Recently, I had the opportunity to face a frontend challenge at Configr. It consists of improving the tracking rate of the new users who come to the system (a.k.a. leads). More specifically, the tracking rate from the UTM parameters of the marketing campaigns.
TLDR: I created a javascript library called utmkeeper that do the job for you, and it’s available at https://github.com/humrochagf/utmkeeper. UPDATE (September 21, 2018) Post updated to cover the 0.
