Keyword density is a term used in SEO to refer to the number of times keywords are repeated within the copy on a web page. Search engines like Google penalize having a high keyword density because it means that the content is not optimized for the user. But how can you check the keyword density of your web page or blog post?
In this article, we'll go over some keyword density tools that you can use to do so.
The Importance of Keyword Density In SEO
Keywords are one of the most important parts of an SEO strategy, as they help your content rank within SERPs. However, keyword stuffing is penalized by Google and other search engines because it is considered a black hat SEO practice. This means that it’s important to use keywords in the right way.
Although there are no strict rules, a general rule of thumb is that keywords should appear between 1 and 2 times per 100 words. The aim is to create quality content for users.
Knowing the keyword density is important because if you use too many keywords in a short body of text, you will be penalized.
