I like photos. I tend to “Like” them, too. But despite my “clicks of approval” (read: we never really know what Likes mean), I don’t always click through to content when a news org shares an image.
Maybe everyone is more systematic than I am, but my Likes are pretty arbitrary. I’m calculated about a lot of things, but my commenting is pretty arbitrary, too.
Two things to healthily recognize here: “Liking” isn’t unvaluable to a news org, and neither is commenting. We can measure some value with those statistics and participate in a “Like science.” At the same time, measurement of engagement on something like Facebook may be inexact when you’re looking at all kinds of journalistic impact. (See good discussion on better measuring journalism’s impact here.)
Putting some of that conversation aside, if your journalistic meat doesn’t lay in Facebook’s garden, my gut is you want your audience to stay awhile on the content on your site. For whatever reason or combination of reasons—financial or philosophical.
If that’s you, here’s a good question worth considering: How do you share visually on Facebook and additionally draw in website traffic?
