Most UK restaurants spend £500-£2,000 monthly on marketing with no clear understanding of what's working. That's not marketing—that's gambling. This guide shows you how to track, measure, and optimize every pound spent to maximize your return on investment.

The Essential Marketing Metrics Every Restaurant Owner Must Track

Cost Per Acquisition (CPA)

How much you spend to get one new customer

CPA = Total Marketing Spend ÷ New Customers

Customer Lifetime Value (CLV)

Total revenue from a customer over time

CLV = Avg Order × Visit Frequency × Lifespan

Marketing ROI

Revenue generated per pound spent

ROI = (Revenue - Cost) ÷ Cost × 100

Conversion Rate

Percentage of visitors who book/order

Conversion = Bookings ÷ Website Visits × 100

Golden Rule: If your Customer Lifetime Value is higher than your Cost Per Acquisition, your marketing is profitable. Aim for CLV to be at least 3x your CPA.

5 Quick Wins to Improve Marketing ROI

1. Cut Underperforming Channels Immediately

Track which marketing channels bring customers. If Facebook ads cost £15 per booking but Instagram brings bookings at £6, shift budget to Instagram.

Action: Review last 90 days. Kill bottom 20% of spending.

2. Double Down on What Works

Once you identify high-ROI channels, increase spending there. If Google ads return £4 for every £1 spent, spend more on Google.

Action: Allocate 70% of budget to top performers.

3. Optimize Your Google My Business

GMB is free and often delivers better ROI than paid ads. Complete profile, post weekly, respond to reviews, add photos.

Action: 30 minutes weekly = unlimited free visibility.

4. Implement Booking Attribution Tracking

Ask every customer "How did you hear about us?" Use unique phone numbers or promo codes for different campaigns.

Action: Set up tracking this week.

5. Focus on Customer Retention

Acquiring new customers costs 5x more than retaining existing ones. Email marketing to past customers has 10-40x better ROI than paid ads.

Action: Start collecting email addresses today.
