Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a keyword appears in your content relative to the total word count. Formula: (keyword count ÷ total words) × 100. A 1000-word article mentioning "SEO" 15 times has a 1.5% keyword density for that term.
What is the ideal keyword density?
Most SEO professionals target 1–3% for the primary keyword. This tool flags keywords above 3% as "Too High" and those below 0.5% as "Low". A good rule: use your primary keyword naturally and prioritise readability over hitting a specific percentage.
What is keyword stuffing?
Keyword stuffing is the over-use of keywords in a way that reads unnaturally. Google's Panda update specifically targets this. Signs include: repeating the same phrase every other sentence, keyword-filled footers, and invisible text. This tool helps you spot potential stuffing before publishing.
How do I fix a keyword density that's too high?
Replace some exact keyword instances with: synonyms, related LSI keywords, pronouns, or restructured sentences. For example, "free SEO tools" could alternate with "no-cost SEO utilities", "these tools" or "our SEO checker".
