问题
We're experiencing a problem where Facebook likes are counted individually for http://urlhere.com and https://urlhere.com.
Is there a way to have those counts combine, and just register for the url urlhere.com, regardless of prefix?
回答1:
Point an og:url meta tag on both URLs to one of them (i.e on both HTTP and HTTPS, point the og:url tag to the HTTP version)
回答2:
Facebook for god knows what reason treats these URL as different URLs. If you switch the whole site to https://, which is what people are doing now due to Google's recent announcement, you WILL lose all your like for http:// URL. Facebook will not follow 301 redirect and keep the likes from the http:// URL.
