LinkedIn B2B Advertising Tips
Professional Tone
LinkedIn is a professional network. Maintain a business-appropriate tone and focus on value proposition rather than hard selling.
Target Precisely
LinkedIn's targeting options are the most advanced for B2B. Use job titles, company size, industries, and seniority for laser-focused campaigns.
Lead Gen Forms
Use LinkedIn's native lead gen forms to collect high-quality leads without users leaving the platform. Pre-filled forms increase conversion rates.
Test & Iterate
B2B buying cycles are longer. Give campaigns time to mature, typically 2-4 weeks, before making major changes.
