Natural Search Attribution Impacted by Latest iOS release?

We noticed our original referrer data starting to get stripped which moved what would have been Natural Search traffic into Direct throughout the summer, but especially in early August. Are there any ideas on if this is related to the Safari 26 browser update tied to an iOS release, and are there any work-arounds to get that traffic back in under Natural Search in Adobe Analytics?

@Jennifer_Dungan I found this article which explains why referrer data is being stripped. ​@robertc6820873 You may read this.

You can try to explicitly implement the following in the Adobe Analytics setup:
s.referrer = document.referrer;
This will help ensure that whenever the browser makes the referrer information available, the value is consistently captured and passed to Adobe Analytics. It is especially useful in cases involving custom implementations, SPA applications, or situations where the referrer value may otherwise not persist correctly across page navigations. However, it is important to note that if Safari itself suppresses or removes the referrer information due to privacy settings, then the browser does not expose that value to JavaScript at all. In such cases, Adobe Analytics cannot capture the referrer because the information is no longer available at the browser level. Therefore, while explicitly setting 's.referrer' can improve consistency and help preserve available referrer values, it cannot fully overcome Safari’s built-in privacy restrictions.

Hi ​@robertc6820873 ,

Before attributing this to Apple iOS releases, I have a few questions:

  1. Have you tried breaking down Direct by browser and OS? Try plotting browsers and OS over time (line graph). Did Chrome on Android and Chrome on desktop move too, or is it isolated to Safari/iOS? If all three moved together in August, it's Google-side. If only iOS moved, it's Apple.
  2. For the visits landing in Direct, does the Referrer / Referring Domain dimension show google.com at normal volume, while the Natural Search marketing channel drops?
  3. What is the click volume in Google Search Console over the same period? Did GSC clicks hold steady while Adobe Natural Search fell? If so, then it's probably an attribution issue. If GSC fell too, then this could be a real drop.

I would like to see screenshots of the table and the line graph to assess before jumping to conclusions. 

Looking forward to hearing back.

Appreciate you jumping in Arturo! I should note that we had been missing 20% of our site activity in Adobe and implemented a reverse proxy solution 5/5/26 which pushed more traffic to direct because a lot of this new-found traffic was coming from ad-blocker browsers. While we had been maybe making a poor assumption that the missing 20% of traffic was coming from each channel equally in this visual, the focus of the traffic shift should be on July/August.  

 

Here is the GSC vs Google Referrer in Adobe which demonstrates multiple spikes over the summer. 

Thank you,

Rob

Hi ​@robertc6820873 

 

For what it's worth, I’ve checked Safari 26 (and all sub-versions) against Referrer Type, Marketing Channels, and even my direct Paid/Natural Search dimensions… Traffic to “Search Engines” (Referrer Type), “Organic Search” (Marketing Channel), and “Natural Search” (Paid Search dimension) all look fine in my data (I checked trending since Aug 1, 2026 until yesterday).

 

I also checked Direct traffic (Type/Bookmarked Referrer Type and Direct Marketing Channel), there is no noticeable increase there that would indicate any sort of a shift.

 

It seems very unlikely that the issue is either with Safari 26, or with Adobe out of the box detection. If you are losing tracking, I think the investigation has to start with your own implementation and rules….

Hi ​@robertc6820873 ,

Thanks ​@Jennifer_Dungan  for taking a look at this, too! I have also looked at the data for Marketing Channels (Direct and Natural Search), referring domains, browsers and OS (including the Safari sub-versions) and I see no disruption on Natural Search or Direct after Safari 26 was launched.

Also, chart #4 (% Natural Traffic in Adobe Missing) jumps in two flat steps, around July 9-10 and August 4-6. Browser rollouts don't look like that (they look more like overlapping waves, see graph below). It could be worth exploring what could have changed around July 10 and August 4 in your implementation.

I did my reporting slightly differently..  I made a segment for Browser contains “Safari 26” (so it includes all sub-versions), the then compared Organic vs Direct, then I also looked at the same trend for “ALL Safari” (rather than trying to map all the versions of Safari on the same graph)

 

The percentages of Organic Search to Direct has stayed pretty constant since Jan 2025 (before the release of Safari 26 in Sept 2025). While traffic has been up or down, the comparative % breakdown between the channels is consistent.

You’re welcome. When investigating anything, I like to try various approaches… in this case, looking at All Safari vs Safari 26 (all variants) seemed to be a decent approach for confirming if traffic was consistent or shifting.

 

However, this doesn’t explain the root of ​@robertc6820873 issue … that seems to require more specific digging into the website.

Hi ​@Jennifer_Dungan , I like your approach.

In my case, I just graphed browser versions around the release of Safari 26 to make a comparison for ​@robertc6820873 on how browser version changes look in reporting, compared to the two marked step-ups seen on the last graph they shared, around July 9-10 and August 4-6.

I agree with you that this seems to be unrelated to browser version releases and more with the specifics of ​the implementation.

Hi team - we are in alignment and I am trying to figure our what could have possibly changed in our implementation. Our IT team is unsure what could have caused this, but we are bringing in Adswerve to help.

 

Thank you,

Rob

Good luck!

You may have to do some trickery to try and do some live testing where you can isolate your own page views, and check various scenarios…. 

 

In a browser, I will use the Developer Panel to modify links from Google Search (like adding a custom UTM I can follow, or pointing the link to our QA/Dev environment)… then try to dig into my isolated experience to try and see what is happening.
