What Is Keyword Extractor?

The Keyword Extractor identifies the most important words and phrases in any text by analyzing frequency, position, and context. Unlike simple word counting, it filters stop words, applies minimum length thresholds, and ranks terms by their prominence in the text. This helps you understand what a piece of content is about, identify potential target keywords, and compare topic focus across multiple pieces of content.

Technical Guide

Keyword extraction uses frequency analysis combined with stop word filtering and term weighting. The algorithm counts word occurrences, removes common English stop words, applies minimum length filtering, and sorts by frequency. For multi-word extraction, it identifies bigrams and trigrams that appear multiple times. Position-based weighting can be applied — terms appearing in the first and last paragraphs are often more topically relevant. The tool processes text entirely client-side using JavaScript string operations and regular expressions.
