Worked Example: Analyzing On-Page Keyword Density
Suppose you have drafted an 800-word article targeting the primary phrase "local keyword research".
With 12 occurrences across 800 words, the density is 1.50%. This demonstrates natural distribution without robotic repetition. The supporting 2-word phrases ("search intent", "service keywords") reinforce topical depth and entity relationships.
Frequently Asked Questions
What is ideal keyword density for SEO in 2026?▾
There is no universal "ideal" keyword density percentage. In modern search engine algorithms, topical relevance and entity coverage matter far more than reaching an arbitrary 2% or 3% density metric. Natural writing that answers user search intent typically results in a primary keyword density between 1% and 2.5%, alongside synonyms and related entities.
What is keyword stuffing and why is it dangerous?▾
Keyword stuffing is the practice of unnaturally repeating the same target phrase across a page to manipulate search rankings. Google systems detect repetitive phrase patterns and can devalue or demote pages that degrade user readability.
How does this keyword density checker calculate phrase frequencies?▾
The tool normalizes text, strips special characters, calculates total word count, and builds frequency distributions for 1-word terms, 2-word n-grams, and 3-word phrases. You can optionally filter out common English stop words (the, of, and) to focus on topical semantic terms.
