What is Keyword Density in SEO?
Keyword density is the percentage of times a specific word or phrase appears in a text in relation to the total number of words. This analysis is fundamental for SEO optimization, as it helps maintain a natural balance in keyword usage without falling into over-optimization.
Why is Analyzing Word Density Important?
A word density analyzer allows you to identify if you're using your target keywords with the appropriate frequency. Search engines like Google analyze content relevance based, in part, on the frequency and distribution of keywords.
Best Practices for Keyword Density:
- Optimal density: Between 1-3% for main keywords
- Natural distribution: Words should appear organically
- Variations: Include synonyms and related words
- Context: Words should make sense in context
- Avoid over-optimization: Don't exceed 5% density
How to Interpret Analysis Results
Our analyzer shows absolute frequency (number of appearances) and relative density (percentage) of each word. It also provides the positions where each term appears, allowing you to evaluate if the distribution is natural throughout the text.
Words with higher density are not always the most important. It's crucial to consider semantic relevance and user search intent. A good density analysis should be complemented with keyword research and competitor analysis.
Tips to Optimize Word Density
To improve your content based on density analysis:
- Identify keywords with very low or very high density
- Adjust content to achieve optimal densities
- Include variations and synonyms naturally
- Review that distribution is uniform in the text
- Maintain readability and content quality
