Will the JavaScript tracker tag break down or slow down my site?

No! Here are some principles behind our JavaScript serving infrastructure and the code itself.

  • Our code is compressed and minified. Both at the JavaScript minification level and at the gzip level (by our servers).
  • We serve from global servers. As detailed in our Servers and Infrastructure page, Parse.ly JavaScript is served using a global DNS provider and a global CDN provider with edge locations scattered all over the United States and even across Europe, Asia, and South America.
  • We use an async approach. Our code loading system is specifically built to async-load the biggest asset after the page has already downloaded, parsed, and executed other assets. This is described in our Tracker technical document.
Thanks, we will be in contact shortly.
