SEO Glossary: WDF*IDF

What exactly is WDF*IDF?

 

This is what WDF and IDF mean:

 

• WDF: Within Document Frequency
• IDF: Inverse Document Frequency

 

If SEOs want to determine the WDF*IDF value of their content, appropriate tools are available on the Internet. They make the calculation much easier. However, WDF*IDF can also be calculated using a formula.

 

The bottom line is that WDF*IDF is used to calculate the relevance of your own content. At the same time, it is compared with the content of other websites that also rank at the top of the SERPs. Alternatively, it is also possible to add additional domains to the tools for comparison.

 

WDF performs the following task

 

This area is responsible for categorizing and simultaneously weighting the frequency of all words within a document or page. Above all, it shows how relevant the content is.

 

IDF takes on the following task

 

This area, on the other hand, determines how high the weighting of a certain word (keyword) in a document is for the search engine indexing is. To do this, IDF takes the search term and compares it with the entire text.

 

 

What does WDF*IDF mean for SEO?

As already mentioned, WDF*IDF is used to examine a keyword on the best-ranking pages in Google and analyze how often it appears there. A comparison is then made with your own content in order to compare the results accordingly.

 

WDF*IDF tools then provide tips on how your own content could be enriched with the main keyword and/or other similar terms. The same also works in reverse if a keyword is possibly too highly weighted, i.e. occurs too frequently.

 

The aim is therefore to create a healthy average of keywords and similar terms. This is the only way to make the content more interesting for Google and possibly rank better.

 

WDF*IDF is regularly used by SEOs and is used exclusively for ONPAGE OPTIMIZATION use. Tests and optimization tests have already shown positive ranking effects after a WDF*IDF analysis and subsequent optimization.

 

How does WDF*IDF work?

As already mentioned, there is a calculation formula to determine WDF*IDF. However, the calculations would take up an unnecessary amount of time in day-to-day SEO work. For this reason, some providers and SEO agencies have made it their business to offer helpful WDF*IDF tools on the Internet.

 

Here, users first enter their main keyword for which they want to optimize a text or a main page/subpage. They then enter the target country for the content so that the tool looks around in the corresponding SERPs.

 

Finally, just enter the URL of the corresponding page with the document on which the WDF*IDF analysis is to be carried out.

 

The corresponding results are displayed immediately afterwards, together with possible suggestions for improvement. SEOs and webmasters can now get to work implementing the relevant suggestions and carrying out optimizations.
