If you’re worried about Wisepops’ impact on your website’s speed, we’ve listed everything you need to know below, from what we’re doing to limit our impact to things you can do on your side to go even further.

What are we doing to make sure Wisepops doesn’t slow down your website?

Our engineers have worked hard to make sure Wisepops loads blazingly fast.

Among other things, here’s what you should know:

  • Our script is loaded asynchronously: it’s not loaded until after all the other elements of the page have been loaded. Simply put, this means it doesn’t affect the loading time of your website for your visitors.

  • We rely on the Google network infrastructure to serve all regions of the world in a few milliseconds.

  • We’re using browser and server cache mechanisms to further improve the loading speed.

  • Our code is optimized and compressed to limit the quantity of data downloaded on your visitor’s device, hence further reducing the loading speed of our script.

  • The Javascript execution time is the time it takes for your browser to render the campaign after having downloaded the network resources. We do our best to make Wisepops fast to render by using lightweight libraries like Preact.

What can you do to further limit Wisepops’ impact?

On mobiles, we recommend you avoid using pictures altogether

On desktops and tablets, you can use services like https://compressjpeg.com/ to compress your pictures and reduce their size.
