Keyword density and why it matters

It's the oldest debate in SEO land: how often should you use your keyword? It used to be simple: "the more, the better". Today, that strategy can ban your website from Google. In this article, we explain what the ideal keyword density is and how to find the balance between findability and readability.

What is Keyword Density?

Keyword density is the percentage that indicates how often a specific keyword appears relative to the total number of words on a page.

The formula is simple: (Number of times keyword / Total number of words) * 100.

The Dangers of "Keyword Stuffing"

In the 2000s, webmasters tried to manipulate Google by stuffing texts with keywords. Sometimes even with white text on a white background. Google responded to this with the Panda and Hummingbird updates.

Nowadays, Google recognizes unnatural language use immediately. If your text reads like a robot, you get ranked as spam.

The "Goldilocks Zone" (1.5% - 2.5%)

Although Google does not communicate an official percentage, data analyses of millions of pages indicate that the ideal density lies between 1% and 2.5%.

• Below 0.5%: Google might not understand what the page is about (Thin Content).
• Above 3.0%: You risk an 'over-optimization penalty'.

Our Page Analyzer tool uses this margin to assess your content.

The Secret: LSI Keywords (Context)

How does Google know if your page is about "Apple" (the fruit) or "Apple" (the company)? By looking at the words around it.

These are LSI (Latent Semantic Indexing) keywords. Instead of repeating your main keyword 20 times, use synonyms and related terms.
