The tool shows the WDF, the keyword density based on words, the keyword density based on characters and the total frequency of the keywords on the analyzed page.

WDF: keyword density with an extra twist to get better results

WDF is the abbreviation for “Within-Document Frequency”. The WDF value tries to determine the most relevant words of a text. In contrast to the keyword density, the WDF is not calculated through a simple rule of three.

The WDF formula contains two logarithms that make sure that the value cannot be manipulated by over-using the keyword on a page.

The WDF formula is:

In this formula, i is the keyword, j is the page, L is the total number of words on the page and Frequ(i,j) is the frequency of the keyword on the page.

This looks complicated but it’s rather easy. Think of WDF as some kind of ‘normalized’ keyword density value with an extra filter to get better results. The higher the WDF, the more relevant is a keyword. The maximum WDF is 1.00.

Note that there is no perfect WDF value that a keyword should have. The different WDF values help you to compare the relevancy of different keywords on a page.
