Frequently Asked Questions
What is keyword density?
The percentage of times a keyword appears compared to total word count. If "SEO" appears 5 times in 500 words, density is 1%. It's an important SEO metric.
Is higher density always better?
No! Over 3% looks like "keyword stuffing" to Google and can hurt rankings. Natural, readable content with 1-2% density performs best.
Does this tool check competitor websites?
Paste their content after copying from their pages. For live URL analysis, use our "Meta Tag Analyzer" tool or browser extensions.
What are LSI keywords?
Latent Semantic Indexing keywords are related terms. For "apple", LSI includes "fruit", "orchard", "iPhone", "Mac". Our tool identifies these automatically.
Can I check density before publishing?
Absolutely! That's the best use case. Write your content, check density here, optimize, then publish. Prevention is better than fixing later.
