Question

I have a like button on each page in a wallpaper site. There is an option to edit the title of the wallpaper. Hence, the URL of the page changes as well, like it happens in Stack Overflow. In Stack Overflow, when the title of the question changes, the old URL is redirected permanently to the new URL. The same logic is implemented in my site.

The problem is, say if there are 10 likes for a wallpaper page

http://www.example.com/1/old-title-wallpaper

If the title is changed slightly to ‘new title’, the URL changes to

http://www.example.com/1/new-title-wallpaper

In the new page, the like count becomes 0. Is there a way to make the Like button detect 301 redirection.

Answer 1

The like button uses the og:url tag. On your new page you need to keep the old og:url value.
