Keyword Density Tools enable you to automatically calculate the keyword density of each word and phrase in your content so you can quickly check if you have over-used/under-used any target keywords and search phrases in your content.
Keyword density continues to be one of the most import SEO ranking factors, although it may not be as important as it was a couple of years back. Nevertheless, if your content has low keyword density, it won’t rank well for your target keywords and search phrases. On the other hand, if it has high keyword density, then your website may get penalized for keyword spamming or over optimization. So it’s important to maintain the right keyword density to balance your keywords. Here are 7 Best Free Keyword Density Tools to help you track keyword density and optimize your content to rank better in search engines.
What is keyword density?
Keyword density is the percent of times a keyword occurs in your content. For example, if your target keyword “marketing” occurs 20 times in your web page with 1000 words, then its keyword density is 2% (20 /1000 %). However, if your target keyword “online marketing” occurs 20 times in your web page of 1000 words, then its keyword density is 4% (20 X 2/1000 %). This is because “online marketing” contains 2 words and its each occurrence is counted twice. Here’s the keyword density formula:
Keyword density percentage = no. of times keyword phrase occurs in your content / total number of words in your content
It’s advisable to maintain your keyword density in range of 1-2.5%.
