Keyword Density Checker

Understanding Your Results

Stats cards

After every analysis, four metric cards appear above the results:

• Total Words: the raw word count extracted from the page before any filtering
• Unique Words: the number of distinct tokens after applying your current filter settings
• Sentences: approximate sentence count based on sentence-ending punctuation
• Characters: total character count of the extracted text

Target keyword result

If you entered a target keyword, this result appears immediately below the stats cards. It shows the keyword as a highlighted pill, how many times it appeared, its density percentage, and a health badge:

• Healthy (green) — density is 2% or below, a generally appropriate range
• High (orange) — density is between 2% and 3%; consider reducing usage slightly
• Over-optimized (red) — density exceeds 3%; the keyword may appear unnaturally often

Density color coding

Every row in the keyword tables uses the same color system. Green badges indicate healthy density, orange flags terms getting high, and red signals potential over-optimization. This makes it easy to scan the full table and spot problems without reading each number.

N-gram tabs (1 Word / 2 Words / 3 Words)

Each tab shows a count badge with the total number of unique keywords or phrases found:

• 1 Word — individual keyword frequency; useful for spotting repeated single terms
• 2 Words — two-word phrase frequency; useful for identifying repeated phrases
• 3 Words — three-word phrase frequency; useful for long-tail keyword verification and catching unintentional phrase repetition

Each tab shows a ranked table with the keyword or phrase, its count, its density percentage, and a visual frequency bar.

Visual density bar

The bar next to each keyword is proportional — the widest bar belongs to the most frequent term. It makes relative frequency scannable at a glance without comparing numbers row by row.

Live search

The search bar above the tabs filters keyword results in real time. Type any term to narrow the list across all three tabs simultaneously. A match count appears below the search field. Clearing the search restores the full list.

Show All toggle

Each tab shows the top 20 results by default. If more keywords exist, a Show All button appears at the bottom of the table. Clicking it reveals every keyword. Clicking Show Less collapses the list back to 20. The Show All button is hidden while a search is active.

What Is Keyword Density?

Keyword density is the percentage of times a specific word or phrase appears relative to the total number of words in a piece of content. It is calculated as:

Keyword density = (keyword count ÷ total words) × 100

For example, if a 500-word article contains the word “design” 10 times, its keyword density is 2%.

What is the ideal keyword density?

Most SEO practitioners consider 1% to 2% a reasonable target for a primary keyword. At this range the keyword appears naturally and consistently without dominating the text. There is no universally agreed threshold — the right density depends on the topic, content length, and how naturally the keyword fits the writing.

Why does over-optimization matter?

Densities above 3% often result in text that reads awkwardly. Search engines evaluate content quality partly through signals of natural language use. Forcing a keyword into every other sentence can reduce readability and, in some cases, trigger algorithmic filters associated with keyword stuffing. Write for the reader first and let keyword frequency follow from that.

Use Cases

Auditing a live page before a content update
Enter a page URL to see the current keyword distribution before making edits. Identify which terms are over-represented or missing before rewriting any content.

Checking a published page for over-optimization
If a page is underperforming in search, keyword stuffing may be a contributing factor. Run the URL through the tool to see whether any term is appearing at an unusually high rate.

Verifying a target keyword is present at the right frequency
Enter the page URL, type your target keyword into the Target Keyword field, and confirm it appears at a healthy density. If the result shows zero occurrences, the keyword may be absent from the page or filtered by the current settings.

Analyzing competitor pages
Enter a competitor’s page URL to see which keywords and phrases they use most frequently. The 2-word and 3-word tabs reveal topic patterns and phrase structures that single-word analysis alone would not surface.

Checking phrase-level density on long-form content
Switch to the 2 Words or 3 Words tab to verify that a specific two- or three-word phrase appears at the right frequency across a long article or guide.

SEO auditors reviewing client pages
During an audit, quickly identify keyword distribution problems on key landing pages without manually counting terms. The color-coded results make issues immediately visible.

Helpful Tips

Use the 2-word and 3-word tabs to check for phrase stuffing.
Single-word density can look fine while a specific two-word phrase appears at a very high rate. Check all three tabs and look for any phrase carrying an orange or red badge.

Try adjusting the minimum word length.
The default setting of 3 characters removes short tokens like “it” and “or.” Lowering it to 2 will include more terms. Raising it to 4 or 5 focuses results on substantive, longer keywords.

Toggle stop words off to see the full picture.
Running the analysis with stop words included shows how much of the page is function words versus meaningful content. A very high function-word share can indicate thin content.

Use the search bar to check specific terms quickly.
If you want to check whether a specific word or phrase appears in the results without scrolling the full table, type it into the search bar. Results filter immediately across all tabs.

The tool extracts text from the live page.
The keyword analysis reflects what is currently published at that URL. If you recently updated the page, make sure those changes are live before running the check.

A density of 0% for your target keyword may be a filter issue.
If the target keyword result shows “not found,” check whether the keyword consists of short tokens removed by the minimum word length filter or common words removed by the stop words filter. Adjust the filters and the results update instantly.
