How does TF IDF work?

The TF*IDF formula provides an overview of terms that other website use wich rank for this keyword in search engines.

It is calculated for every document (i.e. page) and term individually and takes into account how often terms are used with in the documents that rank top in Google to given Keyword. So what you will get back from our tool is a list of Keywords you might want to consider also to use on your page, as long as it fits into your pages context.

With the TF*IDF formula, you can identify in which proportion certain terms within a text document or website are weighted compared to all potentially possible documents. Apart from the keyword density, this formula can be used for OnPage optimisation in order to increase a website’s relevance in search engines.
