For SEO, content is king. And when content is king, keywords are the link between the article itself and the way search engines read the article you write.
The live keyword density checker is a useful SEO tool that helps you calculate the keyword density of the chosen keywords you have chosen when writing a new article. As a tip, you should choose no more than 3 keywords. Keywords can include more than one word and plurals.
This tool has taken out popular words such as "the", "and" and others so that you can measure the keyword density based on the actual words and not the "connector words".
Please note that for your keyword density to work at its best, it is advised that your chosen keywords have a keyword density of 5-7%.
