WDF*IDF Analyse (en)

**Create content with the TF*IDF tool that also ranks in Google**

TF*IDF is a tool often used in search engine optimization to calculate the relevance of your own content in relation to the content of other websites and blogs. WDF stands for "Within Document Frequency" and measures the frequency of all words that appear in a text and categorizes them according to relevance. This refers to the relevance of the content. IDF means "Inverse Document Frequency". This value is used to describe the significance of a word in the document for search engine indexing. For this purpose, the term is put in relation to an overall corpus.

This means that the formula of TF*IDF or a WDF*IDF analysis can be used to determine the ratio in which certain words within a text document, document corpus or website are considered in relation to all potentially possible documents. Accordingly, this formula takes term frequency into account and can be used for OnPage optimization to increase the relevance of a website for search engines without keyword density alone playing a role.

With the WDF*IDF analysis (powered by Seobility) within neuroflash, you can identify important words/terms that are highly relevant for the search engine ranking for certain keywords.

Practical applications for WDF*IDF analysis:

1. Research of important terms/keywords for a topic/search query

In order to get a good overview of possible words and terms, the WDF*IDF analysis is suitable for two purposes. On the one hand, the analysis of the keywords with the highest average WDF*IDF values helps to identify which terms are used by most websites to describe the topic. On the other hand, based on the terms with the highest WDF*IDF values in absolute terms, it is possible to identify the unique selling points of certain pages and thus their most important keywords. Together, this forms a detailed research basis, e.g. for content creation or optimization of an existing page.

2. Competition analysis with the SERP analysis

The WDF*IDF analysis is perfect for taking a closer look at the (well-ranking) content of the competition. If you are wondering what exactly makes the difference between the competitor's page and your website or want to find out why the competitor ranks better, you should analyze the corresponding keywords and results of the competitor in more detail. This information can help you to align and optimize your own content accordingly.

3. Optimization of new or existing texts

Besides the pure topic and keyword research, you can use the WDF*IDF tool directly to optimize your own content. Enter the URL of your website next to the keyword and check the values of your page for the respective terms. Of course, you do not have to mention all terms or have a high WDF*IDF value for all terms. Concentrate mainly on the important terms and check which topics and keywords would be useful, but that your content does not cover yet or only covers insufficiently. A good optimization value for a keyword is above the average WDF*IDF value calculated over all search results that use the keyword and below the maximum WDF*IDF value for the keyword. A too strong use of a term can be considered as keyword stuffing or spamming, so the maximum value should only be used in individual cases.

In order to make the optimization easier for you, the text editor is available. So you don't have to create or change a page to check the WDF*IDF optimization of your content, but can work your way to the appropriate optimization live.

4. For what kind of content and search terms is the WDF*IDF analysis suitable?

An optimization according to WDF*IDF is not necessarily suitable for every search term. The search results should have one of the following characteristics so that WDF*IDF optimization also makes sense:

Results for the search intention "information"
Special topics and niches (long-tail)
Predominantly "text-heavy" results with longer text content
Search terms that produce similar search results in content ("car" vs "buy car")

The following search queries or search results are less suitable for WDF*IDF optimization:

Very general search terms (examples: news, cars, vouchers).
Search terms on current topics (federal elections, refugee crisis)
Search terms with very strong competition (here, other criteria such as user signals, authority of the website, backlinks, etc. usually play a stronger role)
Search terms that deliver very different types of results
