BlueConic

Overview

BlueConic is a customer data platform (CDP) that enables publishers, retailers, and media companies to build unified first-party customer profiles from behavioral data collected across their digital properties. It is one of the older CDPs in the market (founded 2010) and is widely used by media publishers and retailers who want to activate their first-party audience data for personalization and monetization without relying on third-party cookies.

BlueConic's key capabilities include profile unification, audience segmentation, onsite personalization, and data activation — syncing audience segments to advertising platforms, email marketing systems, and data warehouses. On websites where BlueConic is deployed, it operates as a significant data collection layer.

What This Script Does

BlueConic's script (cdn.blueconic.com or client-specific CDN paths) deploys as a core tracking and personalization layer:

Behavioral event capture: The script captures page-level events — page views, article reads, content categories viewed, product interactions, search queries, and custom events — on every page it loads. These events are attributed to a persistent visitor profile in BlueConic's profile store.

Persistent visitor identification: BlueConic sets first-party cookies (typically bcSessionId for the current session and bcCookieId as the persistent visitor identifier) under the implementing website's domain. The bcCookieId cookie persists for an extended period (commonly 2 years) and is used to link all behavioral events from a visitor across sessions into a single longitudinal profile.

Profile enrichment: As visitors browse, BlueConic enriches their profiles with derived attributes — content affinity scores, browsing frequency, recency, interest categories, and segment membership. For logged-in users, the anonymous cookie-based profile can be merged with authenticated identity (email, subscriber ID), creating a rich known-user profile.

Real-time segmentation: BlueConic evaluates visitors against segment rules in real time on each page load, determining which audience segments the visitor belongs to based on their accumulated profile data. Segment membership drives personalization decisions.

Onsite personalization: Based on segment membership and profile attributes, BlueConic's script can modify page content — swapping out banners, showing targeted offers, altering paywalls or subscription prompts, or loading different content variants. This personalization layer executes client-side after the profile evaluation.

External data activation: Profile data and segment memberships are synced to connected platforms — advertising platforms (Google DV360, The Trade Desk, Facebook Audiences), email platforms (Salesforce Marketing Cloud, Braze), and data warehouses. This syndication of behavioral profiles to advertising platforms is particularly significant from a GDPR perspective.

Consent & Compliance

BlueConic combines both analytics (behavioral profiling) and functional (personalization) capabilities, requiring consent for both:

• GDPR / ePrivacy: The persistent bcCookieId cookie requires prior opt-in consent under the ePrivacy Directive. Under GDPR, the behavioral profiling and — especially — the sharing of audience segments with advertising platforms requires consent under Article 6(1)(a). Legitimate interests is an unlikely lawful basis given the extent of profiling and data sharing with third-party ad platforms.
• IAB TCF: BlueConic participates in the IAB Transparency and Consent Framework (TCF 2.x) as both a Vendor and Publisher CMP-integrated platform. Relevant TCF purposes include Purpose 1 (Store/access device information), Purpose 3 (Create a personalised ads profile), Purpose 4 (Select personalised ads), Purpose 5 (Create a personalised content profile), and Purpose 6 (Select personalised content).
• CCPA/CPRA: The behavioral profiles and audience segment syndication to advertising platforms likely constitutes a "sale" or "sharing" of personal information under CCPA/CPRA, requiring a Do Not Sell/Share opt-out mechanism and disclosure in the privacy policy.
• EU-US transfers: BlueConic is a Dutch company (Groningen) with US operations. Data flows between BlueConic's EU and US infrastructure are covered by BlueConic's EU-US Data Privacy Framework certification and standard contractual clauses in customer DPAs.

Should You Block This Without Consent?

Yes. BlueConic builds persistent behavioral profiles from multi-session tracking data and syndicates those profiles to advertising platforms. Both the persistent identification and the data activation to ad platforms require prior consent under GDPR and ePrivacy. Block until analytics and/or marketing consent is granted depending on how BlueConic is configured on your specific implementation.
