What is keyword density?
Keyword density is a combination of the number of times a keyword or a keyword phrase, in proportion with other words, appears on a Web page. For example, if you have a Web page with exactly 100 words on it including all headlines, captions, alt text, and advertising, and you have a keyword phrase that is on the page 3 times, your keyword density is 3%:
Keyword density applies to the page as it displays live on your website. Many people will create content with a high keyword density and then place it on their website with a lot of navigation, images, and advertising content and their actual density will go down.
There is no hard and fast rule for what your keyword density should be. But too little and it won’t be clear to search engines what the page is about and too much and it will look like you’re trying to spam them. Plus, the more times you repeat a keyword phrase the more the page won’t be palatable to your readers.
Don’t let keyword density rule your Web writing. If your page has a very low keyword density, but it’s well written and clear, you’ll get as many readers as you would with a more SEO focused articles.
What should my Keyword Density be?
The accepted sweet spot for keyword density is between 3% and 5%, to get recognized by the search engines and you should never exceed it.
Remember, that this rule applies to every page on your site. It also applies to not just to one keyword but also a set of keywords that relates to a different product or service. The keyword density should always be between 3% and 5%.
So, be sure you have the proper keyword density, because using the correct keyword density will give your site an SEO boost.
