In August, Microsoft announced they will close Bing shopping. Bing replaced it with Product Search, which simply integrates product results within Bing search results rather than in a separate destination.
Today, if you try to go to the Bing Shopping destination, i.e., bing.com/shopping — you are redirected to Bing’s home page.
Bing is using a 301 redirect, so this is a very permanent change.
Merchants who want to be included in Bing Product Search can do so both with paid an organic, non-paid, ways.
