LinkedIn Advertising is a paid advertising platform within LinkedIn's professional network, accessed through LinkedIn Campaign Manager. It enables advertisers to serve sponsored content, text ads, message ads, and conversation ads to LinkedIn's 950+ million professional members. LinkedIn's unique advantage is B2B targeting — advertisers can target by job title, seniority, company size, industry, skills, and specific employer — making it the only major platform where you can reliably reach CFOs, CTOs, or procurement directors as distinct audiences rather than approximations.
LinkedIn Ads have higher CPCs than most other digital advertising platforms (typically £5-£15+ per click depending on targeting), but this cost is often justified for B2B businesses where the value of a qualified lead is high. A SaaS company acquiring a 500-employee enterprise customer worth £50,000/year can comfortably absorb a £500 LinkedIn Ads CPA that would be prohibitively expensive for a consumer product.
LinkedIn Ads formats
- Sponsored Content — native ads appearing in the LinkedIn feed; the most common format; supports single image, carousel, video, and document formats
- Text Ads — small sidebar ads with headline, description, and image; lower engagement but lowest CPCs
- Sponsored Messaging — InMail messages sent directly to LinkedIn users' inboxes; high engagement for relevant offers
- Conversation Ads — branching message ads with multiple response options
- Lead Gen Forms — pre-filled forms that capture lead data without leaving LinkedIn; reduces friction for lead capture
- Dynamic Ads — personalised ads using the viewer's own LinkedIn profile data (name, company, photo)
- Event Ads — promoting LinkedIn events to relevant professional audiences
LinkedIn Ads have a minimum daily budget of approximately £8/day and minimum bid floors that effectively make campaigns less than £1,000/month total investment difficult to run meaningfully. For most UK B2B campaigns, £2,000 to £5,000/month in ad spend allows sufficient impressions for meaningful lead volume. LinkedIn Ads tend to have longer sales cycles than Google Ads — expect to run campaigns for at least 90 days before drawing firm ROI conclusions. Start with Sponsored Content in the feed rather than InMail or text ads for the broadest initial reach.
They serve different purposes and work best together. Google Ads captures active demand — professionals who are already searching for a solution. LinkedIn Ads creates demand — reaching professionals who may need your product but haven't yet searched for it. Google Ads has lower CPCs but narrower audience targeting for B2B. LinkedIn Ads has higher CPCs but precise job-function targeting impossible to replicate elsewhere. The most effective B2B paid media strategies use LinkedIn for awareness and engagement (top of funnel) combined with Google Ads remarketing and branded search to capture the intent generated by LinkedIn exposure.
