Budget: Start with a daily or lifetime budget. Minimums apply.

Bidding Goals:

Budgeting Tip: Allocate enough budget to run your campaign for at least 2-4 weeks to gather meaningful data.

  • Install the LinkedIn Insight Tag on your website.
  • Create specific conversion events (e.g., “Demo Booked,” “Whitepaper Download,” “Free Trial Sign-up”).
  • This allows you to track conversions, optimize campaigns, and build retargeting audiences.

7. Launch, Monitor, & Optimize

  • A/B Test Everything: Experiment with different ad copy, creatives, headlines, CTAs, and even audience segments. You’ll be surprised what works best!
  • Daily Monitoring: Keep an eye on key metrics like CTR (Click-Through Rate), CPC (Cost Per Click), CPL (Cost Per Lead), and conversion rates.
  • Frequency: Watch your ad frequency. If users see your ad too often, they’ll experience ad fatigue, and your performance will drop. Adjust bids or refresh creatives.
  • Adjust Bids: If a campaign isn’t spending its budget, consider increasing your bid. If it’s overspending or underperforming, lower it.
  • Rotate Creatives: Keep your ads fresh to avoid ad blindness.
