Three routes, depending on whether the reviews already exist somewhere else, live in your store, or do not exist yet.
How to add reviews to Weebly
The exact steps for Weebly, in about five minutes, without a developer.
The short answer
Build a widget, copy one line of code, and paste it into your page. No developer and no theme files.
Step by step
Build the widget and connect your review sources
Choose a layout and match the colours to your site
Copy the embed code
In Weebly: open your page editor
Add an HTML block and paste the code
Save and check the live page
Where to put them
An Embed Code element dragged onto the page.
Full-width sections suit carousel and grid layouts; narrow columns suit a badge.
Does Weebly have reviews built in?
No. Weebly 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
Check the code is on the page and that changes were published rather than previewed.
The Weebly troubleshooting page works through the rest in order.
