Yoast SEO: the #1 WordPress SEO plugin
Optimize for keywords, keyphrases, synonyms, related keywords, and all word forms of those
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.
