About Keyword Density Checker

The Keyword Density Checker is a powerful SEO utility designed to help content creators and marketers optimize their writing. Unlike simple word counters, this tool analyzes the density of phrases (N-grams), allowing you to see which 2-word and 3-word combinations appear most frequently. This is crucial for identifying long-tail keywords and ensuring your content is properly optimized without being spammy.

Frequently Asked Questions

Keyword density is the percentage of times a keyword or phrase appears in a piece of text compared to the total number of words. It is a key metric for SEO to understand how focused your content is on a specific topic.
There is no perfect number, but most SEO experts recommend checking for a density between 1-2% for your primary keyword. Overusing a keyword (stuffing) can negatively impact your rankings.
N-grams are contiguous sequences of N items from a given sample of text. In this tool, 1-grams are single words, 2-grams are two-word phrases (bi-grams), and 3-grams are three-word phrases (tri-grams). Analyzing these helps identify recurring phrases, not just individual words.
Single word frequency often misses the context. For example, 'marketing' might be common, but 'digital marketing strategy' (a 3-gram) gives you a much better idea of the specific topic. This helps in optimizing for long-tail keywords.
