The concentration of keywords in an article or even Content- range reflects the frequency of one or more keywords that are optimized for.

Keyword density calculation

For the calculation of the relevant Keyword Density there are countless starting points of the calculation possibility. These go from the simple calculation of the keywords in the text, to the consideration of the respective plural and or singular case. Furthermore, there are also calculations in which the filler words in the text are taken into account.

Example of a simple calculation of keyword density:

To give you an idea, text A has a total length of 300 words 7 times the Keyword X then the calculation would be as follows.

Calculation:
7/300*100 = 2.33% The keyword density for the Keyword X is then 2.33%

How high should the keyword density be in the text?

In my opinion, there are a few things to keep in mind. Of course, first and foremost, that definitely no one knows what kind of keyword density is necessary to be listed under a Keyword to rank in the TOP 10. In the most common cases, the SEO's keep their experience values to themselves, of course.

In terms of keyword concentration, I have found that if a website has a relatively high trust rank, then the keyword density of 1-2% should no longer be exceeded. For websites that are still relatively new and therefore do not yet have many subpages or backlinks, the keyword density should not exceed 2-3%%.

What dangers can arise if keyword density is too high?

In addition to a sophisticated search algorithm, search engines such as Google & Co also have various filters that can be applied when indexing a website if there is a suspicion of manipulation, spam or similar. These filters can, for example, bring sanctions such as the significant deterioration of the ranking. The penalties can even go so far that the affected website is temporarily or permanently removed from the search engine.Index of the respective Search Engine is excluded or banned.

So, be careful my friend.

Nothing will happen with isolated subpages with too high KWD, but do yourself a favor and don't overdo it, otherwise Google's penalty hammer will fly right in your face.
