Common Mistakes

1. Targeting Too Narrow

LinkedIn costs more. Tiny audiences = high CPMs. Aim for 50K+ audience.

2. Consumer-Style Creative

B2B audiences expect professional content. Match the platform tone.

3. Ignoring Lead Quality

Cheap leads aren't valuable. Track downstream metrics.

4. Infrequent Posting

Algorithm favors consistent activity. Maintain regular presence.

5. No Retargeting

High CPCs make retargeting essential. Build and use audiences.

Key Takeaways

LinkedIn is premium - higher cost, higher quality

Professional targeting is unmatched for B2B

Lead Gen Forms reduce friction significantly

ABM capabilities enable precision targeting

Content quality matters - invest in creative

Track full funnel - not just lead cost

Conclusion

LinkedIn Ads offer unparalleled access to professional audiences for B2B marketing. Success requires understanding the platform's premium nature and creating content that resonates with business professionals.
