Keyword density is a metric that measures the percentage of times a keyword appears on a page compared to the total number of words on that page.
With the help of useful plugins such as Rank Math, you can automatically track a piece of content’s keyword density directly from your WordPress page editor.
This article will show you how to find and understand your keyword density score using the Rank Math plugin.
How to Find Rank Math Keyword Density Score
- To get started, login to your WordPress Dashboard, then install and activate the Rank Math plugin.
- After the plugin has been installed, select which existing post or page you would like to optimize.
- On the right of the page, find the Focus Keyword box, then enter your selected keyword* or keywords.
*For the sake of this exercise, we will only be using a single keyword.
- Once you have done that, Rank Math will automatically provide keyword density feedback under the Additional section.
Understanding Rank Math Keyword Density Score
Rank Math’s keyword density test checks how many times your focus keyword(s) and their combinations have been used in the post. The plugin checks for both the primary focus keyword and secondary focus keywords to provide you with your keyword density score.
Rank Math uses icons to help you understand your score. The keyword density score may display partially filled icons depending on the percentage of the score acquired out of the total score assigned to that test.
Below is what each icon means:
- Filled green check mark: Passed
- Filed red X: Failed
- Unfiled green checkmark: 50-99% of the total score
- Unfilled yellow checkmark: 31-49% of the total score
- Unfilled red checkmark: 1-30% of the total score
Although there is not an optimal keyword density score when it comes to SEO, to get the highest score on your keyword density test, you will need to keep your keyword density between 1-1.5%.
If you exceed a keyword density of 2.5% (known as keyword stuffing), Rank Math will give you a warning that you are overusing your keyword(s).
Of note, the plugin’s keyword density test now takes all the variations of the focus keyword into account, meaning you can also type in a keyword’s plural forms, synonyms, etc. If you find that your keyword density score is either too high or too low, try adding or removing the keywords a few times until you get your desired result.
According to Rank Math, a low keyword density is better than a high keyword density, but the most important thing is to make sure you keep the language neutral.
Even if you overuse a keyword and search engines don’t pick it up, it is likely your readers still will.
Congratulations, you should now know how to find and understand your keyword density using the Rank Math SEO WordPress plugin.
