Understanding Your Numbers: The Marketing Metrics Every UK Business Owner Must Know

Why Most Business Owners Fly Blind

Running a business without tracking your key metrics is like driving from London to Edinburgh with no map and no road signs.

You don't need a degree in data analytics. You need to track eight numbers, understand what they mean, and know how to improve them.

The 8 Marketing Metrics That Matter

1. Cost Per Lead (CPL)

Formula: Total marketing spend divided by total number of leads Example: £500 on Google Ads, 20 enquiries = £25 CPL

2. Lead Conversion Rate

Formula: (Customers won divided by total enquiries) x 100 Benchmarks: Trades 40-60%, Professional services 25-40%

3. Customer Acquisition Cost (CAC)

Formula: Total marketing spend divided by new customers acquired Critical: Your CAC must be significantly lower than your Customer Lifetime Value.

4. Customer Lifetime Value (CLV)

Simple formula: Average transaction value x transactions per year x years as customer Example: £200 x 3 x 4 years = £2,400 CLV

5. Website Conversion Rate

Benchmark: 1-5% average; 5-10%+ for optimised sites

6. Return on Ad Spend (ROAS)

Formula: Revenue from ads divided by ad spend Example: £5,000 revenue from £1,000 spend = 5x ROAS

7. Review Score and Volume

• Target: 4.5+ stars on Google (4.7+ is excellent)
• Target: 50+ reviews for credibility

8. Traffic Sources

Knowing which channels drive quality traffic allows you to invest more in what works.
