What is a keyword density calculator?

The Keyword Density Calculator analyses the frequency and percentage of keywords in your content or on any webpage URL. It identifies the top keywords by usage, calculates their density as a percentage of total words, and highlights potential keyword stuffing that could trigger Google penalties.

Keyword density is the ratio of how many times a keyword appears on a page relative to the total word count. While there's no magic percentage, most SEO experts recommend keeping primary keyword density between 1–3%. This tool helps you strike the right balance — enough repetition to signal relevance, not so much that it looks spammy.

Why use a keyword density calculator?

Over-optimised content with unnaturally high keyword density can be penalised by Google's algorithms. Under-optimised content may fail to rank for target terms. This calculator gives you data-driven insight to keep your content in the optimal zone, helping you rank without risking penalties.

What is keyword density?

Keyword density is the percentage of times a keyword appears in a piece of content relative to the total word count. For example, if 'SEO' appears 10 times in a 500-word article, its density is 2%.

What is the ideal keyword density for SEO?

There is no universal ideal, but most SEO professionals target 1–3% for primary keywords. Focus on natural usage and topical relevance rather than hitting a specific number.

Can high keyword density hurt my rankings?

Yes. Excessive keyword repetition (keyword stuffing) is against Google's guidelines and can lead to manual or algorithmic penalties, reducing your search rankings.

Should I count stop words in keyword density?

No. Stop words like 'the', 'and', 'is' should be excluded. This tool automatically filters them out for accurate density calculations.

Does this tool work on any language?

The tool works best with English content. Stop word filtering is optimised for English, but raw frequency counts work for any language.

Each one opens on its own page and works straight away, with no sign-up.
