ssp-sync.criteo.com: Criteo’s Relentless Ad Tracking

Criteo’s ssp-sync.criteo.com is a tracker that follows your online activity to power retargeting ads—those annoying banners that chase you after viewing a product. It invades your privacy by collecting and syncing data for advertising purposes. Let’s expose its tactics and show you how to fight back.

What Is ssp-sync.criteo.com?

This domain belongs to Criteo, a company specializing in personalized ads. It syncs data across platforms to ensure advertisers can target you wherever you go online. As Privacy Auditors, we’re concerned about how much of your personal browsing history it captures.

Data It Collects

When you visit sites with Criteo tracking, it snatches:

• Browsing History: Logs URLs and product pages for ad retargeting.
• IP Address: Tracks your location for region-specific ads.
• Device ID: Grabs unique identifiers like advertising IDs for cross-device tracking.
• Cookie IDs: Syncs trackers like ‘uid’ to follow you over time.
• Ad Interactions: Records clicks and impressions for campaign analysis.
• User-Agent: Notes browser and OS details for device profiling.
• Session Data: Captures time spent on pages for behavior tracking.

This creates a detailed map of your online shopping and interests.

Who Gets Your Data?

Criteo doesn’t keep this information to itself:

• Advertiser: Shares data with companies using Criteo for retargeting ads.
• Third-Party Adtech Partner: Transfers data via Criteo’s marketplace for profile building.
• Data Processor: Sends info to cloud providers or subcontractors for storage and analytics.

How to Protect Yourself

Privacy Auditors want you to take control of your data:

• Block Trackers: Use Privacy Auditor’s paid service to halt ssp-sync.criteo.com scripts. The free version spots active trackers.
• Use a VPN: Mask your IP with a tool like Mullvad to hide your location.
• Switch to Privacy Browsers: Use Firefox with strict protection or Tor for anonymity.
• Disable JavaScript: Stop tracking scripts with browser settings or NoScript, though some sites may not work.
• Clear Cookies: Wipe trackers like ‘uid’ regularly to break persistent monitoring.

Layer these defenses to minimize Criteo’s grip on your data.
