Frequently Asked Questions — Keyword Density Checker
What is the ideal keyword density for SEO?
There is no perfect number, but most SEO experts recommend a primary keyword density between 1% and 3%. Going below 1% may not signal relevance strongly enough, while exceeding 3% risks appearing as keyword stuffing which can hurt rankings.
Does Google use keyword density as a ranking factor?
Google does not use a strict keyword density formula. Instead, it uses natural language processing to understand content relevance. However, keywords still need to appear enough times for topical relevance signals. The density checker helps you find a natural balance.
What are n-gram phrases and why do they matter?
N-grams are multi-word phrases. Bigrams are two-word phrases and trigrams are three-word phrases. Analyzing these helps you identify your content themes and ensure important topic phrases appear naturally. Ranking for long-tail keyword phrases often drives valuable traffic.
