The Google Search Console connector supports aggregating data on property or page level. Aggregating by page will return metrics per canonical URL, while the property aggregation will return metrics per property i.e. site.
As an example, consider the property https://funnel.io. If aggregating by property, any search results including the pages https://funnel.io/about and https://funnel.io/data-sources would be part of the property's statistics. On the other hand, aggregating on page would return separate results for each URL.
Please note that the choice of aggregation level will affect the way certain metrics are calculated. To learn more about the differences between the two and how it affects your metrics, please refer to the Google Support article on the Search Console Performance report: https://support.google.com/webmasters/answer/7576553#urlorsite
