WDF (within-document frequency) is a new formula to calculate keyword densities. Based on a special logarithm, it does not yield the relative frequency of a word in the document, but ascertains a condensed value which conveys more information.
The plug-in analyzes one’s own content and creates a list of the 10 most important keywords in the text. In this way unintentional keyword focus can be avoided.
What is innovative about the WDF Buster is the possibility of analyzing competitors on the basis of content, or rather keywords. Within a few seconds the contents of the 10 best placed websites are read in and interpreted.
