Measure LinkedIn Ads Performance

Prerequisites

LinkedIn Insight Tag installed on your website
LinkedIn Marketing API access

Steps

Verify Insight Tag installation. Use the LinkedIn API to check tag status. The Insight Tag JavaScript snippet must be on all pages for conversion tracking to work.

Set up conversion actions via API. Define conversions using the Marketing API:

POST /v2/conversions
{
  "name": "Demo Requested",
  "type": "LEAD",
  "attributionType": "LAST_TOUCH_BY_CAMPAIGN",
  "conversionMethod": "PIXEL",
  "postClickAttributionWindowSize": 7,
  "viewThroughAttributionWindowSize": 1
}

Define conversions for: demo requested, sign-up completed, content downloaded.

Query campaign performance via API. Pull metrics:
```
GET /v2/adAnalytics?campaigns=urn:li:sponsoredCampaign:<id>&dateRange.start.year=2025
```
Key metrics: impressions, clicks, CTR, conversions, cost per conversion.
Segment performance by audience. Compare metrics across job functions, seniority levels, and company sizes via the API breakdown parameters to find your best-performing segments.
Track down-funnel metrics. Connect LinkedIn leads to Attio (via n8n) to measure which LinkedIn leads become pipeline and revenue. Calculate ROAS: total ad spend vs revenue from LinkedIn-sourced deals.
Build unified reporting. Sync LinkedIn ad performance data to PostHog via n8n. This lets you see LinkedIn ads alongside organic metrics in one dashboard. Run weekly reviews: pause campaigns with CPA > 2x target, increase budget on winners.
