In RepU, open your widget, choose light or dark and left or right, then click Copy next to the embed snippet. You will paste it into the chat in the next step.
In Lovable, open your project. Paste this into the chat, then paste your code underneath:Add this script to index.html, just before the closing </body> tag, so it loads on every page. Do not change anything else.
Click Publish, then Update for later changes, then open your live site to see your Google reviews.
Check your live site in a private window, not the editor or preview. A domain-locked widget only shows on your own domain.
Ask Lovable where it added the script. It should sit in index.html just before the closing body tag, with your data-repu code intact. Later AI edits can remove it.
