How to Check Keyword Density in Your Content
Analyse keyword frequency and density in any text with our free Keyword Density Checker. Avoid over-optimisation and improve your SEO.
Steps
Paste your content
Copy the text of your article, page, or document and paste it into the input area. For the most accurate SEO analysis, paste the full body content as it will appear on the published page, including headings and subheadings.
Enter your target keyword (optional)
If you have a specific keyword or phrase you are optimising for, type it in the target keyword field. The tool will highlight its occurrences and calculate its specific density. Leave this field empty to see a full frequency analysis of all terms.
Click Analyse
Press Analyse to process the text. The tool tokenises your content, removes common stop words (the, and, is, etc.), and counts the frequency of each meaningful term.
Review keyword density percentages
The results show each significant word or phrase along with its occurrence count and density percentage (occurrences divided by total words, multiplied by 100). Your primary keyword should appear at a density of roughly 1–2%. Higher than 3% risks being flagged as keyword stuffing.
Identify over- and under-optimised terms
Look for terms appearing at unexpectedly high density — these may be keyword-stuffed sections worth editing. Also look for important synonyms and related terms with zero occurrences — adding these improves topical depth and semantic SEO.
Keyword Density vs Keyword Prominence
Keyword density measures how often a keyword appears across an entire piece of content, but it tells you nothing about where the keyword appears. Keyword prominence refers to where in the content the keyword occurs — earlier and more prominent placements carry more weight. A keyword appearing in the H1, in the first paragraph, and in a subheading is far more impactful than the same keyword buried in the final paragraph even if the density percentage is identical. Good SEO combines appropriate density with strategic prominence: lead with your primary keyword in the title and introduction, reinforce it in subheadings and the conclusion, and let it appear naturally throughout the body without forcing it.
How to Interpret a Keyword Density Report
When you run a keyword density check, focus on three questions. First, is your primary target keyword present and at a sensible density (0.5–2%)? If it is absent or at 0.1%, you need to work it into the text more naturally. If it is above 3%, trim some occurrences. Second, are important semantic variants and synonyms present? Modern SEO rewards topical depth, so a page about 'project management software' should also mention 'task management', 'team collaboration', 'project tracking', and related concepts. Third, are any words appearing at unexpectedly high frequency that are not keywords — words like your brand name, a repeated phrase, or a structural word? These can skew the report and may indicate repetitive writing that readers would find dull.
Beyond Density: Content Quality Signals That Matter More
Keyword density is a historical SEO metric that was critically important in the early 2000s when search engines relied heavily on term frequency. Today it is a sanity check rather than an optimisation lever. The signals that matter most to modern search engines are: E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), content depth and comprehensiveness, user engagement signals like time on page and low bounce rate, backlink quality, page speed, and structured data. Use keyword density analysis to avoid obvious over-optimisation mistakes, but invest the majority of your content effort in writing genuinely useful, accurate, well-structured content that answers the reader's full question.
Frequently Asked Questions
There is no single perfect density, but the widely accepted guideline is 1–2% for your primary keyword. Modern SEO is less about hitting a specific percentage and more about using keywords naturally within high-quality content. Google's algorithms now understand semantic relevance, so a well-written page that uses a keyword 0.8% of the time can outrank a page that forces it to 2.5%.
Keyword stuffing means unnaturally repeating a keyword to try to manipulate search rankings. For example, writing 'Buy cheap shoes, we have the cheapest shoes, our shoe prices are the cheapest shoes available' in an attempt to rank for 'cheap shoes'. Google's Panda and Penguin algorithm updates specifically target this practice and can apply manual penalties to pages that exhibit it. A density above 3–4% for a single term is a warning sign.
Check both. Single keywords (also called unigrams) give you a broad picture of topic coverage. Two-word phrases (bigrams) and three-word phrases (trigrams) reveal whether you are using your target long-tail keywords naturally. Most keyword density tools show analysis for all three n-gram lengths simultaneously.
Keyword density analysis typically covers body text only. However, including your target keyword in your H1, one or two subheadings, the meta title, and the meta description carries significant weight beyond simple density. Use this tool to analyse body text and a separate meta tag generator for optimising your on-page metadata.
