Question

I have an article on my site that has published in a wrong category. I wanted to change the category, and since the category name is part of the url, I than added a 301 redirection to the updated url.
That article had also several likes, but after the 301, it was reset to 0 likes, since to Facebook this is now as a new url with no likes.
If I remove the 301 than the likes count is updated again.
Is there a way to notify FB that a certain url is a result of a 301 that has likes count?
I assume it is relevant as well for pages with FB comments

Answer 1

You would need to set the “href” or “data-href” property of the like button to the original url that had the like counts, depending on which like button you are using. Facebook will not follow redirects.
