Collaborative posts (collab posts) on Instagram have emerged as a powerful tool in social media marketing, enabling multiple accounts to co-author and share content simultaneously. This study investigates the impact of collab posts on the overall reach and engagement of the participating accounts, with a particular focus on the reach dynamics of the posts themselves. The study draws on a sample of 100 collab posts from diverse account categories, including athletes, digital creators, companies and community-focused accounts. The findings reveal that while collab posts often achieve greater reach than individual posts, their reach is not merely additive; rather, it aligns more closely with a weighted average of the accounts’ individual reach potentials. The findings indicate that in terms of reach development, only the ‘smaller’ account benefits; by contrast, the ‘larger’ account faces potential disadvantages. The study also highlights the importance of collaboration timing in amplifying visibility. This research contributes to the limited academic discourse on collab posts by offering theoretical insights into the algorithmic mechanisms shaping their reach and providing practical implications for social media marketers. It emphasises strategic considerations such as partner selection, audience alignment and optimal timing to maximise the effectiveness of collab posts in the competitive digital landscape.
