Frequently Asked Questions
What is the ideal keyword density?
Most SEO experts recommend keeping keyword density between 1-2% for your primary keyword. Higher densities (3%+) may trigger keyword stuffing penalties. Focus on natural writing rather than hitting exact percentages.
What are stop words?
Stop words are common words like "the", "and", "is", "in" that appear frequently in all text. They're typically excluded from keyword analysis because they don't carry significant meaning for SEO purposes.
Why analyze multi-word phrases?
Multi-word phrases (n-grams) often represent long-tail keywords that are valuable for SEO. Phrases like "best running shoes" or "how to lose weight" capture user intent better than single words.
Is keyword density still important for SEO?
While modern search engines use semantic understanding, keyword density remains a useful metric. It helps ensure your content covers the topic adequately without over-optimization. Balance is key.
Is my data secure?
Yes, all text analysis happens directly in your browser. Your content is never sent to any server or stored anywhere. This ensures complete privacy for unpublished content and sensitive materials.
