iOS 26: What Marketers Need to Know — and How Server-Side Tracking Can Help
September 22, 2025
5 Minute Read

Apple has done it again. With the release of iOS 26, new privacy updates are reshaping the way marketers collect and measure data. If you depend on accurate attribution to understand the impact of your digital campaigns, this update matters.
At Be Found Online®, we’ve been tracking these changes closely. Here’s what you need to know — and how you can adapt.
What’s New in iOS 26?
1. Link Tracking Protection (LTP)
Apple is expanding Link Tracking Protection in Safari, Mail, and Messages. This means certain click IDs used by ad platforms (like Google’s gclid or Meta’s fbclid) may be stripped out of URLs.
Impact: Attribution pipelines that depend on these IDs become less reliable. Campaign performance data may appear weaker than it actually is.
2. Fingerprinting Protections
Safari 26 now blocks or randomizes many signals that advertisers once used for fingerprinting (device details, browser metadata, etc.).
Impact: Retargeting, cross-device attribution, and probabilistic modeling all get less precise.
3. Messaging & Email Filtering
Messages from unknown senders (like SMS opt-in confirmations) may be filtered into an “Unknown Senders” folder. Email campaigns may also lose some visibility into clicks if parameters are stripped.
Impact: Lower engagement rates and more friction in opt-in flows.
4. Privacy-First AI Features
Apple is pushing more intelligence onto the device, limiting the amount of raw behavior data that leaves a user’s phone.
Impact: Third-party data collection shrinks further, reinforcing the need for a first-party data strategy.
Why This Matters for Advertising
Across ad platforms like Google, Meta, TikTok, and programmatic, these changes mean:
- Less reliable attribution: Click IDs vanish, making it harder to connect the dots from ad click to conversion.
- Weaker retargeting: Audience building becomes noisier with fingerprinting protections.
- Shaky automated bidding: Smart bidding systems that rely on conversion signals may optimize less effectively.
- Reporting gaps: Campaigns could look underperforming when, in reality, conversions are being missed in reporting.
Server-Side Tracking: A Smart Solution
While we can’t reverse Apple’s privacy-first stance, server-side tracking offers a way forward.
What Is Server-Side Tracking?
Server-side tracking (or server-to-server event forwarding) captures conversion events directly on your server and passes them to platforms like Google, Meta, or TikTok via secure APIs.
Why Server-Side Tracking Helps
- Bypasses Browser Limits: Because tracking happens on your server, Apple’s browser-based stripping has less effect.
- Preserves Attribution: Even when click IDs are stripped, server-side setups can still pass other identifiers (like UTMs or hashed emails) to ad platforms.
- Improves Data Quality: You control the data, ensure it’s consent-compliant, and enrich it before sending.
What Server-Side Tracking Does Not Do
Server-side tracking isn’t a silver bullet. If Apple removes parameters before they ever hit your site, you can’t recover them. And you’ll still need proper consent management in place. But when combined with a first-party data strategy and modern measurement methods (like incrementality testing or media mix modeling), it’s one of the most effective ways to maintain visibility.
How BFO Can Help
At Be Found Online, we help brands navigate these shifts every day. Our team can:
- Audit your current tracking setup to spot where iOS 26 will create blind spots.
- Implement server-side tracking (Google Enhanced Conversions, Meta CAPI, TikTok Events API, etc.) for stronger signal recovery.
- Build strategies around first-party data collection, so you’re less dependent on third-party identifiers.
- Apply advanced measurement models that go beyond click IDs to prove campaign impact.
Final Takeaway
Apple isn’t backing down on privacy — and marketers shouldn’t wait for a workaround that never comes. Instead, the future of measurement will be built on first-party data, server-side tracking, and smarter modeling.
If you’re ready to strengthen your data foundation and adapt to iOS 26, we’d love to help.
