Since one year till now I post on the Facebook page roughly 2 times a week an article.
Yet 2 weeks ago I made some changes in the structure of the posts on my site (it is on WordPress). I changed the perma links structure from domain . com/%post%/ to domain . com/%category%/%post%
and so all my back links from other sites stopped working and therefore my SERP rankings dropped immediately.
Those backlinks that I had access to (like on forums or on some directory sites) I managed to fix, the others I redirected.
So now my question is about the broken backlinks on my facebook page. They are about 100.
What would be the best strategy? Should I delete them and repost them again, because this is what I plan to do. Is there a better way to handle them? Do they affect SEO at all?
