What Is Keyword Extraction?
Keyword extraction is the process of automatically identifying the most important and frequently used words and phrases in a text. It helps you understand the core topics and themes of any content without reading every word.
For SEO, keyword extraction is invaluable. You can analyze your own content to ensure you are emphasizing the right terms, or extract keywords from competitor pages to discover their content strategy. It also helps identify keyword stuffing or under-optimization.

Frequently Asked Questions
Keyword extraction is the process of identifying the most important words and phrases in a piece of text. It helps you understand what a document is about and which terms appear most frequently — useful for SEO, content optimization, and competitive analysis.
This tool tokenizes your text, removes common stop words (like 'the', 'and', 'is'), then counts the frequency of single words, 2-word phrases, and 3-word phrases. Results are sorted by frequency and show keyword density as a percentage.
Keyword density is the percentage of times a keyword appears in relation to the total word count. For example, if a keyword appears 5 times in a 500-word text, the density is 1%. While there is no perfect density, aim for natural usage — typically 0.5-2% for primary keywords.
Use extracted keywords to understand what topics your content (or a competitor's content) focuses on. Compare against your target keywords to find gaps, check if you're over-using certain terms, or discover related phrases to include in your content.
