LinkedIn ad spend that optimizes only on form fills tends to attract a lot of unqualified leads — students, job seekers, partner pitches. Pushing MQL and Demo Booked events through CAPI tells LinkedIn what you actually care about, and the audience composition shifts within 4–6 weeks.
What to send
Send the same depth of events as Meta and Google: Lead, MQL, SQL, Demo Booked, Demo Attended, Closed-Won (with deal amount). Cometly handles the API calls automatically once the LinkedIn integration is connected.
For ABM-heavy programs, configure account-level conversions where LinkedIn supports it. That lets you optimize on whether an entire target account engaged, not whether a single contact filled a form.
- Lead — form fill (the baseline)
- MQL — lifecycle stage update from CRM
- Demo Booked — calendar event creation
- Demo Attended — meeting actually happened
- Closed-Won — with deal amount for value-based bidding
Pairing with matched audiences
Once CAPI is live, build matched audiences from the high-intent events: people who attended a demo, accounts that converted to closed-won, target accounts that engaged across multiple ads. These audiences (and 1% lookalikes built from them) consistently outperform broad targeting on LinkedIn.
Refresh the matched audiences weekly so they reflect the current quarter’s ICP rather than last quarter’s cohort.
What to watch for.
- Optimizing only on Lead Gen Form completions
Without CAPI, LinkedIn has no choice. With CAPI, you can push deeper events — use them.
- Sending events without identifiers
LinkedIn needs hashed email and the LinkedIn click ID for high match quality. Cometly forwards both — verify it’s configured.
- Letting matched audiences go stale
An audience built six months ago no longer represents your current customers. Refresh weekly.
Recap.
- Send Demo Booked and Demo Attended events as the primary optimization signals
- Add Closed-Won with the deal amount for value-based bidding
- Use account-level conversions where supported to align with ABM measurement
- Layer matched-audience and account-targeting against your closed-won audience
