As product manager, I want to know the proportion of pageviews coming from 'X' search engine. To do this, I need a referrer column in the table. See T108895
Scope: we only need the top 20 or even 100 referrer domains [and sometimes subdomain], not all possible referrers. Also, this list does not need to be updated frequently.
- Analyze top 1000 including domain and subdomain, and decide on format of output data
- output data:
- top level domain?
- top 1000?
