Use this keyword density tool to identify your mistakes so you can make the appropriate corrections.
In a matter of seconds, your results will display and you can see both the count and density starting with the most frequently used words and phrases. (Keyword density is a calculated percentage based on the number of times a word or phrase is used, compared to the overall word count for that page.)
Keep in mind that SEO elements (including keyword density) should always take a backseat to quality on your web page or article. Otherwise, all SEO efforts are in vain because only pages that are interesting, entertaining, informational, or valuable in any other way will maintain a sustainable presence in search engine results.
However, it is just as important to use this keyword density tool and avoid the extreme of over-optimizing or under-optimizing. While there aren't any proven guidelines set forth by Google for keyword density, you should keep your primary keyword(s) between 2 and 3%, and secondary keywords (long tail search phrases) between 1 and 2%.
There are many ways to improve a website's ranking on search engines. One effective way is to use keywords in your content. Once you use the right keyword, your content will be much easier for the readers to find.
Using keywords won't immediately take you success. You have to make sure to choose the right keyword to use. It should be among the most searched words or phrases by your target market for your content to appear once they type it in Google or any other major search engine. Another thing is to make sure to use proper keyword positioning to avoid keyword stuffing that might affect your page in a negative way. One more thing to remember is to choose the right keyword density.
