(Filed based on process at https://wikitech.wikimedia.org/wiki/Google_Search_Console_access)
I'm working on a comprehensive review of external re-use of Wikimedia content (T235780). Having access to the Google Search Console will help me understand what data we have from Google on metrics like click-through rate as well as what research questions we could ask of this data.
I see that access is per-domain. I would request English, Spanish, and Indonesian then as a sample to explore:
en.wikipedia.org
en.m.wikipedia.org
es.wikipedia.org
es.m.wikipedia.org
id.wikipedia.org
id.m.wikipedia.org
If you need an expiration date, six months should give me sufficient time.
