You try to use a single, relevant but different keyword for every page and post you create for your site. You put it in the title and first paragraph and write naturally around it. For example, one of your keywords for an orchid site might be "prune orchids", so for one post the title might be "How to prune orchids" and the first para might contain, "The best way to prune orchids is...". That's it!
