Clarification

Additional Information

Google has highlighted that there can be discrepancies between the charts and the table. But I could not find any information that highlights the discrepancies between two tables (Pages and Countries table).

My understanding is as such:

• The Pages table is aggregated based on the specific page (URL)
• The Countries table is aggregated based on the property (a.k.a. the whole site)

However, unable to wrap my head around:

• Why is there only 51 impressions when aggregating by site?
• But there is 211 impressions when aggregating by page?

Wouldn't each page impression, also translate to a site impression?
