The Ultimate Question: Google or Facebook?

You have a marketing budget and need to decide: Google Ads or Facebook Ads? The truth is, they serve different purposes, and understanding these differences is crucial for maximizing your ROI. This guide breaks down exactly when to use each platform based on real data from 200+ local service businesses.

Understanding the Fundamental Difference

Google Ads: The "I Need This Now" Platform

Google Ads captures high-intent searchers actively looking for your services. When someone types "emergency plumber near me," they have a problem right now and need an immediate solution.

Key Characteristics:

High intent = High conversion rates (30-50% for service businesses)
Higher cost per click (£2-15 depending on industry)
Immediate results
Bottom-funnel marketing

Facebook Ads: The "I Didn't Know I Needed This" Platform

Facebook Ads interrupt people during leisure time with offers they might be interested in based on demographics, interests, and behaviors.

Key Characteristics:

Lower intent = Lower conversion rates (5-15% typical)
Lower cost per click (£0.50-3)
Longer sales cycle
Top and middle-funnel marketing

Cost Comparison: Real Numbers

Google Ads Pricing (UK Local Services 2025):

Plumbing: £5-12 per click, £40-80 cost per lead
HVAC: £6-15 per click, £50-100 cost per lead
Roofing: £8-20 per click, £70-150 cost per lead
Electrical: £4-10 per click, £35-70 cost per lead
Locksmith: £3-8 per click, £25-50 cost per lead

Cost per click: £0.80-2.50 across all industries
Cost per lead: £15-40 (but lower quality leads)
Cost per conversion: £80-200 (accounting for lower conversion rates)

When to Use Google Ads

✅ Perfect for Google Ads:

Emergency Services: Plumbing, electrical, locksmith, towing
High-Intent Searches: People actively researching solutions
Local Services: "Near me" searches convert exceptionally well
Immediate Needs: Repairs, installations, urgent consultations
High Ticket Services: ROI justifies higher cost per click

❌ Not Ideal for Google Ads:

Low-ticket services (under £200)
Services with long consideration periods
Brand building campaigns
Very limited budgets (under £500/month)

When to Use Facebook Ads

✅ Perfect for Facebook Ads:

Brand Awareness: Introduce your business to the community
Seasonal Promotions: HVAC tune-ups, lawn care packages
Maintenance Services: Services people don't actively search for
Remarketing: Re-engage website visitors who didn't convert
Visual Services: Landscaping, renovations, cosmetic improvements

❌ Not Ideal for Facebook Ads:

Emergency services
Services requiring immediate action
Highly technical B2B services
Services with very specific keywords

ROI Analysis: Which Performs Better?

Google Ads ROI:

Plumbing Company Example:

Monthly Budget: £1,500
Leads Generated: 25-35
Conversion Rate: 40%
New Customers: 10-14
Average Job Value: £350
Revenue: £3,500-4,900
ROI: 133-227%

Facebook Ads ROI:

Plumbing Company Example:

Monthly Budget: £1,500
Leads Generated: 50-75
Conversion Rate: 12%
New Customers: 6-9

Conclusion

Google Ads and Facebook Ads aren't competitors—they're complementary tools serving different purposes. Google captures demand that already exists; Facebook creates demand by building awareness. For most local service businesses, Google Ads delivers better immediate ROI, but incorporating Facebook Ads for brand building and remarketing creates a complete marketing system that dominates your local market.

Start with Google Ads to generate immediate revenue, then layer in Facebook Ads to build long-term brand equity. This hybrid approach consistently outperforms single-channel strategies by 40-60%.
