Thank you for your question. We would like to clarify that our subscription does not have a limit on the number of reviews that can be pulled from one specific source.
This source can be a Google location or a Facebook page - we can pull all of the reviews from these sources.
Regarding the Yelp platform, it is more closed if compared with other social media platforms. So currently, their official API does not allow more than 3 reviews to be generated.
That is why we provide Yelp as a free source in our plans.
