Frequently Asked Questions

What is keyword density?
Keyword density is the percentage of times a keyword or phrase appears in a piece of content relative to the total word count. It's calculated as: (keyword count / total word count) × 100. For example, if your keyword appears 10 times in a 500-word article, the density is 2%.
What's the ideal keyword density for SEO?
There's no single "ideal" density, but most SEO experts recommend keeping primary keywords between 1–3% of total content. Anything over 4–5% may look unnatural and could trigger keyword stuffing penalties. Focus on writing naturally for your audience first, then check density as a sanity check.
What are stop words?
Stop words are extremely common words that search engines typically ignore when processing text — words like "the", "is", "at", "which", "on", "and", "a", "an", "in", etc. Filtering them out helps you focus on the meaningful content words that matter for SEO keyword analysis.
Why should I analyze 2 and 3-word phrases?
Multi-word phrases (long-tail keywords) are often more specific and have less competition than single keywords. Analyzing bigrams and trigrams reveals which key phrases appear most naturally in your content, helping you identify whether you're targeting long-tail terms effectively without repetitive over-optimization.

💡 Target 1-2% density

A keyword density of 1-2% is generally ideal for SEO without risking over-optimization penalties.

💡 Use synonyms

Search engines understand semantic variations — use synonyms and related terms for natural content.

💡 Check for keyword stuffing

If your main keyword appears every 3-4 words, you're likely over-optimized. Rewrite for natural readability.

💡 Focus on user intent

Great content answers user questions naturally. Keyword density is a byproduct of quality writing.

Keyword density analysis helps SEO writers and content marketers optimize articles for search engines without over-optimizing.
