Frequency = occurrences ÷ total source words × 100. The denominator includes stop words. Multiword phrases use occurrence counts, not word coverage.
Discovered phrases
| Phrase | Count | Per 100 words |
|---|
No phrases match this view. Add text or change the stop-word filter.
Read the highlighted passages before editing. Keep repeated terms when they make your explanation accurate and clear.
Inspect repetition in context
Select any phrase in the tables to highlight its occurrences.
Overlapping occurrences are counted separately. Overlapping highlights merge. Blank lines separate paragraphs; sentence and line breaks stop multiword matches.
How to check keyword density
1. Paste the main text
Copy your article or page body. Leave out menus, footers, and unrelated widgets.
2. Inspect your phrases
Add target phrases or explore discovered one-word, two-word, and three-word combinations.
3. Review before editing
Select a phrase, read its highlighted context, and decide whether repetition helps or distracts.
What keyword density measures
Keyword density describes how often a word or phrase appears relative to a text’s length. It helps you inspect wording, rather than predict rankings.
Occurrences ÷ total source words × 100
A phrase appearing five times in 500 words has one occurrence per 100 words, shown as 1% in this report.
For a three-word phrase, this percentage still counts occurrences. It does not count all words occupied by the phrase or represent search engine importance.
The word total includes common words such as “the” and “and.” Hiding stop words changes the discovered phrase list, not the denominator.
Find repetition that a whole-article percentage can hide
An article can have a modest overall frequency while repeating the same phrase several times in one paragraph. Local context makes that easier to notice.
Select a phrase to see its matching passages highlighted. The paragraph list shows where that wording is most concentrated.
A short definition may naturally repeat a technical term. A promotional paragraph may repeat a phrase without adding useful detail. Read both before changing them.
The context preview shows up to 20,000 characters near the first match, with at most 200 highlighted ranges. Full-text counts remain unchanged.
Overlapping occurrences count separately. In “very very very,” the phrase “very very” occurs twice. Highlighted ranges merge so the text remains readable.
Understand how phrase matching works
| Situation | Counting behavior |
|---|---|
| AI tools and ai tools | Case differences are ignored. |
| AI, tools | The comma does not stop a phrase match. |
| AI. Tools | The sentence boundary stops the two-word match. |
| An internal hyphen | A hyphenated expression counts as one word. |
| A blank line | Starts a new paragraph for distribution counts. |
| A word absent from the text | Its supplied target count is zero. |
Matching uses Unicode letters and numbers, with common apostrophe and hyphen variants normalized. It does not infer synonyms, plurals, entities, or search intent.
English stop words can be filtered from discovered phrases. For another language, disable that filter. Languages without word spacing need dedicated segmentation.
Avoid editing toward an arbitrary percentage
Use frequency to identify passages worth reviewing. Judge each occurrence by clarity, relevance, and usefulness.
Keep precise terms when readers need them. Remove repeated wording when it makes sentences awkward, distracts from the point, or adds no meaning.
Google’s spam policies address unnatural keyword repetition. Use the highlighted context to make an editorial decision, rather than chasing a universal target.
Keep a useful record of your edits
Counts update as you edit. Inspect the highlighted context to decide which repeated phrases are useful and which need attention.
Download your report before leaving or refreshing the page. Your draft is not saved between visits.
The CSV includes target phrases and discovered phrases with their counts, phrase length, and occurrence rate. The interface shows only the top 50 per length.
Use the export to compare editorial revisions. It records text frequency, not a forecast of traffic or search performance.
Connect frequency checks with a reader-focused workflow
Start with the reader task using our Search Intent Checker. Keyword repetition cannot replace a clear purpose or useful evidence.
Review difficult sentences with the Readability Checker and explore our readability guide. Keep important terms accurate while improving flow.
For planning, use the SEO Content Brief Generator. Group research queries with the Keyword Clustering Tool before drafting.
Keyword density checker questions
Is there an ideal keyword density?
This tool does not prescribe a percentage. Use frequency to inspect wording, then judge relevance, accuracy, and readability in context.
Does a high count mean keyword stuffing?
No. A technical topic can naturally repeat a term. Counts alone cannot establish intent, quality, or a search policy violation.
Do I need to create an account?
No. Paste your text to start checking phrases, inspect highlighted matches, and download your report.
How are multiword phrases counted?
Each matching sequence counts once, including overlaps. Occurrences are divided by the total word count. This is not the percentage of words covered.
Does punctuation affect matching?
Case differences and common apostrophe or hyphen variants are normalized. Sentence punctuation and line breaks stop multiword matches. Commas do not stop a match.
What does the stop-word option change?
It hides discovered phrases starting or ending with common English words. It does not change total words or counts for your supplied targets.
Can I check a URL?
This version accepts pasted text only. Copy the article body without menus or footers to keep counts focused on the content you want to edit.
How long can my article be?
You can paste up to 150,000 characters. Analysis uses the full supplied text, without AI sampling. Split longer documents into sections.
Does keyword frequency measure search demand?
No. These counts describe your supplied text. They do not measure search volume, keyword difficulty, rankings, or audience demand.
Which languages work?
Word matching supports Unicode letters and numbers. The stop-word filter is English only. Languages without word spacing need a language-specific segmenter for reliable counts.
