Recent research from HubSpot has indicated that Facebook photos generate higher engagement than the average post, and new data provided to MarketingCharts by Socialbakers supports this finding. Socialbakers took a sample of approximately 90,000 posts from 24,000 brand pages around the world during the week of November 26-December 2, and analyzed the top 10% most engaging posts. Of those, 89% were photos, with the remainder being links (4%), videos (4%), and status updates (3%).
Some of that dominance in engagement on the part of Facebook photos is due to their volume. Among that initial sample of 90,000 posts, for example, 77% were photos, with the remainder split among links (9%), status updates (7%), video (6%), and others (1%).
Even when taking that into account, though, photos appear to generate higher-than-average engagement. The HubSpot study, which examined 1,545 B2B and B2C companies in October 2012, found photos generating 53% more likes than the average post (including link, text, and photo posts) and 104% more comments than the average post.
Earlier research from Socialbakers indicates that post types not only see varying engagement rates, but also different levels of organic reach. For that analysis, Socialbakers examined 47,783 from 274 Facebook pages from August through October, finding a general decline in average reach during each month, from 19% in August to 16% in September and 12% in October. (Studies from Group M Next and the Ehrenberg-Bass Institute, as reported by Ad Age, also have found a general decline in post reach, although those studies also found engagement to be rising.)
The decline in reach found by Socialbakers was more pronounced for some post types than others. Links, which boasted the highest level of organic reach in August, at 22%, saw that figure drop to 19% in September and 15% in October. That equates to a 35% drop during that time period.
Photos, which counted as the content type with the second-highest reach in August (19%), saw a drop to 16% in September and 12% in October. In all, a 36% fall over the 3-month period.
Status updates, by contrast, held fairly steady throughout the period, at 16% organic reach in August, 14% in September, and 15% in October. Organic reach for videos, meanwhile, fell from 16% in August to 12% in October.
Overall then, while photos generate above-average engagement on Facebook, they have seen a steady decline in reach, to the point where they trail links and status updates on this measure.
