Calculating TF-IDF For Keyword Density

Keyword density is a measure that represents how frequently a keyword appears within a web page’s content, relative to the total word count.

Keyword density is a concept that has evolved with the growth of search engine algorithms. While it is no longer a dominant factor in SEO, understanding and implementing keyword density, including advanced methods like TF-IDF, can contribute to crafting content that balances relevance with readability. The right approach, supported by tools and guided by best practices, can lead to improved rankings and a better user experience.

Definition of Keyword Density

Keyword density is the percentage that a particular keyword or phrase occupies in a web page’s total text. It was once a significant factor in search engine rankings but has since been overshadowed by other more complex measures of relevance.

How to Calculate Keyword Density

The standard formula for calculating keyword density is:

Keyword Density=(Number of times keyword appearsTotal number of words in the text)×100

The Role of Keyword Density in SEO

Relevance Indication

Helps in indicating the relevance of the content to a particular keyword.

Avoiding Spam

Too high a keyword density can be seen as spam by search engines, leading to penalties.

Different Ways to Calculate Keyword Density

Standard Calculation

Using the formula mentioned above, you can calculate the keyword density by dividing the number of times the keyword appears by the total word count.

Term Frequency-Inverse Document Frequency (TF-IDF)

TF-IDF is a more sophisticated measure, considering not only the frequency of a keyword in a specific document (Term Frequency) but also how common that keyword is across a collection of documents (Inverse Document Frequency).

Term Frequency (TF)

The number of times a term appears in a document divided by the total number of terms in that document.

Inverse Document Frequency (IDF)

A measure of how common a term is across a set of documents. It’s calculated as:

IDF=log⁡(Total number of documentsNumber of documents containing the term)

TF-IDF: Multiply TF by IDF


This gives a better indication of a keyword’s importance within a specific document relative to a broader context.
