Understanding Each Platform’s Role

SCHEDULE A DEMO

Primer

Primer is an identity resolution tool built for B2B marketers. Its main function is to help businesses improve match rates when uploading contact lists to ad platforms such as Facebook, YouTube, or Google.

By mapping business identities to personal identifiers, Primer allows advertisers to deliver campaigns to decision-makers on consumer platforms while maintaining data privacy compliance.

LeadiLibrary

AudienceLab functions as a full audience data platform. It combines verified online and offline data, behavioral intelligence, and real-time enrichment to help advertisers identify and activate audiences across multiple systems.

Rather than focusing only on improving ad platform match rates, AudienceLab enables users to build, enrich, and own their audiences for long-term scalability.

Data and Identity Resolution

Both solutions address data matching and identity challenges, but with different approaches.

Primer emphasizes probabilistic identity resolution to connect business contacts with consumer platform identifiers.

AudienceLab performs deterministic matching, verifying each data point across multiple trusted online and offline databases for a 95% verified accuracy rate.

The main distinction: Primer focuses on improving visibility for existing lists, while AudienceLab provides verified audiences that can be used across marketing and sales ecosystems.

Behavioral and Intent Data

Another point of difference is behavioral coverage.

Primer specializes in audience identity, not behavioral activity.

AudienceLab tracks and analyzes more than 60 billion URLs and behaviors weekly to give advertisers visibility into what their audiences are researching, visiting, or engaging with online.

This behavioral component helps users align campaigns with real buyer intent signals instead of relying only on static audience lists.

Data Verification and Accuracy

Both companies publish match rate benchmarks.

Primer reports match rates between 40% and 90%, depending on the ad platform and data quality.

AudienceLab reports a verified contact accuracy of 95% and match rates between 70% and 95%, depending on the channel and audience type.

Both approaches aim to improve ad efficiency, but AudienceLab’s inclusion of offline and behavioral data enables deeper accuracy validation.

Performance and Scalability

Primer is ideal for marketing teams running campaigns primarily on B2C ad channels. It provides a measurable improvement in match rates for B2B advertisers who rely heavily on Meta or Google Ads.

AudienceLab supports both B2B and B2C advertisers who want scalable data ownership and activation beyond a single channel. Its platform is designed to serve agencies, enterprise brands, and multi-channel marketing operations.

This behavioral component helps users align campaigns with real buyer intent signals instead of relying only on static audience lists.

When to Use Each Platform

Audience Lab gives the advertiser complete control over their data allowing them to target any audience, identify any traffic and match any data to use on any platform.

Need both B2B and B2C verified audiences.
