What Do Likes, Saves, and Shares Actually Mean?

Likes, saves, and shares tend to get added together and treated as a single "engagement count," but each one actually signals something different. A like reflects a reflexive sense of favorability in the instant someone sees a post, a save reflects a judgment that the content is worth revisiting later, and a share reflects a willingness to recommend the content to others. Among these three, saves and shares tend to be better clues for capturing reactions from audiences closer to purchase consideration—this is the view we've formed through practical experience. If you only look at the simple sum, the "engagement count," this distinction gets buried.

What Exactly Separates Likes, Saves, and Shares?

As we touched on in The Difference Between Reach and Impressions, SNS reports are full of numbers that look similar but carry different meanings. A like is the easiest reaction to give and tends to reflect a momentary sense of favorability as someone scrolls through their timeline, but its correlation with actual brand preference is relatively weak. A save, by contrast, occurs when someone judges that the content is worth revisiting later, even if they don't react to it right away. A share goes a step further still: it involves the social cost of showing the content to one's own followers, making it the highest-hurdle action of the three—and precisely because of that, it reflects a stronger degree of intent.

Why Are Saves and Shares Closer to the Purchase-Consideration Audience?

The act of saving something is often an expression of "I won't decide now, but I want to come back to this later," and this behavior tends to overlap with that of audiences who have begun concretely considering a product or service. The same goes for shares. As discussed in Why High Engagement Rates Don't Always Translate Into Results, a share reflects not simply a quantity of goodwill, but a qualitative judgment that the content is worth passing along to others. That said, this is a general tendency rather than a definitive claim that saves and shares always translate directly into actual purchases for every single post.

Which Metrics Should Be Prioritized as Campaign KPIs?

For campaigns aimed at expanding awareness, it's fine to focus mainly on easy-to-generate metrics like likes and reach. On the other hand, for campaigns aimed at driving branded search or purchases, it's worth separately tracking the trends in save and share counts. As we touched on in Designing KPIs for Influencer Campaigns, KPIs should be combined according to the campaign's objectives, and likes, saves, and shares are no exception.

Even simply tracking these three numbers separately can change the resolution of your campaign reporting. We believe it's worth routinely breaking these figures apart, as a way of picking up on the reactions of audience segments that the combined total alone can't reveal.
