Every page or post should focus on ONE 2-3 word phrase. Use that phrase in the title (ideally first if possible). Also use it as one sub-title as a header 2 <h2> and within the data itself. Shorten the post url to that keyword phrase. (That makes it easier to share and use and useful for SEO.)
Knowing what keyword phrase your content is about helps keep your writing focused. It will result in much clearer posts that your readers will understand better.
These two posts are useful to grasp that concept:
