The one thing to know about Framer
Framer is where the design-led crowd went and almost nobody has written review-widget content for it yet. The embed is straightforward; the opportunity is that the page exists at all.
Where reviews belong in a Framer site
An Embed component in the canvas, or site settings for a script that runs everywhere.
Full-width sections suit carousel and grid layouts; sidebars and narrow columns suit a badge. Floating badges can be restricted to particular pages and to desktop or mobile.
Reviews and search results
The widget outputs review schema markup automatically. Whether Google shows a star rating depends on what the reviews are attached to — worth reading before you expect stars, because for a business reviewing itself the answer is usually no.
What does help either way: reviews on the page are content, and a page that answers what customers actually say is a page people stay on.
