Overview
IO Technologies is a programmatic advertising analytics platform. Their scripts collect impression-level data on ad serving events to provide transparency into programmatic supply chains for publishers and advertisers.
What This Script Does
- Collects impression-level data from programmatic ad serving events
- Monitors ad delivery across supply chain participants (SSPs, DSPs, exchanges)
- Tracks bid and win rates, latency, and fill metrics for ad slots
- Sets cookies or identifiers for session-level measurement
- Reports data to IO Technologies servers for supply chain analytics dashboards
Consent & Compliance
- Consent category: Analytics
- Applicable regulations: GDPR, ePrivacy Directive, CCPA
- Opt-in required: Yes under GDPR/ePrivacy when cookies or device identifiers are used.
- Supply chain analytics scripts collect data about ad serving rather than direct user targeting, but still set cookies and process device-level information.
Should You Block This Without Consent?
Conditional. IO Technologies scripts serve an analytics and transparency function for ad supply chains rather than user targeting. However, if they set cookies or collect device identifiers, consent is required under ePrivacy. Block alongside your other ad-related scripts until consent is obtained.
Is IO GDPR compliant?
IO typically loads analytics 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 IO 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 IO, not on IO itself.
