About Keyword Density Checker

keyword density

The Keyword Density indicates how often a certain term or the search word/keyword appears in a text or document. It does not necessarily have to be just one word, but can also be several words. In this case we speak of a term. The keyword density is a term from search engine optimization and represents an important key figure for every search engine optimizer.

The keyword density is usually given as a percentage. It indicates how often a certain search word or keyword has been used in a document or text compared to the total number of words. If, for example, a test has 1000 words and the corresponding keyword has been used 30 times, we speak of a keyword density of 3 percent. If the keyword density is extremely high, i.e. if a keyword has been used more frequently than average, search engines such as Google may rate it negatively and penalize it.

The interaction between keyword density and search engines

Search engines like Google prefer high-quality content. There were times when you could set keyword to keyword (very high keyword density) and even achieve success in search results. Since this method can be equated with manipulation, it no longer works today. Nowadays, search engines like Google punish websites that do keyword spamming (keyword stuffing). Keyword spamming occurs when keywords are used at an above-average frequency in content.

If, for example, Google has unmasked a keyword spamming website, Google punishes this by positioning the corresponding website worse in the rankings.

Keyword density value

The perfect value of the keyword density is hard to name. One reason for this is that the opinions of many search engine optimizers differ. The problem is that Google, for example, keeps this value secret and has never disclosed keyword density information in the past. The values one has today are based on experience and determined values of already existing texts with correspondingly good rankings.

However, there is widespread agreement that the ideal keyword density is around 3-5 percent. However, there are also those who say that the ideal keyword density is twice as high. Since Google not only evaluates websites with the help of keyword density, but also includes far more factors (over 200 ranking factors) in the evaluation, reliable conclusions about the ideal keyword density can only be drawn very poorly.

One should not remain mistaken in the belief that the keyword density is the all decisive ranking criterion. Given the fact that Google wants to provide its own users with high-quality and exclusive content, one should primarily make sure that the website content answers the user's question or request. If this is the case, the user experience is usually satisfactory and the user may come back to the website again. No matter how high the keyword density is, it is not a clear indicator of the quality of a text. For example, a text with an above-average keyword density does not necessarily have to be better or worse than a text with a low keyword density.

WDF*IDF analysis is suitable for measuring the quality of a text. This is a process in which documents are set in relation to documents from other websites (e.g. competition websites), compared and then evaluated. This involves checking (with the help of a formula) the relevance of the website in relation to a specific topic. Then it is checked which other websites are relevant to this topic. To put it simply, one tries to find out which conditions are already fulfilled by climbing websites, in order to then adopt them for one's own website if necessary.

Keyword density and search engine optimization

From the point of view of search engine optimization, keyword density is only one of many ranking criteria and nowadays has only a very small significance. Nevertheless, the keyword density can serve as an orientation when writing texts. If, for example, you have written a text and find that the keyword has rarely been used, you can make further additions. However, if the keyword density is particularly high, you can consider replacing individual keywords with synonyms or deleting them altogether.
