To know whether your content is good or not, I suggest you put it in Yoast plugin. It will tell you whether you are lacking keywords or you have a problem in the synonyms and paraphrase. But if you do not want to purchase it, the other way is to use online keyword density checker tools, just put your content in and check the density of your keyword, if it is between 1-3% your content is quite okay. Well, what do you say about the new Google Ads policies? How much will it affect the SEO industry?
