For Google, texts and the keywords have a big significance, as they help Google to determine if the content of your website page is relevant to the search query.
Each topic has its own page
It’s important for a good website structure that each topic has its own page. On that page, only that one topic should be discussed—though linking to other pages is of course possible.
With this kind of structure you’ll also help Google identify which topic is discussed on that page.
Each page has its own keywords
Because every page only deals with one topic, every page automatically has its own keywords which are relevant for that topic. So that Google can find these keywords easily, you should put them in various different places in your content.
Google constantly develops itself to better understand how individual words fit together in terms of content and meaning. This means you need to be careful not to use too many keywords.
