Frequently Asked Questions
What is keyword density?▼
Keyword density is the percentage of times a word or phrase appears in your content relative to the total word count. It helps SEO writers ensure target keywords appear naturally without over-optimization.
What is the ideal keyword density for SEO?▼
Most SEO experts recommend 1-3% keyword density. Higher than 5% may be flagged as keyword stuffing by search engines. Focus on natural, reader-friendly content rather than targeting a specific percentage.
Does this tool check for keyword stuffing?▼
Yes, the tool highlights words with unusually high frequency. If a word appears more than 5% of the time, it may indicate keyword stuffing, which can negatively impact SEO.
Can I check density for multi-word phrases?▼
Yes! Switch to 'Phrase Mode' to check the density of specific multi-word keyword phrases (e.g., 'digital marketing' or 'keyword density checker').
