Keyphrase Density

[schultyy]

From Yoast:

Keyphrase density is the number of times your focus keyphrase occurs in your copy, compared to the total text of that page. So if you have a text that is 100 words and 5 of those are your focus keyphrase, your keyphrase density is 5%. We used to call it keyword density, but as, nowadays, you’ll likely focus on a phrase instead of a word, we rather call it keyphrase density.

Further explanation:

The keyphrase density check is part of the SEO analysis in Yoast SEO for WordPress. You need to have a keyphrase density between 0.5 and 3% to get a green bullet. You don’t have to keep the exact order of the words in the keyphrase for the plugin to recognize it. However, all the words of the keyphrase need to be in the same sentence. The length of the keyphrase also factors into how we calculate the keyphrase density. If you have a longer keyphrase, for example, it’s better to use it less often.
