What are the risks of turning this on? Do we need to do any validation when the change has been deployed? Is there any situation we might need to rollback?

I think we would probably want to monitor pageviews and ensure they're not going down, perhaps do a quick analysis. Given the results of T234807: Determine impact of $wgMFNoindexPages search traffic to arwiki, zhwiki, hiwiki, itwiki, nlwiki, kowiki, this seems unlikely. @MNeisler - what do you think?

I agree. The results of the analysis do not indicate any reason to suspect a negative change to either desktop or mobile traffic due to this fix. I think maybe a quick review of pageviews (specifically search-referred) following deployment would be sufficient just to confirm no major negative changes have occurred.

@MNeisler @ovasileva: Is there a task tracking the quick review of search-referred pageviews or would you prefer that this be the task so as not to fragment the conversation too much? If the former, then I'll happily sign this task off.

phuedx set the point value for this task to 1.Aug 21 2020, 11:54 AM

I've been bold and estimated this task since it's Ready for Signoff already (/cc @MBinder_WMF). I voted an XS as this was a configuration change and we don't include Product Analytics' work in our estimates.

I just created a task (T261018) to check pageviews.

Thank you @phuedx and @MNeisler! Resolving this and will follow up on the other task. +1 that we need just a quick check as we did the more thorough analysis in T234807: Determine impact of $wgMFNoindexPages search traffic to arwiki, zhwiki, hiwiki, itwiki, nlwiki, kowiki
