TF-IDF stands for frequency-inverse document frequency used to measure the importance of a given keyword on a page. Unlike keyword density, it doesn't just look at the number of times the term is utilized on the page; it moreover analyzes a larger set of pages and tries to determine how vital this or that keyword is.
Say, in car repair, the term "tire repair" is likely to be more vital than "turbocharged engine repair" — essentially because each car has tires, and only a small number of cars have turbo engines. Because of that, the term "tire repair" is progressing to be utilized in a larger set of pages that speak about car repair.
