When you add a link or button to your popup it will work as a custom conversion link by default. If you instead need to add a close button all you need to do is to add “spu-close-popup” class attribute to any HTML element you want to act as the closing button.
For example using a url tag it will be like this:
<a href=”#” class=”spu-close-popup”> Close popup</a>And the same if you want to add it to an image:
<img src=”path_to_image.png” class=”spu-close-popup”/>And if you want to add a link that won’t close or convert your popup you need to add: spu-not-close
