Use ContactLevel to Drive Higher Quality Leads from LinkedIn
Sometimes LinkedIn's native filters aren't strict enough. Build a clean audience with ContactLevel and import it to LinkedIn for higher quality conversions.
Without ContactLevel
LinkedIn Ads are powerful for B2B, but native title, attribute, and industry targeting often let the wrong users through: mid-level roles instead of senior buyers, industries outside your core market, titles that "sound close" but don't match your ICP. Those bad leads inflate CPL and muddy your funnel.
With ContactLevel
ContactLevel lets you create precise ICP audiences and sync them to LinkedIn to tighten targeting, improve quality, and lift your results with 85%+ match rates.
How It Works
Create ICP Audience in ContactLevel
Define your ideal companies, departments, seniorities, and titles. You can also pull in your ABM account list via CRM or CSV. Preview lets you verify quality before syncing.
Sync to LinkedIn
Push your ICP audience into LinkedIn as a matched list for use in your campaigns. Note: Matched Audiences take up to 72 hours to fully populate, so plan accordingly.
Launch A/B Test Campaigns
Run a head-to-head test: Control uses LinkedIn's native attribute targeting (titles, functions, seniorities). Test uses your ContactLevel matched list.
Track Qualification Rate
Use CRM tracking to measure form-completion rates, qualification rates, CPL, CPM, and CPA. Run the test for 1-2 weeks and compare.
Why It Works
Why setting up LinkedIn Matched Audiences is harder than it should be
LinkedIn Matched Audiences is the right tool. The setup process is the problem.
You upload your CRM CSV. LinkedIn matches work emails to user profiles. Match rate comes back at 30-40%. The audience activates if you have 300+ matched users; below that it sits inactive. Most B2B teams discover this after they've already structured their campaign.
Then you wait for LinkedIn's match window to refresh. You realize half your ICP isn't on LinkedIn at all. You realize the half who are use personal emails for their LinkedIn accounts, not work emails. Your CSV is matching the wrong identifier.
Most B2B teams give up here. They run interest-based targeting on LinkedIn (which works better than Meta's interest targeting, but still not as well as named contacts) and accept the cost.
How to set up LinkedIn Matched Audiences with ContactLevel
The setup that actually works:
- Build the audience in ContactLevel, not in LinkedIn directly. Filter by role, company size, industry, and any first-party signals (CRM stage, past engagement).
- ContactLevel enriches the contact list with personal identifiers — including the personal emails LinkedIn uses for account registration.
- Sync to LinkedIn Campaign Manager as a Matched Audience. Match rate jumps from 30% native to 70-90% with enrichment.
- Audience activates immediately if you cross the 300+ matched user threshold (which most B2B lists do once enriched).
- Use the Matched Audience in any LinkedIn campaign type: Sponsored Content, Sponsored Messaging, Thought Leader Ads, Text Ads, Dynamic Ads.
The whole process takes 90 minutes, including connecting LinkedIn to ContactLevel. Once connected, future audience updates flow in real-time. Add a contact to your CRM, they appear in your LinkedIn audience. Remove a contact, they leave.
The technical mechanism: ContactLevel uses LinkedIn's API to push hashed personal identifiers. LinkedIn matches against user accounts. Higher identifier match rate = higher audience match rate = more reach.
When to use this play
Set up LinkedIn Matched Audiences when:
→ You have a defined ICP list (CRM contacts, target accounts, named buying committee) → Your audience is at least 400-500 contacts (to clear LinkedIn's 300+ matched user minimum after enrichment) → Your ACV justifies LinkedIn's $30-80 CPM (typically $10k+ ACV) → You're running ABM, retargeting, or named-contact campaigns
Skip Matched Audiences setup when:
→ Your list is under 400 contacts (even with enrichment, won't activate) → Your ICP isn't on LinkedIn (some blue-collar B2B verticals) → Your ACV is under $5k (LinkedIn CPMs eat the margin)
Frequently asked questions
How do I set up LinkedIn Matched Audiences step by step?
In ContactLevel: build the audience using filters. Connect your LinkedIn Ads account. Click "Sync to LinkedIn." Match runs within 30 minutes. In LinkedIn Campaign Manager: navigate to Audiences → Matched Audiences. Find your synced list (named after your ContactLevel audience). Use it as the audience source on any campaign.
What's the minimum audience size for LinkedIn Matched Audiences?
300 matched users to activate. With native CSV upload at 30% match, you need 1,000+ contacts to clear the floor. With ContactLevel at 80% match, 400 contacts works. For useful frequency in B2B, aim for 1,000+ contacts in the audience.
Why is my LinkedIn match rate so low when I upload directly?
Because work emails don't match LinkedIn accounts. Most professionals signed up for LinkedIn with personal emails (gmail, yahoo, hotmail) before they had their current work email. ContactLevel solves this by enriching with the personal identifiers LinkedIn actually recognizes.
How long does the LinkedIn match process take?
15-30 minutes for the initial match after sync. After that, the audience updates in real-time as ContactLevel adds or removes contacts.
What's the difference between Matched Audiences and Predictive Audiences?
Matched Audiences = your exact contacts (matched). Predictive Audiences = LinkedIn's lookalike-equivalent expanded from a Matched seed. Use Matched for precision (named contacts only). Use Predictive for expansion (find similar people).
Can I use the same Matched Audience across multiple LinkedIn campaigns?
Yes. One Matched Audience can be used as the source on as many campaigns as you want. Sponsored Content, Sponsored Messaging, Thought Leader Ads, Dynamic Ads. Same audience.
