Definition: Amplification rate is the number of shares a post receives relative to your follower count, showing how often your audience passes your content on to their own networks.
Also called: share rate per follower

Amplification rate = shares ÷ followers × 100Analytics author Avinash Kaushik proposed amplification as one of four social metrics in 2011, alongside conversation, applause and economic value. His version is simply shares per post (retweets on X, shares on Facebook, share clicks on YouTube). Dividing by followers, as most marketers now do, turns it into a rate you can compare across accounts of different sizes.
Use the platform’s own share action: reposts on X, LinkedIn and Bluesky, shares on Facebook, Instagram and TikTok. Sends in direct messages count as shares on some platforms and not on others, so note what you included and use the same rule every month.
Amplification rate divides shares by followers, so it tells you how willing your existing audience is to pass content on. Virality rate divides shares by impressions, so it tells you how share-worthy the post was to everyone who saw it, followers or not.
A LinkedIn Page with 8,000 followers publishes a post that is reposted 48 times. Amplification rate = 48 ÷ 8,000 × 100 = 0.6%.
Virality rate is the percentage of impressions on a post that led to a share, showing how likely people who saw the post were to pass it on.
Engagement rate is the percentage of people who interacted with a post (liked, commented, shared, saved or clicked) out of the people who saw it or follow the account.
Employee advocacy is when a company’s staff share its news, content and their own expertise on their personal social media accounts, so the brand reaches their networks through people those networks already trust.
A social media KPI (key performance indicator) is a metric you have chosen to track against a specific business goal, with a target and a time frame, to show whether your social media work is succeeding.
