Mastering Keyword Density for SEO
Keyword density is a fundamental concept in Search Engine Optimization (SEO). It measures how frequently a specific keyword or phrase appears within a piece of content relative to the total word count. While search engines like Google have evolved beyond simple keyword counting, maintaining a natural balance is crucial for both ranking and readability.
Why N-Grams Matter
This tool analyzes "N-Grams," which are contiguous sequences of words. Analyzing single words is often not enough.
- Unigrams (1 Word): Good for broad topic identification (e.g., "SEO", "Marketing").
- Bigrams (2 Words): Essential for identifying specific concepts (e.g., "Digital Marketing", "Weight Loss").
- Trigrams (3 Words): Vital for long-tail keywords which often have higher conversion intent (e.g., "Best Running Shoes", "How to Bake").
The "Goldilocks" Zone
There is no magic number for keyword density, but most SEO experts suggest a range between 1% and 2% for your primary keyword.
Too Low (< 0.5%): Search engines might struggle to understand what your page is about.
Too High (> 3%): You risk "Keyword Stuffing" penalties. Content becomes repetitive and difficult for humans to read.
