In a nutshell: What is WDF*IDF?
WDF*IDF describes the occurrence of a search term and the associated related terms on a page or in a content text. At the same time, the relationship to other pages that also rank with the search term is created and compared.
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 determination much easier. In addition, WDF*IDF is also possible with a calculation 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. Here you can see the relevance of the content.
IDF performs the following task
This area, on the other hand, determines the weighting of a particular word (keyword) in a document for the search engine indexing is. For this, IDF takes the search term and compares it to the entire text.

What is the importance of WDF*IDF for SEO?
As already mentioned, WDF*IDF examines a keyword on the best-ranking pages in Google and analyzes how often it occurs there. Afterwards, a comparison is made with the 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.
So the goal is to create a healthy average of keywords and topic-like terms. This is the only way to make the content more interesting for Google and possibly rank better.
WDF*IDF is used regularly by SEOs and is used exclusively for ONPAGE OPTIMIZATION use. Already now, there have been proven positive ranking effects in trials and optimization tests after a WDF*IDF analysis with corresponding subsequent optimization was performed.

How does WDF*IDF work?
As already mentioned, there is a calculation formula to determine WDF*IDF. But in the daily SEO work, the calculations would take up unnecessary time. 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.
Directly afterwards, the corresponding results are displayed, together with possible suggestions for improvement. Now SEOs and webmasters can get to work implementing corresponding suggestions and carrying out optimizations.
