Step by step

Choose a layout and match the colours to your site
Copy the embed code
In Elementor: the Elementor editor
Add an HTML widget dragged from the panel and paste the code

Where to put them
Anywhere you can drop an element, including inside columns, tabs and popups. Inline badge layouts fit a narrow column where a carousel will not.
Full-width sections suit carousel and grid layouts; narrow columns suit a badge.
Does Elementor have reviews built in?
No. Elementor has no built-in review system, so reviews come from an embed or a third-party tool.
If your reviews already live on Google or a marketplace, nothing built into a site builder will reach them.
If they do not appear
Elementor containers with a fixed height will clip the widget. Set the container to auto height.
The Elementor troubleshooting page works through the rest in order.
