First, sketch a prototype of your 404 page. You can find inspiration by browsing examples—for instance, check out the
#madeontilda gallery. Next, write your copy and select an image. After that, choose the appropriate blocks from Tilda's Block Library based on your needs. You can also use single-page ready-made templates, such as Tilda's
business templates. If your website already has a header with a navigation menu, you'll automatically have links to your Home Page and other sections/pages.
