You are about to sign off on next year's social plan. The proposal measures success in followers, likes, and comments, and the sales team barely looks at it. Do you keep social as a community-building line item, or hold it to a sales number? The evidence says hold it to sales: a brand's own posts lift sales more than they lift likes and shares, and the content that wins likes is not the content that wins sales. Fund social as a revenue channel, and split the content by which goal you are chasing.
Your brand's own social posts move sales harder than they move likes and shares.
Most teams treat brand-owned social media as a way to build community, with any sales effect assumed to be small and indirect. Pooling the results of 86 studies shows the reverse: sales respond more strongly to extra posts than engagement does (a sales elasticity of about .35, versus about .14 for engagement). That gap is not an impression: the study tests it formally and finds sales respond roughly 2.6 times as strongly as engagement. Social is not only a likes-and-shares channel; budget it as a sales channel too.
Data chart
A brand's own social posts move sales harder than they move likes and shares, so social deserves a sales budget line.
Key takeaway
Your own social posts move sales harder than they move engagement, and the content that wins sales is not the content that wins likes.

Evidence strength: Strong, based on 1,641 owned-social-media results pooled from 86 studies across 31 industries, 14 platforms, and 17 countries (data 2007–2019). These are average sales-and-engagement response patterns, not profit or return-on-investment figures, so they guide where to allocate budget and what to post rather than a direct profit calculation.
