Hi @casssandre !
This is a free wordpress plugin for Google reviews. Only reviews from this source can be displayed here, but if you need a widget with combined review sources, please conisder subscribing to our website: trustindex.io.
Here you can connect multiple review platforms under one account if you decide to subscribe to one of our packages: https://www.trustindex.io/prices/
Not sure how many URLs you’d connect but here are the limits to each plan:
The Single plan has a limit of 1 domain and you can connect 3 URLs of the same sources (so 3 Googles, 3 Facebooks, etc…)
The Pro plan has a limit of 5 domains and you can connect up to 10 URLs of the same sources per domain.
The Ultimate plan offers 800 domains and max 200 URLs of the same source.
Here is help for the package selection: https://admin.trustindex.io/support/package_pick
