Listeo has option to show 5 latest reviews from Google Reviews for the listings.
To use it, you have to provide Place ID for the listing. If you are using Google Address auto suggestion feature, this will be automatically set if you choose a business/establishment/place from the suggestion list (yes! we have now option to actually search for places, not just address).
Places API allows to show only 5 reviews from that, those results are cached for 48 hours to not generate additional costs for API. To use that feature you need to have API key set for radius search (Listeo Core → Map Options → Google Maps API key for server side geocoding).
Google Reviews are not displaying, what can I do?
If you are sure your API key is configured properly, if it is, the most common reason why reviews are not showing, is because the Place ID you selected is not for the actual place but for it’s address. If you type just the address of place, you get Place ID of that address, but that doesn’t have reviews, you need to get the Place ID of actual point of interest. Example, if you type the address of pizzeria “Via dei Tribunali, 32, 80138 Napoli NA” you get different Place ID then if you type name of the place and it’s address, like ‘Gino e Toto Sorbillo, Via dei Tribunali, 32, 80138 Napoli NA’. You are looking for and ID of that place, that has the reviews.
