While checking out the Wistia blog, I came across this post that piqued my interest. It resonated with me since I have been taking care of most of our remarketing campaigns lately (sorry if you are inundated with kittens now). I hate how tracking URLs look. Filled with utm_source, utm_campaign and such. Not a clean URL by any standard. However, this is what we need to use to track these campaigns. A necessary evil, I suppose.
What Fresh URL does is delete the tracking code after those tracking services have registered their information. This gives your visitors a nice clean URL if they are moved to share the page. This prevents false page tracking and just makes the internet a nicer place to be.
