Frequently Asked Questions

What is keyword density?
Keyword density is the percentage of times a specific word or phrase appears in a text relative to the total word count. For example, if "content marketing" appears 10 times in a 500-word article, its keyword density is 2%.
What is the ideal keyword density for SEO?
Most SEO professionals recommend a keyword density of 0.5–2% for your target keyword. Below 0.5% may signal the topic is not covered thoroughly; above 2–3% risks appearing as keyword stuffing, which Google penalizes. Natural writing is always better than forcing keywords.
How do I check keyword density?
Paste your content into the keyword density analyzer above. You will see the top 20 most frequent words, bigrams, and trigrams with their exact densities. You can also enter a target keyword to see its specific density and whether it appears in the first 100 words.
What are bigrams and trigrams in keyword analysis?
Bigrams are two-word phrases (e.g. "keyword density") and trigrams are three-word phrases (e.g. "keyword density checker"). Analyzing multi-word phrases helps identify important topical clusters and long-tail keyword opportunities in your content.
Is keyword stuffing bad for SEO?
Yes. Keyword stuffing — unnaturally repeating a keyword to manipulate rankings — is a violation of Google's guidelines and can result in ranking penalties. The goal is natural, reader-focused writing where keywords appear in context. A density of 0.5–2% is generally safe.
