Q: Hello, Please explain what "WDF*IDF" stands for.
Thank you.

May 14, 2024A: The name WDF stands for "within document frequency" and IDF for "inverse document frequency". The first part of the formula "WDF" calculates the frequency of keyword repetition within our text on a given URL. While the second part IDF calculates the repetition within the competitors' content on the first page of Google for the main term.
We do this for single words, groups of 2 words and groups of 3 words.
With that, we create a graph that allows us:
1- Find subtopics that the top-ranked competitors are addressing and we are not.
2- To find topics that we are dealing with in excess and that the best positioned competitors do not deal with in such depth.
3- Find words that we are using excessively and that may make Google suspect of Keyword Stuffing.
4- Find words that we are using less than we should and improve semantic prominence.
This is a brief summary of what the function allows, but I think it gives you an idea of the range of possibilities it offers. š
Thanks for the reply. So, to understand it doesn't work with long tail keywords? For example, I have a multilingual website, and for Spanish the main goal is to rank on "FUNDAS PARA ASIENTOS DE COCHE A MEDIDA". As you can see here are more than 3 words... (https://seatsstudio.com/fundas-asientos-coche-medida/).
Hello Marcel,
I have explained myself wrong, it does work with long tails, shall we see it with your example?
š With the KW "FUNDAS PARA ASIENTOS DE COCHE A MEDIDA" and your URL, the tool tells me that, in the 1 word group the most important words are:
fundas, asientos, o coche, pero tambiƩn modelo, piel, entrega*, traseras*, peso* o condiciones.
š For the 2 word groups it mentions to me concepts like:
fundas de asiento, fundas a medida*, piel sintƩtica, fabricadas a medida*, gran resistencia*...
š And lastly, for the 3-word groups he talks to me about:
asientos delanteros y traseros, juegos de fundas a medida* o medidas para volkswagen golf
*The KWs that I have marked with an asterisk do not appear in your content or appear very little; they do appear in the content of your rivals positioned on the first page of Google and the tool recommends you to include them.
As you can see, regardless of how long or shot tail the KW is, with the groupings of words we can see what content and what semantics we should expand (or reduce) to improve positioning.
I think now I have explained myself better, but if it is not clear, ask again without fear.
PS1: For groups of 2 or 3 words the system does not take propositions into account.
PS2: I give you the examples in Spanish just as you have done, but it would work exactly the same in any other language š
