The Site Activity Index measures how much of a website's content changes between two consecutive days — from 0% (static) to 100% (a complete overhaul).
Across nearly 2,000 indexed sites the average is around 20% a day, with major Swedish news outlets closer to 30%. The idea is a shared benchmark marketers can use for competitive content analysis. It earned a press feature in Dagens Analys.
