I'm planning on releasing a number of articles spanning multiple pages. Each page of the article is thematically connected to the other pages through its main topic, but focuses on a particular aspect of this topic. For example, an article on the human body, could have pages focused on the skeleton, the muscles, the vascular system, the nervous system...
Each page would have different title & h1 tags and hence different KWs in the URL.
What is the best SEO practice to tell Google that these pages are all part of the same article (and that, somehow, belong together)?
Note: there are no restrictions as to how the URL or the pages should be built.
