Apple Just Made Safari Users Harder to Retarget
Apple's latest iOS update blocks The Trade Desk from serving ads on Safari. Not tracking. Not targeting. Serving. If your display or retargeting campaigns run on a DSP built on TTD's infrastructure, which a lot of them do even when the invoice says a different agency name, Safari and iOS traffic just got a lot harder to reach.
Here's why that matters for a leasing budget specifically, not advertisers in general. Safari is the default browser on every iPhone, and a meaningful chunk of your prospect traffic, especially anyone browsing apartment listings on their phone during a lunch break, is on an Apple device. If your retargeting pixel fires but the ad can't actually serve on that browser, you're paying to identify a prospect you then can't show an ad to. That's not a tracking gap. That's wasted spend with a receipt.
AdExchanger framed this as part of a bigger question about whether the open web is growing, dying, or just turning into something else. For your purposes, skip the philosophy. The practical question is whether your media vendor is still buying inventory as if Safari reach is unaffected, and whether your reporting is about to show a drop that has nothing to do with your creative or your offer.
This is exactly the kind of change that slides past a marketing director because it sounds like an engineering problem. It isn't. It's a reach problem, and reach problems show up as fewer leads with no explanation attached unless you ask for one.
- 01What percentage of our programmatic impressions over the last 90 days served on Safari or iOS, and what percentage do you expect that to be next month?
- 02Which DSP or ad server actually serves our retargeting ads, and does it run on The Trade Desk's infrastructure, directly or through a reseller?
- 03If Safari serving is currently blocked, what alternative path are you using, a different SSP, a different identifier, a different browser weighting, and when did that change go live?
- 04Will our monthly reporting show a reach or impression drop next month, and if so, how will you flag it so it doesn't get read as a performance problem on our end?
- 05Are you shifting budget away from Safari-heavy inventory toward other channels, and if so, which ones and at what cost per lead?
- 06Is there a fix or workaround expected from Apple or The Trade Desk, and does the source give any timeline for that, or is this open-ended for now?
