The £50,000 Targeting Mistake
Last month, a manufacturing company showed us their LinkedIn campaign targeting "business owners aged 25-65 in the UK." They'd spent £50,000 over 6 months and generated exactly zero qualified leads. Zero.
Their £25,000 industrial equipment was being advertised to university students, freelance consultants, and corner shop owners. None of whom could afford it, use it, or had any need for it.
This is what happens when you target "everyone" - you reach no one who matters.
Why Broad Targeting Destroys Your Budget
High Cost-Per-Click
Competing against every advertiser for broad audiences
Low Relevance Scores
Generic ads to broad audiences get punished by algorithms
Unqualified Traffic
Students, job seekers, and wrong industries clicking your ads
Budget Wastage
80% of spend going to people who can't buy
How Ad Platforms Actually Work (And Why Precision Wins)
The Auction Reality
LinkedIn and Facebook run auctions for every ad placement. You're not just competing on price - you're competing on relevance. The platform wants to show ads people will engage with.
Relevance Score Formula:
Ad Relevance = (Target Audience Match × Content Relevance × Expected Engagement) ÷ Competition Level
When you target "business owners aged 25-65," you're competing against:
- • Insurance companies targeting all business owners
- • Accountancy firms targeting all business owners
- • Business coaches targeting all business owners
- • Banking services targeting all business owners
- • Every other B2B company making the same mistake
When you target "Operations Directors at Manufacturing companies with 100-500 employees," you're competing against maybe 5-10 other advertisers. The platform gives you better placement at lower cost.
The Targeting Pyramid: Layer Your Way to Success
Effective B2B targeting works in layers. Each layer filters out unqualified prospects and concentrates your budget on people who can actually buy from you.
Company List, or Company Size + Industry
All businesses
An uploaded list of named target companies. No list yet? Manufacturing, Engineering, Construction at 50-500 employees
Puts your budget on the firms that can actually buy, and removes startups and enterprises outside your sweet spot
Job Titles
Business owners, or job function and seniority stacked together
Operations Director, IT Director, Finance Director
Reaches the people who sign off. Don't stack job function or seniority on top: LinkedIn treats them as OR with job titles, so they widen the audience instead of narrowing it
Exclusions, Added Gradually
Every exclusion loaded on day one, or none at all
Wrong job titles, competitors, existing clients and job seekers, added as the demographics report shows wasted clicks
Cuts wasted spend using real data, without starving the campaign of reach before it has learned anything

Your 3-Step Targeting Implementation Framework
1Identify Your Ideal Customer Profile (ICP)
Stop guessing and start with data. Look at your best customers and identify patterns.
- Analyse your top 10 customers by revenue
- Find common job titles, company sizes, industries
- Identify decision-making patterns and budget indicators
2Build Your Targeting Layers
Layer targeting criteria to filter out unqualified prospects while maintaining sufficient reach.
- Start with a company list, or company size plus industry if you don't have one
- Add job titles for the people who sign off (the main targeting layer)
- Don't stack job function or seniority on top: LinkedIn ORs them with job titles, which widens the audience
- Add exclusions gradually as the demographics report shows wasted clicks (wrong titles, competitors, existing clients, job seekers)
3Test, Measure, and Refine
Start narrow, measure results, then expand what works and eliminate what doesn't.
- Launch with smaller budgets to test targeting accuracy
- Track cost-per-lead AND lead qualification rates
- Double down on winning audience segments
- On Meta, create lookalike audiences from your best customers (LinkedIn discontinued lookalikes in February 2024)
Platform-Specific Targeting Best Practices
LinkedIn Targeting
- Job Titles: Use specific titles, not generic ones✓ "Operations Director" not "Manager"
- Company Size: Use employee count ranges✓ 51-200 employees for mid-market focus
- Company Lists: Upload your named target companies, then filter by job titles✓ Needs 300+ matched members to deliver
Facebook Targeting
- Interests: Use business-related interests✓ "Business management" + "Industrial equipment"
- Behaviours: Target business decision makers✓ "Small business owners" + "Frequent business travellers"
- Lookalikes (Meta only): Use customer lists for expansion✓ 1-2% lookalike of your best customers
