Hi. I'm newby about SEO and I am starting a site with wordpress, but I have some question. 1 - I have some pages that are listing some post. Even if it's just a listing, should I add some content to get +-500 words with my keywords? Inserting a content and then hiding is it a bad practise? 2 - One keyword or multiple keyword per content? 3 - I will write about games and themes. If I am writing a review about the first sonic, should I use my keyword and the name of the game (Multiple keyword then)? Because I wanted that when someone search the name of the game, I want my site appear too. 4 - Is worth to pay for the premium yoast? 5 - Yoast tell me to avoid using the same keyword in different articles, although I have read that we should using the same keyword in various articles to get a better rank. I have also read using the same could be cannibalism, that various content are fighting for the same query. What is the right way? 6 - Backlinks from diferent website languages works?
