Q: Do cookieless platforms work across all ad channels?

Most modern platforms support multiple channels including display, social, and native ads using contextual targeting and AI — no cookies required.

Introduction: Navigating B2B Advertising Post-Cookies

With third-party cookies on their way out by 2025, B2B marketers find themselves at a crossroads. Traditional retargeting tools that once relied on external cookies are fast becoming obsolete. But there’s a silver lining — AI-powered, privacy-compliant B2B ad platforms have stepped up, offering smarter, compliant ways to reach decision-makers.

Why third-party cookies are vanishing

Google, Safari, and Firefox have all announced varying degrees of third-party cookie deprecation due to rising privacy standards like GDPR, CCPA, and broad global consumer pressure. For B2B companies, this means behavioral targeting built around cookies will no longer be viable or ethical.

The rise of AI-powered intent targeting

Modern platforms now use machine learning and first-party data to predict a user’s professional interest or buying intent. Rather than stalking a website visitor through ads, these tools intelligently match content and offers to verified, in-market accounts across channels.

What Makes an Effective Cookieless B2B Ad Platform?

Privacy compliance and regulatory alignment

The best B2B ad platforms ensure alignment with laws like GDPR, HIPAA, and CCPA. They avoid storing or sharing personally identifiable data and rely on cohort-level behavior or consented first-party engagement.

First-party data integration

Cookieless targeting thrives on data you already own. Platforms that can sync with CRM systems (like Salesforce or HubSpot), customer data platforms (CDPs), or MAPs (Marketing Automation Platforms) offer more tailored targeting and segmentation.

Account-based marketing and predictive intent signals

ABM platforms that use predictive AI analyze multiple data points — including firmographics, technographics, keyword searches, and content interaction — to surface accounts showing in-market behavior without relying on personal cookies.

Top Cookieless B2B Ad Platforms for 2025

LinkedIn Ads: Social-first intent precision

LinkedIn natively matches targeting against job titles, industries, and company profiles, all without needing third-party cookies. Their platform has added AI layers to enhance lead gen, such as optimizing campaigns for buyer behavior signals within their ecosystem.

6sense: AI-powered ABM and predictive targeting

6sense is purpose-built for B2B intent data and AI-based targeting. It helps marketers uncover anonymous buying signals and activates campaigns across multiple ad channels. Their platform is frequently cited in Gartner’s and Forrester’s ABM tech guides.

Demandbase: Contextual and firmographic targeting at scale

Demandbase combines real-time firmographic data with contextual relevance. Instead of targeting individuals, it ensures ad delivery to the right buying committees at relevant companies using AI and natural language processing (NLP).

Metadata.io: Campaign automation meets AI insight

Metadata.io helps orchestrate B2B paid campaigns across social, display, and content syndication — all without third-party cookies. Its AI engine tests thousands of variations and optimizes based on pipeline contribution.

How These Platforms Replace Traditional Retargeting

AI-powered personalization over pixel tracking

Instead of tracking users with a pixel, cookieless platforms personalize based on content intent and real-time buyer signals. Algorithms prioritize relevance over repetition.

Combining CRM and buyer journey data

By integrating CRM histories, engagement scores, and funnel stages, these platforms allow advertisers to sequentially engage users across the funnel — whether or not they clicked on an earlier ad.

Contextual and semantic ad placement

AI-driven demand gen platforms can analyze a publisher’s content to context-match ads. This aligns sponsor messaging with timely topics and relevant industry news — without any need for cross-site tracking.

Choosing the Right Platform for Your B2B Funnel

Evaluating platform integrations with your tech stack

Native integrations with CDPs, analytics platforms (e.g., Google Analytics 4), and CRMs can make or break your ad ops efficiency. Check API support and the need for middleware connectors.

Budget alignment and scalable targeting

Platforms like LinkedIn offer variable minimum spends, while enterprise-focused tools like 6sense or Demandbase may command higher budgets but deliver deeper ABM impact. Consider scalability across business units.

Testing, measurement, and ROI tracking

Use A/B testing features and closed-loop attribution to measure success. The best AI ad tools will integrate with your pipeline and revenue tracking tools to report actual outcomes — not just vanity metrics.
