About Keyword Density Checker

One of the key factors Google used in ranking websites is keywords. Google knows what your content is all about based on the used keywords in your content. However many SEO gurus advise users to use keywords as many times a possible, sometime stuffing these keywords in their content. An artificially high keyword density can result in unnatural, hard-to-read copy and negative user experience. Shoehorning your desired keywords into every possible sentence won’t help your page rank any higher on Google. This practice, better known as keyword stuffing, is a form of black hat SEO that is frowned upon by search engines.

The Panda update penalized websites with thin content and an unusually high keyword density. It also targeted websites that were blatantly engaged in manipulative tactics like cloaked text. The panda updates also brought about the keyword density metric which has been embedded in search engine optimization best practices since the very beginning. Keyword density is the number of times - generally represented as a percentage - your focus keyword occurs in your content, compared to the total text on that web page. Now its advisable to not to go beyond a certain percentage of a keyword in your content to prevent keyword stuffing penalty.


How to Calculate Keyword Density

Learning how to calculate keyword density is fairly easy. You simply take the number of times the target keyword appears on a page and divide it by the total number of words on the web page.

Number of times the target keyword appears / Number of words on a web page = Keyword density

For example, if your target keyword is “internet marketing” and the keyword appears eight times in a 400-word post, the keyword or keyphrase density is 2%. If it appears thirty times in a 300-word post, the density rises to 10%. You get the idea.

What Is the Ideal Keyword Density?

So, how many keywords are just enough? How many are too many? And how do you aim for the ideal keyword density that Google and other search engines won't as being "stuffed" with keywords?

Generally speaking, SEO experts prescribe aiming for a specific keyword density - generally between 1% and 3% - for optimal search performance.

While there are no general rules for keyword density beyond always - relevant "don't keyword stuff" advice, many SEO experts recommend using approximately one keyword for each 200 words of copy.

It's also worth remembering the value of keyword variants — words and phrases that are similar, but not identical, to your primary keyword and long tail keywords. You’re also optimizing for the hundreds of related keywords and searches that come with a major keyword. Your first priority should always, always be to create high quality content that offers an amazing user experience.
