Keyword Density Checker counts how often each word or phrase appears in your text and expresses it as a percentage of total words. It helps you identify over- or under-used terms so you can optimize your content for SEO without stuffing keywords.
Keyword density is the percentage of times a keyword appears in a piece of text relative to the total word count. For example, if "SEO" appears 5 times in a 500-word article, its density is 1%.
Most SEO experts recommend keeping primary keyword density between 1% and 3%. Going above this can be seen as keyword stuffing by search engines, which may negatively impact rankings. Focus on natural, reader-friendly writing first.
Stop words are common functional words like "the", "and", "is", "in" that add little SEO value. Filtering them gives a cleaner view of your actual content keywords. Enable the stop words filter for meaningful analysis.
2-gram and 3-gram analysis finds frequently occurring 2- or 3-word phrase combinations (bigrams/trigrams). These often reveal long-tail keywords and natural language patterns that single-word analysis misses.
Modern search engines focus more on topical relevance and natural language than raw density numbers. That said, monitoring keyword frequency helps avoid stuffing and ensures your key terms appear often enough to signal relevance.
This tool analyzes text you paste directly. To analyze a webpage, copy the page content from your browser (or view-source), paste it here, and enable the "Strip HTML tags" option to remove markup before analyzing.
Understanding how often your keywords appear in your content is a fundamental part of on-page SEO. Our Keyword Density Checker processes your text entirely in the browser — no server uploads, no sign-up, no tracking.
After analysis, you get a full breakdown including total word count, character count, sentence count, and unique word count. The results table lists every keyword (or phrase) alongside its occurrence count, density percentage, and a visual bar so you can spot dominant terms at a glance.
Single keywords only tell part of the story. Our 2-gram and 3-gram tabs reveal frequently used phrase combinations that often correspond to valuable long-tail search queries. Switching between tabs lets you audit your content at multiple levels without any extra steps.
Enabling the stop words filter removes common words like articles, prepositions, and conjunctions from the results, leaving only semantically meaningful terms. This gives you a much cleaner picture of your actual keyword usage and avoids noise in the data.
Enter a specific target keyword in the optional field to immediately see its exact count and density highlighted at the top of the results — perfect for verifying your primary term is used at the right frequency before publishing.
