Keyword density plays a very important role in maximizing the search engine traffic for your website. As the world has become so dynamic so Google is also consistently updating its complex algorithm for search to meet the upcoming challenges of time but the importance of keyword density equations ever remain very consistent over the years. It is highly considered in your text and content while deciding the ranking on search engine result page (SERP) as it is very effective on your website.
If your home page is considered to be most important in the area of text and content then just have a look on this example:
The total number of words on the home page of your website is 200 words and the keyword that you want to target is supposed “watches”, it is further assumed that the word “watches” appears four times on your home page. Then your optimal word density calculation will be:
(Keyword appeared / total number of words) * 100 = %
(4 / 200) * 100 = 2%
So the calculated density of your targeted keyword “watches” is 2% and it is actually the best and maximized keyword density for a single word. You don’t need to get worry with mathematical calculations as a number of analyzers and tools are available online which will assist you through a very simple method for its calculation. But its density with 8% or more is definitely indicated as the keyword stuffing by search engine which negatively affects your website and your website could also be penalized for that. It will also adversely affect your website traffic and your website ranking would ultimately be fallen lower in ranking.
