Hello,
Thank you for contacting us and bringing your concern to our attention.
While there is no perfect keyword density, a keyword density of 1-1.5% is sufficient in most cases; the more important thing is to keep your language natural because if search engines don’t pick on the high keyword density, your users definitely will.
In this test, Rank Math checks how many times your focus keyword(s) and their combinations have been used in the post. Rank Math looks for both the primary focus keyword and secondary focus keywords to determine your keyword density.
To get full marks on this test, you’ll have to ensure the keyword density is between 1% and 1.5%.
But a low keyword density is better than a high keyword density. Even with a low keyword density, there is a good chance that Google will pick on your focus keyword. But, a high keyword density is a bad quality signal, which might get you kicked out from the search results.
Since your keyword density is low and if you feel the keywords are appropriate according to you content, you can keep that density.
Hope that helps and please don’t hesitate to let us know if you have any other questions.
