How Keyword Density Analysis Works

We analyze your content across 6 dimensions in milliseconds

Word Frequency

Counts every word occurrence after removing stop words. Shows which terms dominate your content and their exact density percentage.

N-gram Breakdown

Analyzes 1-word, 2-word, and 3-word phrases separately. Multi-word n-grams reveal your actual keyword targeting better than single words.

Target Keyword Check

Enter up to 3 target keywords and see their exact density with a visual meter showing if you are in the optimal 1-3% range.

Over-optimization Warnings

Flags keywords above 3% density (keyword stuffing risk), missing target keywords, and unnatural patterns that could trigger Google penalties.

Frequently Asked Questions

About keyword density and on-page SEO

What is keyword density?

Keyword density is the percentage of times a keyword appears in your content relative to the total word count. If "email marketing" appears 15 times in a 1,000-word article, the density is 1.5%. It helps you ensure you are neither under-using nor over-using your target keywords.

What is the ideal keyword density?

The generally recommended range is 1-3% for your primary keyword. Below 0.5% means you may not be signaling relevance strongly enough. Above 3% risks keyword stuffing penalties. Modern SEO focuses more on semantic relevance and NLP than exact density, but staying in the 1-2.5% range is a safe practice.

Does Google still care about keyword density?

Google does not use a specific keyword density threshold as a ranking factor. However, keyword stuffing (unnaturally high density) is a confirmed negative signal. Using your keyword naturally at a reasonable frequency (1-3%) while focusing on topical depth and semantic variations is the modern best practice.

What are n-grams and why do they matter?

N-grams are sequences of N consecutive words. 1-grams are single words, 2-grams are two-word phrases ("email marketing"), 3-grams are three-word phrases ("email marketing software"). Analyzing 2-grams and 3-grams reveals your actual keyword targeting better than single word counts, because most SEO keywords are multi-word phrases.
