So , Yoast doesn ' t actually change your page . It doesn ' t do anything to give the page better placement in search results . It can only tell you how well your chosen focus keyword is represented in your copy . A green dot doesn ' t mean this page will show up really high on Google , it means you did a good job making sure your focus keyword is in the right places on this page . So your highranking pages are ranking highly for that particular keyword not because of anything you did or didn ' t do , but because there ' s not a lot of competition for that phrase , written exactly that way . Getting a green dot in Yoast won ' t really help you or hurt you . You could change the focus keyword to banana and get a red dot , but it wouldn ' t change how highly your page is ranked for your vape keywords . Yoast is a tool to help you make sure your content is as wellrepresented as it can be and nothing more . As always , it comes down to content . Yoast can help you make sure that good , unique content is properly noticed by Google but in the case of your highranking pages , it was likely already as good as it could get , for a fairly lowcompetition keyword .
