What is Shared Social Media?

Shared Social Media

Shared Social Media refers to content distributed across social platforms through audience participation - shares, retweets, reposts, user-generated content, employee advocacy, and community reposts - rather than through paid promotion or direct publisher distribution. It’s the “S” in the PESO model (Paid, Earned, Shared, Owned) of marketing channels, and it represents the portion of social reach a brand doesn’t directly control and can’t simply buy.

PESO in one paragraph

The PESO framework, popularised by Gini Dietrich in 2014, categorises marketing channels by how the reach is generated: Paid (ads), Earned (PR coverage, organic press), Shared (social passes through audiences), Owned (the brand’s own properties - site, newsletter, app). Shared sits between earned and owned - more controllable than earned, less reliable than owned - and includes any social distribution driven by audience behaviour rather than ad spend.

What counts as shared social media

Five common forms:

User-generated content (UGC). Customers posting photos, reviews, videos featuring the product. Starbucks, GoPro, and Glossier built large parts of their brand identities on this.

Audience shares of brand content. A brand posts something; followers reshare to their own networks. The multiplier here turns a 10K-follower account into a campaign reaching 100K+ if the content has genuine shareability.

Employee advocacy. Employees posting about the company on their personal feeds. Often more credible than brand-account posts for the same message, because individual voices carry trust brand voices can’t.

Community reposts. Industry communities (subreddits, Slack groups, Discord servers) surfacing brand content to audiences the brand couldn’t reach directly.

Influencer organic posts. Influencer content that isn’t sponsored - genuine enthusiasm shared from their account. Distinct from paid influencer marketing, which sits in the Paid quadrant.

Why shared is structurally different

Three properties that set shared apart from paid and owned:

Trust. A share from a friend, colleague, or trusted community figure carries weight a paid ad never will. The same message, delivered in the same words, is received differently depending on who’s delivering it.

Uncontrollability. Paid reach is predictable: spend $X, reach N people. Shared reach depends on audience willingness to amplify - which is earned, not purchased. A brand can optimise for shareability, but can’t guarantee shares.

Compounding. Each share exposes the content to a new audience that may itself share. Truly shareable content compounds in ways advertising can’t. The tradeoff: most content doesn’t compound, and the brand has to accept that most of its shared-media ambitions won’t materialise.

How to build a shared-media strategy that works

Four disciplines:

Make content genuinely shareable. The reader has to want to pass it on. Shareable content either makes the sharer look smart, funny, or socially valuable, or it provides genuine utility the sharer’s network will appreciate. Generic promotional posts fail both tests.

Invest in community before you need it. Brands with active, engaged communities see 5โ€“20ร— more shares of new content than brands that only post to passive audiences. Community building is upstream of shared-media performance.

Enable employee advocacy. Provide employees with shareable content, context for why sharing matters, and explicit permission. Most employee advocacy programmes fail because the bar to participate is higher than the benefit.

Treat UGC as a partnership, not a raw material. Customers whose content a brand amplifies deserve credit, compensation where appropriate, and a relationship. Extractive UGC programmes - harvest the content, ignore the creator - burn out the source over time.

Measurement in shared media

Shared-media metrics are softer than paid metrics:

Share volume and reach. Standard platform analytics capture this directly for owned-account posts.

Amplification ratio. Shares รท original post reach. A high ratio means each post is multiplying into secondary audiences; a low ratio means posts are landing with the existing followers and stopping there.

Conversation signal. Mentions, comments, DMs, and inbound referrals. Harder to quantify but often more valuable than raw share counts, because conversation indicates depth of engagement.

Attribution of downstream behaviour. Tagging shared-source traffic via UTMs or platform-specific parameters lets marketers trace shared media into funnel outcomes. Attribution is messier than for paid, but it’s possible with discipline.

We built Penfriend to produce content worth sharing - specific, opinionated, useful, well-framed. Shared social media only amplifies content the audience finds worth passing on; generic content generates zero shares regardless of distribution investment.
