Keyword Density is the frequency with which a keyword or phrase appears on a web page. It is also known as keyword prominence and keyword frequency.

It’s essentially the ratio of words to keywords in a blog post. It’s measured by dividing the number of times a keyword appears on the page by the total number of words (excluding HTML tags).

It is an important SEO factor that can be used to identify over or under-optimized pages.

Why is keyword density important for SEO?

When users are looking for products, services, or content, in general, they’ll google a keyword that describes their intent; expecting that search engines find relevant results.

One of the ways search engines are able to find the right results is by scanning how many times a keyword appears in a blog post. If it appears more often and in semantic clusters, search engines think the article is about that topic. (Although they use way more elaborate algorithms than what I’ve just described)

However, having a keyword density that is too high is an indicator of spam and will downgrade the website. meaning you can’t just repeat keywords over and over again and expect to rank. This is called keyword stuffing. It is a black hat SEO practice that search engines frown upon. The result of keyword stuffing can lead to penalization and even removal from the SERPs.

Difference between Keyword Density and TF-IDF?

TF-IDF is an advanced way of measuring keyword density. It means “Term Frequency and Inverse Document Frequency.”

This formula assesses the frequency of a keyword on specific pages (TF) against the number of times this word appears across multiple pages on your site (IDF). The result helps determine how relevant your keyword is for specific pages.

The formula is simply TF multiplied by IDF.

The goal is to determine how important a specific keyword is across multiple documents.

Variations of the TF-IDF formula are used in data mining, user modeling, and information retrieval. It may also be used by search engines to quantify the relevance of a page’s content to a user’s search query.

How to calculate keyword density?

This is the keyword density formula:

The number of times a keyword is used on your page divided by the total number of words on the page then multiply by 100

For example, if your page has 1,000 words and your keyword “cabinet” appears 30 times. This gives:

30 / 1000 = .03 X 100 = 3%

What is the ideal keyword density in SEO?

There are no set rules for the perfect keyword density.

However, many SEO experts advise a keyword density of about 1-2% and it has been noted that Google and other search engines respond well to around 0.5%.

Do keyword variants contribute to keyword density?

Keyword variants contribute to keyword density. After all, they are words and phrases that are similar, but not identical, to your primary keyword.

For instance, if your website sells outdoor lighting solutions, your primary, high-value keyword for SERPs will be “outdoor lighting”. However, variants like “landscape lighting”, “deck lighting” or “patio lighting”, can help your page rank higher and avoid keyword stuffing in one go.

(You can find relevant keyword variants by searching for your primary keyword, then using the “Related Searches” or “People Also Search For” section at the bottom of Google’s SERP.)
