In the eyes of the search engines, all articles are not the same. You might find an article written in a very ordinary fashion but ranks much higher than the one written flawlessly. This is because the search engines don’t really look at the intelligibility of presentation or smoothness of expression, they look at keyword density. What is all this about? Let’s start with understanding keyword density. It can simply be described as the ratio of the keyword being searched on by users on the search engines query boxes in relation to the total number of words in your article.
A keyword is simply a word or a phrase that an individual keys in on the search engine query box when conducting a search online. If for example one of your target audiences searches for ‘organic manure’, and you have a 600 word article on organic produce and manure, it is imperative that you use the keyword ‘organic manure’ at least 4 times, i.e. 1.3% throughout the article, so that the article gets top rankings on the search engine.
Now you might be thinking that if all it takes for an article to rank high is using the keywords at least 4-6 times in the article, you can then go ahead and scatter the article with the keywords haphazardly. No, that is not how it is done. It used to happen years ago where internet marketers used the keywords they are customizing their websites for haphazardly throughout their articles and web pages but not today. Those days, web masters had even devised ways to use as many keywords as possible where they made them invisible to the human eye but visible to the search engine crawlers. This is however not the case today because due to advancement in technology, it has become very hard to trick the search engines.
Today, the search engines prefer a keyword density of 1-4%, anything more than that is considered keyword spamming or stuffing and you risk getting banned by the search engines. There is a formula used today to measure keyword density i.e. (NKR x NWP/TKN) x 100 where NKR stands for the number of times a word or phrase is used in the article, NWP stands for the actual number of words in a given phrase (e.g. in the phrase organic manure’ the NWP =2), and TKN stands for the total number of words in a given article or webpage. Therefore, an article of 600 words that mentions the keyword organic manure twice will end up with a keyword density of .6% while an article that mentions the keyword four times would have a keyword density of 1.3%.
If however your article requires you to mention the keyword at a higher percentage than the recommended 1-3 per cent ratio, you shouldn’t worry of keyword spamming as the search engines today go further to look at theme related keyword techniques to interpret the main aim of the content of your article. If your keywords are relevant and consistent with the theme of the webpage or article, it will be taken into consideration when ranking. While keyword density is not the major determining factor when ranking an article, a webpage or even a description in a free SEO Link Directory, it is still an important factor that should not be ignored.
