In Yoast SEO you can enter the keyword or keyphrase you’d like your post or page to rank for in the search results. We then run a check on your content to check whether you’re using the keywords often enough – but not too often – and in the right spots. In Yoast SEO Premium, we take this one major step further. We will not only check for the keyword or keyphrase you enter, but we will analyze your text on all variations of that word or phrase.
If the keyphrase is “room decorating ideas” and the synonym is “apartment decorating ideas” all the possible word forms of each word are taken into account: ‘apartments’, ‘rooms’, ‘room’s’, ‘decorate’, ‘decorates’, ‘decorated’, ‘idea’, etc. This way, you are truly optimizing your text. With this addition in Yoast SEO Premium, we can guarantee that no other WordPress plugin comes closer to how Google will see your text*!
