                1. Facebook changes means that it appears that the share card on Facebook no longer builds share cards based on the canonical meta-data field.

                It appears that Facebook isn't crawling through the canonical to the original post at all anymore actually.

              It appears link shortners are working, or at least the ones I've tested, which means the methodologies that Facebook respects have changed.

            Clearly this is related to Facebook API changes at developers.facebook.com/blog/post/2017/06/27/API-Change-Log-Modifying-Link-Previews/

          Hmmm, maybe not, investigating further

        The problem is occurring, but inconsistently. Odd.

      So it appears that if data is provided from the forwarding URL some of that might be used? We can see it has pulled the source's tags...

    But it is using the image URL from my server, not from the original post. Previously that og:image value was filled by the canonical source.

      Oh great, just noticed another change to Facebook's parsing of metadata for share-cards. No more bylines unless you have a FB URL attached.

        See: nytimes.com/2017/06/30/us/mika-brzezinski-trump-tweets.html (No visible byline on the share card) vs nytimes.com/2017/06/13/technology/uber-travis-kalanick-holder-report.html?_r=0 (Byline visible)

          That's pretty awful. It means Facebook no longer respects authorship without a public Facebook page for the author.

            Means Facebook will only show bylines of people willing to run a page, be spammed, abused, and non-anonymous.

              This is basically Facebook imposing it's real name policy on the entire web. And we all know the multitude of problems that policy has.

                This also means that Facebook is moving away from supporting the rel=author field, which most other social platforms have supported.

                  Not great. I was hoping that we'd see authorship and People schemas create a better and more trusted web via bylines medium.com/@aramzs/authorship-value-and-the-medias-lost-profits-dabe7d1726c8

                    Note in the 1st example, where no byline is included on the Facebook share, the Schema and OG setup for authorship is flawless, just not FB

                      So once again we're moving away from reliably showing bylines in a standard way across multiple platforms. Bad news for journalism.

                        No doubt Facebook would claim this move is part of effort to eliminate fake news. Bullshit. Fake news can create author pages like anyone.

                          Facebook reversed handling of the canonical data, sharing from a forwarding site that lists the target URL as canonical is respected again.

                            This fast a change, seems likely the change in behavior was a bug, not a feature, of the changes to the API for share cards.
