We will share our opinion on how a 404 page should look.
What are the goals of a 404 page?
The goals of the selling site:
- Retain a visitor / client
- Make the client buy a product or service
Therefore, the 404 page should pursue these goals.
What should be shown on a 404 page:
- A cheerful picture, it will smooth out the negative impression that the product was not found.
- Sections, not the "Go to the catalog" button, ideally, but the output of goods.
The trick is to calculate the path that produces a 404 page and display products from the same category where this deleted product originally was.
