Frequently asked questions

What is keyword density?
Keyword density is the percentage of times a keyword appears in a piece of content relative to the total word count. A density of 1% means the keyword appears once for every 100 words.
What is a good keyword density for SEO?
A keyword density of 0.5%–2.5% is generally considered healthy. Below 0.5% may signal the topic is not prominent enough; above 2.5% risks keyword stuffing, which can hurt rankings. Focus on natural writing rather than hitting a specific number.
What are stop words and should I hide them?
Stop words are common words like 'the', 'and', 'is', 'of' that carry little SEO meaning. Hiding them gives you a cleaner view of your meaningful keywords. Keep them visible if you want a complete word frequency analysis.
Does keyword density include multi-word phrases?
This tool analyses single-word frequency. For multi-word phrases (e.g. 'cloud computing'), use the Target Keyword field — it checks exact phrase occurrences as a proportion of total words.
Does keyword density still matter for SEO in 2024?
Modern search engines care more about topical relevance and semantic context than raw density counts. That said, density analysis is still useful for spotting over-optimisation, finding under-used keywords, and ensuring your primary topic appears enough times to establish relevance.
