Why LinkedIn Costs More (and Why That Can Be Fine)
Let's address the elephant in the room: LinkedIn Ads are expensive. Average CPC ranges from $5-$15, compared to $1-$3 on Meta and $2-$8 on Google Search.
So why would anyone pay that?
Because LinkedIn is the only platform where you can target by job title, company size, industry, seniority level, and skills — with reliable, self-reported data. On Meta, you're targeting interests that an algorithm guessed. On LinkedIn, you're targeting the CEO of a 50-person tech company because that's literally what their profile says.
For B2B, that precision changes the maths entirely. A $12 click that reaches a decision-maker is worth more than a $2 click that reaches someone who'll never have buying authority.
The numbers back this up:
- B2B marketers see 2x higher conversion rates on LinkedIn vs. other platforms
- 40% of B2B marketers call LinkedIn their most effective lead gen channel
- LinkedIn audiences have 2x the buying power of average web audiences
But — and this is important — LinkedIn Ads punish lazy campaigns hard. The high CPCs mean there's very little room for wasted spend.
Campaign Types and When to Use Each
Sponsored Content (Single Image, Video, Carousel)
Your ads appear natively in the LinkedIn feed.
Best for: Brand awareness, content promotion, lead generation
Single Image Ads:
- Most common format
- Strong visual + compelling copy
- Works for every funnel stage
- Introductory text (150 characters above the fold) is critical
Video Ads:
- Higher engagement rates than static
- Best for brand storytelling and thought leadership
- Keep under 30 seconds for awareness, up to 2 minutes for consideration
- Captions are essential (most watch on mute)
Carousel Ads:
- 2-10 swipeable cards
- Great for step-by-step processes, case studies, or multi-point messages
- Each card can have its own CTA
Lead Gen Forms
Pre-filled forms that open within LinkedIn — no landing page needed.
Best for: Lead capture with minimal friction
Why they work:
- Form fields auto-populate from the user's LinkedIn profile
- No page load, no external redirect
- Conversion rates 2-5x higher than landing pages
- Data quality is high (pulled from profile, not typed)
The trade-off: Lead quality can be lower because it's so easy to submit. Add a qualifying question (custom field) to filter serious enquiries from casual clicks.
Sponsored Messaging (Message Ads and Conversation Ads)
Deliver messages directly to users' LinkedIn inboxes.
Message Ads:
- Single CTA message
- Feels personal (from a person, not a company)
- 50% average open rate
- Best for event invitations, exclusive offers, direct outreach
Conversation Ads:
- Multiple CTAs within a choose-your-own-path message
- More interactive
- Good for qualification ("Are you a business owner? / Do you manage a team?")
Caution: LinkedIn limits how often users receive Message Ads to avoid inbox spam. Frequency is capped at one per member every 45 days.
Document Ads
Promote PDF content (whitepapers, guides, reports) directly in the feed. Users can preview the document without leaving LinkedIn.
Best for: Thought leadership, gated content, lead magnets
Gate options: Require lead gen form submission to unlock the full document, or let people browse freely.
Text Ads and Dynamic Ads
Text Ads: Small sidebar ads. Low CTR but cheap. Good for retargeting and brand visibility on a budget.
Spotlight Ads: Personalised ads featuring the user's profile photo. Attention-grabbing but can feel invasive.
Targeting: Where LinkedIn Shines
The Targeting Options
Company:
- Company name (target specific accounts)
- Company size (1-10, 11-50, 51-200, etc.)
- Industry
- Company revenue (estimated)
- Company growth rate
Role:
- Job title
- Job function (Marketing, Finance, IT, etc.)
- Seniority (Entry, Manager, Director, VP, C-Suite)
- Years of experience
Skills and Interests:
- Member skills (self-reported)
- Member interests
- Groups they belong to
Education:
- Degree type
- Field of study
- School name
Demographics:
- Location (country, region, city)
- Age (ranges)
- Gender
Audience Building Strategies
Strategy 1: Decision-Maker Targeting Company size: 50-500 employees
- Seniority: Director, VP, C-Suite
- Job function: Marketing
- Location: New Zealand
Reach: Small but highly qualified. Every impression reaches someone with buying power.
Strategy 2: Account-Based Marketing (ABM) Upload a list of target company names
- Layer on seniority and function filters
Reach: Very small, very precise. Perfect for enterprise sales with named target accounts.
Strategy 3: Lookalike / Predictive Audiences Upload your customer list → LinkedIn finds similar profiles
Reach: Broader but based on real customer data.
Strategy 4: Retargeting
- Website visitors (LinkedIn Insight Tag)
- Video viewers (25%, 50%, 75%, 95%)
- Lead gen form openers who didn't submit
- Company page visitors
- Event attendees
Audience Size Guidelines
- Sponsored Content: Minimum 50,000 for awareness, 20,000-50,000 for lead gen
- Message Ads: Minimum 15,000 (tighter targeting is fine)
- Retargeting: Whatever you've got (even 1,000 can work)
Too broad = wasted spend. Too narrow = delivery issues and high CPCs.
Creative That Works on LinkedIn
What LinkedIn Users Respond To
LinkedIn is not Instagram. The audience is in professional mode.
Works:
- Data and statistics ("We helped 200+ businesses increase leads by 3x")
- Thought leadership that challenges conventional wisdom
- Case studies with specific results
- Behind-the-scenes of your process
- Industry insights and trends
- Professional photography (real team, real office)
Doesn't work:
- Hard-sell discount offers
- Generic stock photography
- Vague corporate speak
- Memes (usually)
- Overly polished, inauthentic content
Ad Copy Formula
Hook (first line — must stop the scroll): "Most NZ businesses waste 40% of their ad budget. Here's why."
Body (value + credibility): "We audited 50 Google Ads accounts last quarter. The most common problem wasn't targeting or budget — it was tracking. Without proper conversion tracking, the AI can't optimise, and you're flying blind."
CTA (clear, specific): "Download our free tracking audit checklist →"
Image Guidelines
- Use real photos over illustrations (faces perform 2x better)
- High contrast colours (stand out in the feed)
- Minimal text overlay
- 1200x627px for single image ads
- Test 3-5 creative variations per campaign
Budgeting and Bidding
Minimum Budgets
LinkedIn recommends $25/day minimum. In practice, you need $50-$100/day for meaningful data, especially with precise targeting.
Monthly budget guidance:
- Testing/learning phase: $1,500-$3,000/month
- Established campaigns: $3,000-$10,000/month
- Aggressive B2B lead gen: $10,000+/month
Bidding Strategies
Maximum delivery (recommended for most): LinkedIn optimises delivery within your budget.
Cost cap: Set a maximum CPC or CPM. Gives more control but can limit delivery.
Manual bidding: Full control. Only for experienced advertisers managing large budgets.
Expected Costs (NZ/AU market, 2026)
| Metric | Range | |--------|-------| | CPC (Sponsored Content) | $5-$15 | | CPM (Sponsored Content) | $30-$80 | | Cost per Lead (Lead Gen Forms) | $30-$150 | | Cost per Message Send | $0.50-$1.50 | | CTR (Sponsored Content) | 0.4-0.7% |
Measuring What Matters
LinkedIn's reporting dashboard shows plenty of metrics. Focus on these:
Lead gen campaigns:
- Cost per lead (CPL)
- Lead form completion rate
- Lead-to-opportunity conversion rate (track in your CRM)
- Cost per qualified lead
Awareness campaigns:
- Reach and frequency
- Video view rate and completion rate
- Engagement rate
- Brand lift (if budget allows LinkedIn's Brand Lift testing)
Content promotion:
- CTR
- Engagement rate
- Website visits from LinkedIn
- Time on page from LinkedIn traffic (check in GA4)
The CRM Connection
LinkedIn's real ROI only becomes visible when you connect it to your CRM.
Set up:
- LinkedIn Insight Tag on your website
- Offline conversion imports (tell LinkedIn which leads closed)
- CRM integration (HubSpot, Salesforce, Pipedrive)
- UTM parameters on all ad URLs
Without this, you're measuring leads, not revenue. And leads that don't close are just expensive email addresses.
Common LinkedIn Ads Mistakes
- Targeting too broadly — "All marketers in New Zealand" is too wide. Layer company size, seniority, and function.
- Using landing pages when Lead Gen Forms would work better — test both, but Lead Gen Forms usually win on conversion rate
- Running one ad per campaign — always test 3-5 variations
- Ignoring the first line of copy — only ~150 characters show before "see more." That first line IS the ad.
- Not retargeting — website visitors and video viewers are warm audiences. Retargeting costs less and converts better.
- Budget too low to learn — $10/day won't generate enough data to optimise
- No negative targeting — exclude competitors, job seekers, students, and irrelevant industries
- Measuring CPL without tracking quality — a $30 lead that closes is worth more than a $10 lead that ghosts you
Getting Started
- Install the LinkedIn Insight Tag on your website
- Define your ideal customer profile (ICP) in LinkedIn's targeting terms
- Start with Sponsored Content + Lead Gen Forms
- Create 3-5 ad variations
- Set $50-$100/day budget
- Run for 2 weeks before making changes
- Connect leads to your CRM and track downstream
- Optimise based on cost per qualified lead, not just cost per lead
LinkedIn Ads aren't for everyone. If your customer isn't on LinkedIn, or your deal size is under $1,000, the economics probably don't work. But if you're selling B2B with deal sizes above $2,000 and your buyers are professionals — it's one of the most efficient channels available.
