After a conversation with @Gilles, WMF Online Fundraising would like to gather more information about the effect of CentralNotice banners on Google's Web Vital metrics, potential impact on our search rankings, and things we can do to mitigate it.
I'm requesting Google Search Console access for the following domains, and their *.m.wikipedia.org versions, where we run our major fundraising campaigns:
en.wikipedia.org
de.wikipedia.org
es.wikipedia.org
fr.wikipedia.org
it.wikipedia.org
ja.wikipedia.org
nl.wikipedia.org
pt.wikipedia.org
sv.wikipedia.org
Also the following fundraising domain, which I just want to monitor more generally and see if there's any improvements we can make:
donate.wikimedia.org
Thanks!
