Offline conversions, Lead Gen Forms, and Conversion Tracking are all effective strategies for lead generation and tracking conversions. Offline conversions allow you to track sales that happen outside of LinkedIn, integrating them with your online efforts. Lead Gen Forms are pre-filled forms within LinkedIn ads that make it easy for prospects to share their information, directly generating leads. Conversion Tracking uses the LinkedIn Insight Tag to monitor actions users take on your website after clicking your ads, providing data on conversions like purchases or sign-ups. Activity ads and follower ads are primarily for engagement and brand awareness, not direct lead generation or conversion tracking.
