Keyphrase density says a lot about the topic of your text. Search engines like Google are set on serving their users the best possible answer to their search query. To determine whether a text answers to what the searcher is looking for, Google checks several things. To that end, you need to tell Google what your page is about. That is one of the reasons you decide on a focus keyphrase, as it helps you stay focused on the subject. After setting your focus keyphrase, several checks in the Yoast SEO plugin help you keep on track.
These checks help you determine whether your text is optimized for the phrase you want it to be. The keyphrase density indicator checks how often your focus keyphrase is mentioned in your text. Because if a text is about a specific subject, it would be strange if you don’t mention it, or barely do.You need to find the right balance in mentioning your keyphrase enough, but not too much. If you overdo it, Google might see that as keyword stuffing. This is not a tactic they appreciate. So how do you know when enough is enough? By keeping an eye on your keyphrase density score in Yoast SEO, you’ll know to add or remove mentions of your focus keyphrase.
If Google cannot run the mobile-friendly test, our best advice is to use the “Analyze entire site” button, create an account on Ryte (formerly OnPage.org) and see what they have to tell you. It could be that you have a robots.txt file that’s blocking indexation, it could be that your theme has some code in it that’s blocking search engines, etc. etc. Ryte can tell you what the problem is and how to fix it!
