Discrepancies in Google Search Console results

The way Google Search Console aggregates clicks and especially impressions is quite opaque. It is known that aggregation level affects the total counts heavily. These counts are meant to be interpreted as estimations.

Google has their reasons for this kind of aggregation:
- Privacy. Some queries are filtered out because they contain identifiable information.
- Technical differences between tools. We are using the Search Console API which processes data differently from the Search Console UI.
- Computation time. To get an estimate quickly, Google changes the sampling algorithm based on what dimensions you split the data with.

- "Why do I lose data when asking for more detail?" under https://developers.google.com/webmaster-tools/search-console-api-original/v3/how-tos/all-your-data

Please note that this is a feature of the Search Console products only. Other Supermetrics connectors, including for example Google Ads connector, should be perfectly in line with data from native UIs.
