- openplatypus 3y agoIt is not just that. Having user IP and such a hashing approach you can re-identify past sessions.

- firtoz 3y agoThen you cannot trust the analytics
- thih9 3y agoDo you trust analytics that doesn’t use JS? Or relies on mobile users to scroll the page before counting a hit? It’s all a heuristic and even with high collision hashing, analytics would provide some additional insight.
- rjmunro 3y agoYou can estimate the actual numbers based on the collision rate. Analytics is not about absolute accuracy, it's about measuring differences; things like which pages are most popular, did traffic grow when you ran a PR campaign etc.
