Analysis Report
What is keyword density?
In SEO, keyword density measures how frequently a given keyword or search phrase appears within a piece of text. In the early days of Google, pushing your keyword density aggressively high was a way to rank. Today, algorithms are much smarter and rely on thematic relevance and natural language processing rather than strictly counting exact match keywords.
Ideal keyword density
Most modern SEO guidance suggests keeping your primary keyword density between 0.5% to 1.5%. If you write an 800-word article, you only need to use your main focus keyword about 4 to 12 times. The priority is always natural phrasing and readability.
Why keyword stuffing is bad
- Google Penalties: Google's helpful content updates actively demote pages that read like they were written for search engines rather than human beings.
- Poor UX: Repeating the exact same phrase over and over destroys the flow of your writing, reducing credibility and increasing user bounce rates.
- Loss of LSI opportunities: Instead of repeating the same word 20 times, you could have used 10 different secondary (LSI) keywords to rank for a wider variety of terms.
How to use keywords naturally
- Put your main keyword in the H1, URL, and the first 100 words.
- Use synonyms and related variations throughout the body text instead of repeating the exact phrase.
- Aim to answer user intent completely rather than fixating strictly on the math behind the word count.
