Facebook’s sharer cache

April 22, 2009

Over the past week, we’ve been promoting a series of videos around young adult cancer issues as a way of promoting the launch of our We Get It DVD.

One of the ways we’ve been getting the word out is through Facebook’s Sharer function. If you scroll to the bottom of the page, you can embed some metadata in your page in order to embed a FLV video playable directly within the newsfeed.

This is super cool: based on YouTube’s great Insight tool, approximately 25 per cent of all of the views thus far from this campaign have come from Facebook news feeds of those who’ve posted the video.

On the second day of the campaign, when we posted our second video, I ran into a small problem: I hadn’t updated the metadata, and Facebook seemed to cache the information from the previous day’s video.

After some Googling, I couldn’t find a solution to the issue. So rather than passing the canonical URL for the page to Facebook, I tried passing the 301 redirected page we’ve setup at fyacc.ca for Twitter short URLs.

And, that solved it: Facebook grabbed the updated metadata.
