A social influence score assesses an individual’s impact in a specific field or in relation to a brand. These scores are generally calculated by analyzing an individual’s activity and audience on social media. They are essential for digital monitoring and influence strategies, allowing for better weighting of content based on the publisher’s reputation and improving alert systems.

In the field of monitoring, influence scores help prioritize information based on the credibility of the sources. In influencer marketing, these scores are used to select relevant influencers based on their area of ​​expertise. They also help determine the necessary investment in terms of effort or compensation to collaborate with an influencer.

Influence scores can also be used to create rankings, which are highly valued by media outlets and influencers. They are integrated into social media platforms to facilitate partnerships. There are scores specific to each social network and overall scores that measure influence across all platforms.

To be relevant, these scores must take into account various criteria: the quantitative and qualitative reach of the audience, audience engagement, the individual’s authority, their area of ​​expertise, and so on. However, some challenges remain, such as the difficulty of assessing the influence of blogs and newsletters, detecting fake subscribers, or managing duplicate information.

The most popular influence scores are Klout, PeerIndex (now defunct), and Kred, but any company specializing in influencer marketing or monitoring can create its own composite score. These scores help measure an individual’s impact in an increasingly complex digital world.
