How do you decide what earns a spot in the primary nav vs the footer?

The primary nav holds the few destinations most users need to reach their goals, and the footer holds the secondary, legal, and reference links people seek out deliberately, so the test is how central a destination is to the main task. The nav is for the journey almost every visitor is on; the footer is for the long tail they go looking for only when they need it. That single question, is this on the path of the core task or off to the side of it, sorts nearly every link, and it answers far more reliably than guessing what feels important.
The reasoning is that the primary nav is the scarcest, most valuable space on the site, and its value comes from restraint. A short, focused nav lets users find the few things that move them toward their goal at a glance; a crowded one makes every item harder to find, so adding links to the nav for prominence quietly weakens the prominence of everything already there. The footer carries no such cost. It is the place users have learned to scroll to for the supporting cast, the policies, the company background, the help center, the social links, so putting deliberate-seek items there is not demotion, it is correct placement. Centrality to the task is the dividing line because it tracks the difference between what users need on the way and what they go and fetch.
A storefront makes the sort concrete. The primary nav carries Shop, Categories, Search, Cart, and Account, the destinations a shopper touches to actually buy something. The footer carries Shipping Policy, Returns, Privacy, Terms, About Us, Careers, and Contact, the links a shopper consults only at a specific moment, after a problem or out of curiosity, and knows to find at the bottom. Nobody hunting for a return policy expects it in the top bar, and nobody mid-purchase wants Careers competing with Cart for their attention. Each link sits where its role puts it, and the task stays clean.
This flips when centrality is judged per site, not by a fixed list, so the same kind of link can belong in either place depending on the business. Contact lives in the footer for a retailer but earns the nav for a local service business whose whole goal is getting people to call. A blog might promote its newsletter signup into the nav because subscriptions are the core action. The rule is to read centrality against this site’s main task, which means some footer-typical links graduate to the nav when they are the task, and some nav-typical links drop to the footer when they are not. A useful gut check is to imagine the one action you most want a visitor to take, then keep the nav to the destinations on the way to it; anything that fails that test is a footer link wearing a nav costume.
When you decide, list every candidate link and ask whether it sits on the path of the core task most users came to do. If it does, it earns the primary nav, and keep that set short so each item stays findable. If it is secondary, legal, or something people seek only on purpose, send it to the footer where they already know to look. Reserve the nav for task-central destinations and let the footer carry the rest, rather than crowding the nav to make links feel weighty.
