Any new product or page that is published is not necessarily linked in the top navigation (depends on your theme). But generally when you create a product, Shopify will generate a URL which you can use anywhere. You can also exclude a product from your Shop All or collections page with a bit of Liquid.
Go to Online Store > Pages.
Click Add page.
Enter a title and content for the page.
Be descriptive and clear when choosing your webpage title. The webpage title displays in the tab or title bar of browsers. It also appears as the page title in search engine results. Learn more about website SEO.
Under Visibility, select when the page should be published. By default, your new webpage will be visible when you click Save. Select the Hidden option if you want your new webpage to be hidden from your online store, or click Set a specific publish date to control when your webpage is published.
Optional: To make a published webpage appear in your online store navigation, add a link to it in a menu.
Unless you intentionally add this page to your online store's navigation menu, it will not show up. Therefore, in other words, once the page is created it will instantly work as you intended it to.

I want to implement similar kindoff thing.
I got your point of creating a hidden page but in my case it would be product page having products which are visible on only that page and not on website as its a sale and offer promotion.
User should be able to add to cart or buy now and checkout similar to normal product page.
How would i add those products and make them visible on this hidden page and not on actual site.
Need urgent help on this
