Here is a link to some of that work done by WMF researchers: https://github.com/wikimedia-research/memo/blob/master/report.pdf
TL;DR: The actual internal referer data did not confirm - in fact, appeared to contradict - those 2015 media reports, which had been extrapolating from indirect data (with IMHO highly speculative conclusions).

Roland, 

We have no internal information on this regard. I think that there is work that has been done on this topic by WMF researchers (Wikipedia's traffic referrals from google) and you are likely to get better pointers asking on list that pinging people individually. Please be so kind as to post your question to analytics@ public e-mail list (analytics@lists.wikimedia.org).

Please have in mind that questions such as this one might not have easy and fast answers so you might get information that is technical in nature.


Thanks,

Nuria

Hey Nuria,

 

Roland Eisenbrand (see below for introduction) would like to know more about how Wikipedias traffic from Google changed (or not) in recent years as a result on new Google services.

Can you please answer or relay?

 

Thanks!

 

Erik

Hello Erik,

 

thank you very much for the reply! I’m very interested in how Wikipedias Google traffic developed. There have been some reports in 2015, that Google is bringing less users to Wikipedia. Some people attributed this development to things like Google Instant Answers and Google Knowledge Graph. I haven’t yet found a statement from Wikipedia if all of this is true or not, so I would love to speak someone from you guys.

 

Best,

 

Roland

Hello Roland,

 

Sorry for delay, I was away for a few days. 

Can you tell me a bit about what kind of questions you have?

Depending on that I might relay your question to Nuria Ruiz Head of WMF Analytics Team.

 

I am still involved on some traffic reports, but mostly on traffic by region, and traffic by wiki.

Nuria and her colleagues do supply those and other data and may have a broader understanding of recent trends in general.

 

Best regards,

Erik Zachte

Hello Eric,

 

I’m a german journalist writing for a large German Online Marketing Blog. I was wondering if you were willing to talk to me on the phone or via Skype about the development of Wikipedias Traffic in the last two years?

 

Best,

 

Roland
