Meta Lead Gen Custom Audiences
Drive Higher-Quality B2B Leads by Syncing Your ICP to Meta
Meta ads deliver volume but often miss on lead quality for B2B. Primer helps you bypass Meta’s limited native targeting by building and syncing custom audiences based on your Ideal Customer Profile (ICP).
By refining targeting in this way, you can improve lead qualification rates and reduce wasted ad spend. For detailed steps on how to set this up, refer to the visual walkthrough in Primer’s Meta Lead Gen guide.
How to Build and Sync ICP Audiences for Meta Lead Ads:
Create your ICP audience in Primer: Define targets by department, company size, seniority, and more.
Sync the audience to Meta: Push your custom audience directly into your Meta ad account as a customer list.
Launch Lead Ads campaigns: In Meta Ads Manager, create a Lead Gen or Website Conversion campaign and add the synced Primer audience as a Custom Audience. Optionally, create a 1% Lookalike and turn off Advantage+ targeting to keep full control.
Track lead quality: Add UTM parameters to your ad URLs to track performance, and use your CRM to match leads from Meta campaigns to assess qualification. Monitor key metrics like qualified sign-up rate, cost per qualified lead, and overall conversion rate.
Why It Works:
Meta is more cost-effective than LinkedIn
Many B2B brands find success with Meta ads—when targeting is right
Syncing your ICP improves match rates and lead quality dramatically
Recommended 60-Day Use Case Evaluation Plan
If your goal is to validate Primer’s match accuracy on Meta and then drive qualified leads, here’s a structured plan you can follow:
Step 1 — Validate Reach & Audience Integrity
Check match rates and audience sizes on Meta. Use Primer's "View Runs" modal in each audience to validate the matched size.
Review audience previews in Primer to confirm they align with your ICP.
Cross-check with LinkedIn: Sync the same audience to LinkedIn and use its audience breakdown as a neutral benchmark to validate composition. Open the audience in the LinkedIn Campaign Manager and click "View Insights"
Confirm ICP engagement using a reverse-IP tool (e.g., 6sense, Demandbase, Warmly) filtered by UTMs to see which accounts are engaging with Primer-powered campaigns.
Step 2 — Build Awareness & Retargeting Pools
Launch awareness and educational campaigns to your target accounts.
Track growth of retargeting audiences (note: building retargeting audiences off video engagement on Meta, not just website visits).
A growing retargeting pool is a key KPI before pushing harder on conversion.
Step 3 — Drive Qualified Leads
Test direct lead-gen with Instant Forms (expect a lot of personal emails as Meta defaults to these; follow up with a workflow requesting work emails).
Run website forms in parallel, which are stronger for work email capture—be sure these landing pages are heavily mobile-optimized.
Keep in mind Meta is a mobile-first channel, while many B2B conversions still complete on desktop. Attribution won’t fully connect mobile impressions to desktop signups, so a lack of lead volume may be misleading. Look for a spike in desktop direct & organic traffic if directly attributable last-click form submits seem low.
Step 4 — Evolve Measurement into Incrementality
Make sure to connect your CRM and install the Primer Pixel so that Primer can assist with attribution.
Take advantage of Primer's use of holdout groups to measure the true incremental lift of running ads beyond touch-based measurement.
Review performance weekly, then in days 30-60 double down on winners, pause laggards, and expand strong audiences.
