33Across
Programmatic advertising exchange and audience targeting platform. 33Across scripts participate in header bidding auctions and sync user identifiers to enable targeted advertising across their publisher network.
Overview
33Across is a programmatic advertising exchange and audience targeting platform. Publishers use 33Across to monetize their ad inventory through header bidding, while advertisers use it to reach audiences across the 33Across publisher network.
What This Script Does
The 33Across script participates in header bidding auctions by evaluating available ad inventory and submitting bids in real time. It syncs user identifiers across its network by setting third-party cookies and firing pixel requests to match users with demand-side platforms. The script collects browser metadata, IP-derived location data, and browsing context to inform bid decisions and audience segmentation.
Consent & Compliance
Consent category: Marketing / Advertising
33Across processes personal data for programmatic advertising and cross-site user identification. GDPR requires explicit opt-in consent before any cookie setting or data collection. CCPA requires a "Do Not Sell or Share My Personal Information" mechanism. The ePrivacy Directive mandates consent for all non-essential cookies. 33Across participates in IAB TCF, and Purposes 1, 2, 3, 4, and 7 typically apply.
Should You Block This Without Consent?
Yes. 33Across is a pure advertising technology. No part of its functionality is required for website operation. Block until marketing consent is granted.
Is 33Across GDPR compliant?
33Across typically loads marketing trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So 33Across can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads 33Across, not on 33Across itself.
