Display deleted expired ads

Hi, it will be great to have deleted/expired ads on the page
When users post new ads Google indexed them. After the user deletes it or the ads are expired the ads stay in some RSDirectory database so Google still can find them but as expired ads. It will be good for the SEO
It is something like Djclasifides has
