Master Topical Authority
Keywords are the building blocks of search intent. Our Keyword Density Checker provides a forensic look at your content's vocabulary, identifying the phrases that search engine crawlers use to categorize your page.
Unlike basic word counters, we support N-gram analysis, allowing you to track 2-word and 3-word phrases. This is critical for identifying long-tail keyword opportunities and ensuring your semantic clusters are balanced.
Density Precision
Calculate exact percentages for every word and phrase. Identify "keyword stuffing" before it triggers a search penalty.
Stop Word Filtering
Automatically strip common conjunctions and prepositions to focus on the technical and descriptive keywords that actually matter.
Visual Tag Cloud
Instantly visualize your content's "Topical Weight" with a dynamic word cloud that scales based on frequency.
