Lisa Fockens Updated by Lisa Fockens

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 deferred after the website's resources. Simply put, this means it doesn’t affect the loading time of your website for your visitors.
  • We delay loading of popup campaign up to the moment they are needed
  • 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.

How to estimate the impact of Wisepops on your loading time

If you think Wisepops is slowing down your website, here’s how you can find out for sure.

Step 1: Open Chrome dev tools (F12)

Step 2: Click on the “Network” tab

Step 3: Filter with "wisepops.com"

Step 4: Load your page

It will give you a good idea of the time and data Wisepops uses.

What can you do to further limit Wisepops’ impact?

We recommend setting a delay on the campaign's trigger. You can also use "On Exit", "On Scroll", or other triggers. This ensures that your campaign doesn't load while the page is still rendering.

You should also refrain from using too many pictures, as they’re usually the heaviest part of a popup.

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.
