, search the result table, and track a separate exact target phrase.
Private, portable results
Drafts remain in local browser storage, analysis never leaves the device, and the visible result set can be copied or downloaded as CSV.
Keyword density questions
Calculations, phrases, SEO myths, and privacy.
What is keyword density?+
Keyword density is the number of times a word or phrase occurs divided by the number of possible word or phrase positions in the text, expressed as a percentage. Toolkit always shows the raw count beside the percentage.
What is the ideal keyword density for SEO?+
There is no universal ideal percentage. Google has explicitly said it has no notion of optimal keyword density. Use frequency analysis to confirm clear terminology and notice unnatural repetition, not to chase a ranking formula.
How are two-word and three-word phrases counted?+
Toolkit examines each adjacent phrase position, including overlapping phrases. A two-word phrase in a 100-word draft has 99 possible positions; a three-word phrase has 98.
What happens when common words are excluded?+
Single stop words such as “the” and “and” are hidden. Multi-word phrases remain available when they contain at least one meaningful word, preserving natural phrases instead of breaking the original word order.
Does a repeated phrase mean keyword stuffing?+
Not automatically. Brand names, product terminology, and the main subject can repeat naturally. Keyword stuffing is repetition or listing intended to manipulate rankings that sounds unnatural or appears out of context. Human review remains essential.
Is my content uploaded or retained?+
No. The text is analyzed in your browser. The current draft and settings can be saved in local browser storage, but nothing is uploaded to Toolkit.
