Klout

Klout was a social media analytics platform that measured a user's online influence based on their social media activity, engagement, and interactions across various platforms. It assigned a score from 1 to 100, reflecting how much influence a person had within their network. Higher scores indicated greater influence, and Klout provided insights on topics users were most influential in. While it was popular for a time, Klout faced criticism regarding its methodology and relevance, and it discontinued services in 2018, reflecting the complexities of measuring online influence accurately.
