The Text Tools formula and how it boosts your search results.


Text Tools is a content optimization app based on a scientific formula known as WDF*IDF (or TF-IDF) that calculates the quality of a body of text – such as on a webpage.

The formula has been used successfully by top SEO’s and marketers in around the globe to increase the relevance of website content, and to make that content more discoverable to search engines.

A lot of people are using Latent Semantic Indexing (LSI),TF-IDF or Google Suggest interchangeably. To analyze the data, we are using a derivate and more accurate Formular of the TF-IDF formular: WDF-IDF. 

The analysis is actually not as innovative as the SEOs worldwide treat the topic. The origins of the analysis go back to the seventies, even though they naturally were not drawn for search engines or other rankings. However the formula and the calculation of terms on which the analysis is based dates back to the seventies.

The WDF-IDF analysis consists of two components:

Within Document Frequency – WDF

WDF describes the term weighting within a document. The term stands for the keyword which appears in a certain frequency in the text. This principle could represent the customary keyword density, however, WDF at the same time operates with a correction value which then allows for a uniform reference to result. In addition WDF is limited by the

Inverse Document Frequency – IDF

This area of the analysis does not only concentrate on one single document but refers the weighting of a certain term in the collection of documents analyzed.

The entire principle is expressed in a formula which will, with the exception of mathematicians, probably confuse many people:
