Keyword Density – KD

Updated on: September 18, 2023

Name: Keyword Density

Referred to as: Keyword Density

Category: On Page SEO


Keyword Density refers to the frequency with which a specific keyword or phrase appears within a webpage relative to the total word count. It’s expressed as a percentage. Historically, many believed there was an optimum keyword density that could boost a page’s SEO. However, this concept is outdated, and adhering to a strict keyword density can lead to over-optimization and poor readability. Writing naturally for the audience, rather than algorithms, should always be the priority.

SEO Evolution: As SEO strategies have evolved over time, so too has the understanding and significance of metrics like keyword density. Google’s algorithms, especially after updates like Panda and Hummingbird, emphasize content quality and relevance over arbitrary metrics.

Updated On: 

Keyword density as a significant metric started losing its prominence after 2011, with major Google algorithm updates. The focus shifted to content quality, relevance, and user intent.

Correct Use:

While keywords are essential for indicating content relevance, it’s crucial to ensure:

1. Content is written naturally, prioritizing reader understanding.

2. Keywords are integrated seamlessly without disrupting flow.

3. Over-optimization is avoided to prevent penalization by search engines.

Our take

Blindly chasing an arbitrary keyword density percentage can lead to content that feels forced and is unenjoyable to read. The real magic in SEO content happens when the writer skillfully weaves keywords into engaging, value-driven narratives that resonate with readers and serve their intent.


  • Focus on creating high-quality content that addresses user intent.
  • Integrate keywords naturally, ensuring they align with the content’s context.
  • Regularly update content, keeping it fresh and relevant.


  • Overstuff content with keywords, making it unreadable.
  • Rely solely on outdated SEO metrics.
  • Compromise user experience in the pursuit of perceived SEO advantages.


Think of keywords as the seasoning in a dish. Just the right amount can enhance the flavor, but too much can make it inedible. Always prioritize taste (readability) over a formulaic approach.


Keyword density gained prominence in the early 2000s as search engines began refining their algorithms. Its significance has since waned as SEO strategies have become more sophisticated.

Worked Example

Let’s illustrate what a 5% keyword density looks like using the keyword “chocolate cake.”

“When making a chocolate cake, it’s essential to use the right chocolate cake ingredients. The base of the chocolate cake should be fluffy. A good chocolate cake often has a rich chocolate flavor. If you’re not using the right chocolate for your chocolate cake, it might not taste as a chocolate cake should. Chocolate cake lovers can tell when a chocolate cake lacks that distinct chocolate cake essence.”

The repetitive and unnatural use of “chocolate cake” makes the content hard to read and enjoy. This is not reader-friendly and diminishes user experience.
