Your keyword analysis will appear hereHow to Use the Keyword Density Checker
Check the most frequent single words in pasted text, their counts, and their density in the analyzed word total.
Enter Your Content
Paste your article, blog post, or webpage text into the content box. The tool lowercases the text, removes punctuation and other non-alphanumeric characters, and analyzes only single words that are at least three characters long.
Analyze Keywords
Click 'Analyze Keywords' to see the top 20 words by frequency, plus the total analyzed words and unique-word count. Each density is calculated from the analyzed words, with colour labels for up to 2%, over 2% to 3%, and over 3%.
Optimize Your Content
Use the output as a prompt to review repetition and readability, not as a ranking target. The checker does not analyze phrases, search intent, or keyword placement, so assess those factors separately before editing content.
Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears on a page compared to the total number of words on that page. For example, if a keyword appears 10 times in a 1,000-word article, the keyword density is 1%.
What is the ideal keyword density for SEO?
The ideal keyword density is generally 1-2%. This range signals to search engines that your content is relevant to the keyword without appearing spammy. Density above 3% is considered over-optimization and can hurt your rankings.
Is keyword density still important for SEO?
Yes, but it's less important than it used to be. Modern search engines focus more on semantic relevance, user intent, and content quality. However, maintaining optimal keyword density (1-2%) still helps search engines understand your content's focus.
What happens if keyword density is too high?
If keyword density is too high (3%+), search engines may consider your content as 'keyword stuffing' - a black hat SEO technique. This can result in lower rankings or even penalties. It also makes content less readable for users.
How many words should my content have for accurate analysis?
For accurate keyword density analysis, your content should have at least 300 words. Shorter content may not provide meaningful density data. For blog posts and articles, aim for 1,000+ words for comprehensive coverage.
Should I optimize for one keyword or multiple keywords?
Focus on one primary keyword per page, but also include related secondary keywords and semantic variations. Modern SEO favors comprehensive content that covers a topic thoroughly rather than targeting a single keyword repeatedly.
Does this tool analyze phrases or just single words?
This tool analyzes individual words (single-word keywords). For phrase analysis (2-3 word phrases), you'll need to manually check the density of specific phrases. The tool shows the top 20 most frequent single words in your content.
