On average, sites have 43 tags and trackers for analytics and advertising (source: Pingdom research) which increases the page load time by 3x (9 secs with trackers vs 3 secs without trackers).

That's huge! I see developers giving up on fixing this after just making sure that those scripts load at the end. But it can be optimized even more. By using a Customer Data Platform(CDP) such as RudderStack or Segment. These tools provide a way to stream events data from website to various analytics and advertising tools. Which means you load one script of the CDP instead of 43, and then CDP handles the event streaming to those 43 tools. Giving a huge jump in performance improvement as well as the maintenance.

Now this is new for me, wondering if others are doing the same thing already and I was the only one living under rock?
