What is keyword density?

Keyword density is the percentage of times a keyword or phrase appears on your page compared to the total words on the page. Keywords help determine your page’s relevancy in the search results, so you’ll use those keywords often. Your keyword density can help you understand how often you use key terms, and if you’re overusing them.

Why use a keyword density checker tool?

A keyword density checker tool is valuable to ensure you’re using keywords appropriately on your site.

Previously, Google had no limit on how often you could use a keyword. As a result, companies would stuff their pages with the keyword to try and rank in the search results. This overuse of keywords caused rankings to suffer because the terms overshadowed the content.

Since then, Google updated its algorithm to discourage this black hat SEO technique. Now, if you use keywords too often, it’s called keyword stuffing, and it negatively impacts your site’s ranking in search results.

A keyword density checker tool can help you check and see if you’re using your keyword too often. It will help you determine if you need to re-optimize your page to reduce keyword usage.

On the other hand, you can also use this tool to see if your keyword usage is too low, and you need to use the keyword more.

Keyword density FAQ

When you use a free keyword density checker, you may have some questions about how it works or what to look for with the tool. Here are some common questions about keyword density.

How do you calculate keyword density?

When you’re using a keyword density analysis tool, you may wonder how your tool calculates your density.

The formula for keyword density is simple:

Number of times the keyword appears on the page/number of words on the page x 100 = Keyword density

So, if you wrote a blog post with 2000 words and used your keyword 20 times, it would look like this:


20/2000= 0.01 x 100 = 1%


So, when you use a keyword density checker, this is most likely the formula the tool will use to calculate your density for you.

What is the ideal keyword density?

Another common question people have when using a free keyword density checker is “what is the ideal keyword density?” The keyword checker will spit back a number at you, but what does it mean? How do you know if it’s good or bad?

The truth is, there’s no magic number that you must obtain to have optimal keyword density. When you research keyword density, you’ll find estimates from 0.5% to 2.5%.

Generally, you want to keep your keyword density below 3%. The exact density will vary with each page. It will take some trial and error to find the right density, but if you use a keyword density checker tool and the results come back above 3%, you need to do some work.

How do you fix keyword density?

When you use the keyword density analysis tool, you may find that your keyword density is too high (or even too low). As a result, you may need to re-optimize your pages.

If your keyword density is too high, go through your page and remove instances of your keyword. You may want to manually check your keyword density for the pages you alter to ensure it’s low enough that it doesn’t appear spammy.

If your keyword density is too low, integrate your keyword more on your page. Use it in places like your headings and within your body text to help your page rank for it. Again, you may want to check your density manually to ensure your changes were enough.

Where should I put keywords for maximum impact?

Where you place your keywords has a significant impact on how your site ranks in search results. To get the most out of your keyword placements, place your keywords in the:

  1. Title tag
  2. Meta description
  3. Body text
  4. Headings
  5. URL

These are some key areas that you can put keywords to help you rank in search results.
