Tf*idf is a numerical statistic used in information retrieval to represent how important a specific word or phrase is to a given document. TF*IDF Example Consider a document containing 100 words wherein the word SEO appears 3 times. The term frequency (i.e., tf) for SEO is then (3 / 100) = 0.03. Now, assume we have 10 million documents and the word SEO appears in one thousand of these. Then, the inverse document frequency (i.e., idf) is calculated as log(10,000,000 / 1,000) = 4. Thus, the Tf-idf weight is the product of these quantities: 0.03 * 4 = 0.12. Free Tf*idf Tool: https://www.seobility.net/en/tf-idf-keyword-tool/ #SEOFactors #SEO2019 #LSIKeywords #GoogleRank #SERP
