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:

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.

mubarakd5726232

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

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?

mubarakd5726232

Frank ?..

seems we're on our own ..

Can you please look to create something similar

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

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?

Hi,

Samsung also recently introduced 'Tracking Blocker' feature in their new browser, powered by Disconnect. This pretty much sounds like Apple's ITP.

Some Analytics customers reportedly experienced tracking issues where it blocks analytics scripts from loading and as a result it's unable to collect behaviour data.

Are we aware of this as well as Apple's ITP? What would be the impact of this in analytics data?

Thank you in advance!

Thanks for the heads up Brandon! After reading the article, it looks like all of the following have to be met:

The visitor is using a Samsung Android device
They are browsing via the Samsung browser, and not Chrome
They have explicitly enabled Tracking Blocker or have entered Secret Mode

I anticipate that it won't have as large an effect, since Samsung browser market share is significantly less than Safari. However, I will certainly bring it up with the team to make sure they're aware of it.

Brandon thanks for highlighting, I was able to download on my non-samsung android device and verify ..

Tracking blocker not enabled by default, however when enabled it was blocking our Adobe Analytics request.

Hi all,

From what i understand in the thread and the ITP article:

1) Adobe Analytics should not be impacted if it has a 1st party cookie on the domain (this is dependent upon the set up as outlined in the original link)

2) All other Adobe tools inc Advertising will be impacted as they are not using the same first party cookie as Analytics. i.e. we will not be able to target Safari 11 users, only measure them. Or is there a way for Adobe to take the Analytics 1st party cookies to feed Advertising for example?

It would be great to get confirmation as there's some conflicting messages around.
