Keyword Density Checker

Counts words in pasted text and lists the most frequent one-, two-, and three-word phrases. An optional focus word or phrase shows its exact count and occurrences per 100 words.

Paste article or page text, enter an optional focus phrase, and switch between phrase lengths. Results update while you type; Reset clears the text and selection.

For "SEO tools improve SEO results", there are five words. The focus phrase "SEO" occurs twice, or 40 occurrences per 100 words.

Words use Unicode letters and numbers, so accented and Turkish characters remain part of words. Adjacent exact words form phrases; overlapping matches count. Common words for the selected site language are omitted from the single-word ranking, but remain in the total and can appear in a focus phrase. Each frequency is the count divided by the total word count, multiplied by 100.

Use the one-, two-, and three-word tabs to compare repeated wording. Each tab lists at most 15 phrases, sorted by frequency; tied phrases are sorted alphabetically.

This is exact text matching, not stemming or semantic analysis. Punctuation separates words, and the small language-specific stop-word lists are editorial filters. There is no ideal density percentage that guarantees ranking; use the counts to spot repetition and edit for clarity.
