Frequently Asked Questions
Learn more about keyword density and SEO best practices.
Keyword density is the percentage of times a keyword or phrase appears in a piece of content relative to the total number of words. It's calculated as (Number of keyword occurrences / Total word count) × 100. For example, if your keyword appears 10 times in a 1000-word article, the density is 1%.
Most SEO experts recommend a keyword density between 0.5% and 2.5% for optimal results. Going below 0.5% may mean search engines don't recognize your content as relevant, while exceeding 3% can trigger keyword stuffing penalties. The sweet spot is typically around 1-2% for primary keywords.
Keyword stuffing is the practice of excessively repeating keywords in content to manipulate search rankings. Search engines like Google penalize this practice because it degrades the user experience. It can result in lower rankings or even de-indexing. Our tool warns you when keyword density exceeds 3% to help you avoid this pitfall.
Stop words are common words like "the," "is," "at," "which," and "on" that search engines typically ignore when analyzing content. Filtering out stop words gives you a clearer picture of your meaningful keyword usage. Our tool includes 200+ English stop words and lets you toggle this filter on or off.
Bigrams are two-word phrases (e.g., "keyword density") and trigrams are three-word phrases (e.g., "SEO keyword density"). Analyzing n-grams helps you discover important keyword phrases that single-word analysis might miss. Search engines increasingly understand context through multi-word phrases.
Keyword prominence refers to how important a keyword is based on its placement in the content. Keywords appearing in the first 100-200 words, headings, and the first sentence of paragraphs carry more weight with search engines. Our tool checks if your focus keyword appears in the first 100 words for optimal prominence.
Use your focus keyword naturally throughout your content. A good rule of thumb is once in the title, once in the first paragraph, a few times in the body, and once in the conclusion. The exact number depends on content length. For a 1000-word article, aim for 5-15 occurrences (0.5-1.5%) for natural distribution.
