92 What is TF IDF?
Ans. TF*IDF is an information retrieval technique that weighs a term’s frequency (TF) and its inverse document frequency (IDF). In other words, TF will tell you the frequency in which a term will appear on a page and IDF will tell you how often the term appears in a larger dataset. A good example will be the top 10 search results of the keyword. When you know how often the keyword appears on all the top websites, that Google ranks, and how often it appears on your page, you can optimize your page content accordingly.
