What exactly is TF-IDF for SEO?

TF acronym for: Term Frequency

In a word, the term frequency is the occasions a word or expression appears in your content. Periodically advertisers attempt to follow SEO best practices identified with the occasions they often put a keyword in the content, normally no less than at least four. Assuming you needed to expound on a high-protein diet, and the keyword “plant-based protein” seemed four times, then, at that point, your term frequency would be four.

TF = (Number of times a term appears in the piece of content) / (Total number of terms in the piece of content)

For example, let’s assume that the term “seo agency” in a document of 100 words shows 12 times. 

Your TF would be = 12/100=  0.12

IDF acronym for: Inverse Document Frequency

Simply put, the inverse document frequency lowers the value of highly common words while increasing the value of unique phrases and lesser-used terms.

IDF = log_e(Total number of documents / Number of documents with term in it)

Let’s put the second part of this formula to use. Say that from 1,000,000 results, some are mentioning “seo agency” and the number count is 409,000 times.

Now let’s solve the problem:

IDF(SEO agency) = log_e(1,000,000/ 409,000 with term SEO agency in it)= 0.38

TF*IDF = Term Frequency times Inverse Document Frequency= 0.12 * 0.38= 0.046

Then you have also a result of your own TF*IDF. For the word “seo agency”, you have 0.017 while your competitor’s average is 0.046, which is greater than you.

The data indicates that the term ‘seo agency’ is a common denominator in content that is ranking highly in the SERP.
