Let’s dug up further!

What is TF-IDF SEO?

TF-IDF is an acronym for term frequency-inverse document frequency, it is used to calculate the importance of the word/phrase in the document. The TF-IDF score will show how you’re using a word rarely or often in a document. It holds value in SEO.

TF-IDF can be utilized in two different ways

  1. It is used to optimize the content for better ranking with TF-IDF score.
  2. In addition to that, it finds out what word or a phrase is used widely by all the website consistently to describe the topic.

How TF-IDF is Calculated?

TF-IDF can be calculated as follow:

wi,j=tfi,j x log(N/dfi)

tfij = number of occurrance of i in j

dfi = number of documents containing i

N = total number of documents

TF-IDF equation is composed of two metrics – Term Frequency and Inverse document frequency.

The Term frequency denotes that the number of time a term appears on a page by dividing it with number word in a document.

TF = 1 + log(Keyword count) / log(total word count of document)

The inverse document frequency is calculated by dividing the total number of documents in a set by dividing the number of documents containing the keyword.

IDF = log (1 + Total Documents/ Documents with keyword)
