What is visitorkit.js script?
A single line of code that accumulates all your website and app analytics automatically from the moment it’s inserted into your site header. This means you can go back in time and analyze insights from past customer events that you weren’t even thinking about before.
Once the page is loaded, Visitorkit minimally impacts page performance since it never touches the UI. That means it never triggers a re-render. Plus, Visitorkit never makes any blocking network requests, and the network requests that it does make will never exceed 2kb.
None of our customers have encountered site performance impact from installing Visitorkit’s code. Visitorkit’s script won’t slow down your website. Capturing all event activity without degrading performance is as simple as inserting a single line of code into your site header.
