Widget Lazy Load
On every Widget you can find the option on the Advanced Tab
Simply enable it…that’s all!
Set a Placeholder
Define a initial height of the block to simulate the content of the element which will be loaded.
You can set a color or an image as placeholder, like an animated gif that will remain until the element is fully loaded
Increase page speed response time
Lazy load secondary element of the page via ajax only when needed.
This let you obtain a lower time response on page load.
A great and indispensable tool for SEO.
