Some SEO is done at site level and others at page level. You should certainly populate the page title and the permalink (if you don't want to use the one that's automatically generated), also the page description and meta keywords (preferably some long-tail) - for each page that you want to appear in search results (including the homepage).
There's no guarantee that the major search engines will use your inputs e.g., your page's description or meta keywords - but without something to explain your webpage to them, search engines and potential users are less likely to know that a particular webpage exists.
SEO is a complex and ever-changing skill and much of what you'll read is biased toward business websites trying to capture larger shares of a market but here's a very good guide to the essentials for all kinds of websites:
