Frequently Asked Questions

Common questions about Flying Scripts: Delay JavaScript to Improve Site Speed & Performance

Any script that is not crucial for rendering the first view or above fold contents. 3rd party scripts like tracking scripts, chat plugins, etc are ideal.
Any keyword inside your inline script that uniquely identifies that script. For example "fbevents.js" for Facebook Pixel, "gtag" for Google Tag Manager, "customerchat.js" for Facebook Customer Chat plugin.
defer tells browser to download the script when found and execute it when HTML parsing is complete. When you include a script in Flying Scripts, those scripts won't be executed until there is a user interaction.
Events from the user like mouse hover, scroll, keyboard input, touch in mobile device, etc.
Even if there is no user interaction, scripts will be executed after the specified timeout.
