Update:

I have been checking on the indexed link count over the last couple of months, and it has been roughly constant. Upon another check in the past week, it looked like it was time to go ahead with the robots.txt update.

Just yesterday, the start of a robots.txt entry for <lang>.zero.wikipedia.org has also been updated to instruct all robots like Googlebot to not index <lang>.zero.wikipedia.org. Looks like even more <lang>.zero.wikipedia.org pages may already be starting to fall out of the index.

Thanks for flagging this! Will keep watching the indexed links count as it dwindles.

Thanks again.

Okay, looks like the index of zero.wikipedia.org pages in Google has shrunk by some 20 million entries. Nonetheless, a number of really old pages (e.g., going back to 6-May-2013) are still in the Google index with article text. I'll set a reminder to check on the Google index again in 30 days, and hopefully then we can finally put the no-index rules in place at that time.

The good news is that many of the pages are now correctly suppressed in natural search as non-canonical pages. In other words, a user would need to go through omitted results or do a site:<domain> search to see them.

Update:

We've added an enhancement to Wikipedia Zero so that if a user who isn't on a participating carrier network navigates to a Wikipedia Zero page on <language>.zero.wikipedia.org, such as http://en.zero.wikipedia.org/wiki/Muse_%28band%29 , the user will be presented an option to visit the canonical URL of the article. If clicked, the canonical URL should get the user to the mobile or desktop version of the page, based on device type.

We're hoping that by next week the Google index will be refreshed so as to correctly mark the <language>.zero.wikipedia.org pages as duplicate pages in the omitted section. Upon confirmation of as much, the current plan is to introduce https://gerrit.wikimedia.org/r/#/c/69420/ to prevent indexing of <language>.zero.wikipedia.org altogether.

Kasper, after further analysis, it appears the patch introduced last week should clear this up within about 35 days. I'll set a reminder to validate as much.

"Disallow: /" in http://*.zero.wikipedia.org/robots.txt would suffice.
