What is iOS 26 Link Tracking Protection?

Quick Answer

iOS 26 Link Tracking Protection strips gclid, fbclid, and msclkid from URLs in all standard Safari browsing sessions before the page loads, expanding a feature previously limited to Private Browsing (Apple WebKit, 2025). When a WooCommerce customer taps a Google or Facebook ad on iPhone, the click identifier connecting that visit to the campaign is removed before your site receives the request. Without the click ID, the ad platform cannot attribute the conversion. The sale still happens in WooCommerce — Google Ads just never knows it came from an ad.

Full Answer

Here's the thing — Link Tracking Protection does not block the ad click itself. The customer still lands on your product page. They still buy. WooCommerce still records the order. What gets stripped is the tracking parameter — the gclid, fbclid, or msclkid appended to the URL — that tells the ad platform "this visit came from this specific ad click." Without it, the conversion goes dark in your ad reports.Apple introduced LTP in iOS 17 for Private Browsing, Mail, and Messages. With iOS 26, released September 2025, Apple's WebKit team expanded it to all standard browsing sessions. Safari holds roughly 24% of global browser traffic and over 50% of US mobile sessions. That is a significant share of ad-driven WooCommerce traffic losing its attribution link silently.The fix is architectural. LTP operates at the client side — it modifies the URL in the browser before page JavaScript runs. But the HTTP request that arrives at your server contains the full, unmodified URL. A server-side tracking setup reads the click ID from the incoming request at the HTTP layer, before Safari's protection can strip it. That is the approach Transmute Engine uses for WooCommerce stores — capturing what Safari removes before it is removed.
