Hi everyone! There seems to be quite a bit of buzz surrounding webkit's ITP feature. We have authored the following KB article to help answer any questions you might have:

Adobe Analytics and ITP

If you have any follow-up questions, feel free to ask them here.

Is it possible to identify/trend no. of unique visitors relying on fallback method(s). We're currently using Adobe's third-party cookie as we need to report on uniques across multiple domains and therefore helpful to measure any impact/change.

If changing your implementation to use MCVID is not an option and you absolutely must stay with friendly 3rd party cookies, everyone who is using Safari is going to be your total impact.

Luckily one of the fallback methods is to use a 1st party cookie on the domain visited, so unique visitors per domain will still remain fairly accurate.

We are using omtrdc.net which in theory should not have had an impact as these cookies were already being blocked.  However I've noted a sizable increase in Unique Visitors across all iOS devices.  Are you aware of this and why this would be the case.

ITP is not necessarily directly correlated with iOS, but rather the safari browser. People browsing via Chrome on Mac won't be affected by ITP, while people browsing via Safari on Windows will.

Are you getting the same trend line by only including people browsing via Safari?

Yes, I'd based on a significant proportion of our audience using Safari being iOS users.

See below ...

Interestingly increase in Uniques only applies if Safari AND iOS, however more importantly (my previous point) it should have not impacted third party omtrdc.net cookie as it was already being blocked by safari

hmm .. only applies to entires to our homepage .. and no referrer

1347766_pastedImage_0.png

It's across all domains (ips) inc those assigned to larger service providers (ie unlikely to be bots).  Whilst it's also possible these may be new device purchases it does seem highly unlikely with uniques on mobile almost double

Hello everyone,

since the iOS/safari 11 update we have a problem with rising unique visitors on mobile iOS as well. We cannot use first party cookies / MCVID either, since we have to track data from multiple domains. If I understand your "Adobe Analytics and ITP" article correctly, then this problem shouldn't occur at all, since the third party cookies should've already been blocked by safari before. We're using omtrdc.net, too. It sounds like a quite similar scenario as mubarakd5726232's.​

The even bigger problem is, that these additional visits/sessions mess up our marketing channels data, since the "new" sessions are recognized as internal visits (HTTP-referrer comes from internal domain on session start).

Is there anything we can do to solve this problem?

Frank ?..

seems we're on our own ..

Can you please look to create something similar

1357359_pastedImage_0.png

segment detail for Bot Review : 1PV/Visit is ..

1357360_pastedImage_1.png

If you could then duplicate the report but have breakdown by day instead ...

You'll notice a significant proportion in the increase is from new uniques only looking at 1 pv/visit .. ie appears to be an issue with fallback

What I've seen is

1. the weekly uniques increase (with above segments applied) .. is almost 100% .. and with no increase in PVs/Visits

2. the average daily uniques have only increased by 20%

.. so it seems very likely a percentage of users are being seen as uniques on every visit and/or possibly on page view.

If our data is consistent that would confirm an issue at Adobe/Apple end.

Hello Mubarak?

I recreated the report on my end but it did not show the same result.

I get "new" Visits/Visitors which do have a referrer and also create more than only one page view each. The problem occurs when a user hops from one domain to the other in our case (can be identified via entry pages). This should be prevented by fallback methods (User Agent + IP) normally, but somehow this doesn't seem to work anymore for iOS 11 users.

Please take a look at the increasing share of Apple users starting in week Sep 25, 2017 running into the Internal URL Filter:

Do you see a similar problem with your internal URL filter maybe?
