Google Ads vs Facebook Ads: Budget Split Guide

Why Budget Split Matters for Contractors

Google Ads and Facebook Ads serve completely different purposes. Google captures the person actively searching "emergency plumber near me" at 2 a.m. on a Sunday; Facebook shows your roofing ad to a homeowner scrolling through their feed who may need repairs in 3–6 months. One is high-intent (expensive), the other is awareness-building (cheap). Most contractors waste money by treating them the same or choosing one entirely.

A split budget strategy leverages both: Google drives immediate, high-converting leads; Facebook fills your pipeline and retargets searchers who didn't call. The optimal split depends on your trade, seasonality, and market size. A plumber in a large metro running both platforms at 40% Facebook / 60% Google might spend $4,000/month ($1,600 Facebook, $2,400 Google) and pull 35–50 leads. A landscaper in the same metro using 60% Facebook / 40% Google during off-season ($2,000/month: $1,200 Facebook, $800 Google) might pull 40–60 leads at lower cost because awareness-building scales cheap in slow months.

Google Ads Cost vs Facebook Ads: Real Numbers

The cost difference is stark. Google Ads for contractors average $15–$35 per click (CPC) depending on trade and metro. Facebook averages $1–$3 per click. On a $2,000 monthly budget:

• Google only ($2,000): 57–133 clicks; roughly 8–15 leads (assuming 15% conversion from click to lead call)
• Facebook only ($2,000): 667–2,000 clicks; roughly 40–80 leads (assuming 5–10% conversion because it's colder traffic)
• Split 50/50 ($1,000 each): 57–133 Google clicks + 333–1,000 Facebook clicks; roughly 24–48 leads total

The confusion comes here: more Facebook clicks does NOT mean more revenue. Google clicks convert higher because the person is already in-market. An electrician gets 1 call from 5 Google clicks but needs 15 Facebook clicks for the same call. So budget allocation must match your lead demand and conversion funnel.

Real example: Johnson's HVAC in Charlotte, NC (metro pop. 1.4M). Summer (high intent) budget: $4,000/month split 35% Facebook ($1,400) / 65% Google ($2,600). Google CPC averages $22, Facebook CPC averages $2. Johnson's pulls ~118 Google clicks (17 leads at 15% conv.) and ~700 Facebook clicks (21 leads at 3% conv. — Facebook is colder). Total: ~38 leads, average cost-per-lead $105. Winter (low intent) budget: same $4,000, flipped to 65% Facebook ($2,600) / 35% Google ($1,400). Google CPC stays $22 (~63 clicks, 9 leads), Facebook CPC drops to $1.50 (~1,733 clicks, 52 leads at 3% conv.). Total: ~61 leads, average CPL $65. Seasonality cuts CPL 38% by rebalancing.

Seasonality: When to Shift Your Budget Split

The biggest mistake contractors make is running a static split year-round. Demand is NOT flat.

Summer (May–August): High-intent season. Homeowners need AC repair, roof leaks, siding damage. Google search volume for "HVAC repair near me" spikes 40–60%. Run 60/40 or even 70/30 Google-heavy. Your Google CPC actually drops slightly ($18–$22 vs. $25+ in winter) because intent is so clear that relevance score climbs. Example: A roofer in Denver pulls 45 leads in July on a $3,000 budget split 65% Google ($1,950) / 35% Facebook ($1,050). Google CPC = $20, Facebook CPC = $1.80.

Fall (September–October): Maintenance season. Still decent intent (gutter cleaning, furnace prep, siding touch-ups). Stay 60/40 or 55/45 Google/Facebook. CPCs begin climbing as search volume plateaus.

Winter (November–February): Low-intent, awareness season. Search volume for non-emergency services collapses. Facebook dominates because you're building pipeline for spring jobs. Flip to 50/50 or even 60/40 Facebook/Google. A landscaper in Minneapolis runs 70% Facebook / 30% Google in January ($2,000/month: $1,400 Facebook, $600 Google) because snow removal searches are flat but spring design consultations are lead-gen fuel. Facebook cost-per-lead drops to $12–$18 because the audience is truly cold and you're just capturing name/number for spring.

Spring (March–April): Pre-surge season. People plan renovations and book contractors. Revert to 55/45 or 50/50. Search intent climbs but hasn't peaked yet.

The 30/70, 40/60, and 50/50 Rules: Which Works for Your Trade

30% Facebook / 70% Google: Emergency-driven trades. Plumbers, electricians, locksmiths, emergency tree service. People search when they need you NOW. Google captures 70% of intent; Facebook builds awareness for 30%. Cost-per-lead from Google: $25–$40. Facebook: $12–$20. Monthly budget example ($3,000): $900 Facebook, $2,100 Google. Expected leads: 12–18 Facebook + 52–84 Google = 64–102 leads. This split works year-round for emergency trades.

40% Facebook / 60% Google: Seasonal trades with year-round demand. HVAC (mixed emergency + maintenance), roofing (year-round repairs + spring/fall projects), plumbing (emergency + maintenance), general contracting. Most contractors default here. It balances immediate revenue (Google) with pipeline-building (Facebook). Monthly budget ($4,000): $1,600 Facebook, $2,400 Google. Expected leads: 32–64 Facebook + 68–160 Google = 100–224 leads. This split adjusts by season: increase Facebook in winter, increase Google in summer.

50% Facebook / 50% Google: Image-driven and seasonal trades. Landscapers, pool builders, fence companies, painters, roofing (when focused on new builds/cosmetics). Facebook's visual strength wins. You need equal parts immediate leads (Google: "new deck cost near me") and project inspiration (Facebook: "see our finished decks"). Monthly budget ($2,500): $1,250 each. Expected leads: 42–100 Facebook + 35–83 Google = 77–183 leads. This split is more volatile; shift 10–15 points toward Facebook in off-season.

60% Facebook / 40% Google: Build-in-advance trades and offline conversion models. Solar companies, pool builders (consultations booked weeks ahead), home improvement financing. You need volume at the top of funnel because closing takes 4–12 weeks. Monthly budget ($3,000): $1,800 Facebook, $1,200 Google. Expected leads: 60–180 Facebook + 34–80 Google = 94–260 leads. Facebook CPL is $10–$15; Google is $18–$28. Higher volume, longer sales cycle.

Real Example: Budget Split in Action

Martinez Electrical Services, Phoenix, AZ (metro pop. 1.7M)

Scenario: July (high-intent season), $2,500 budget.

• Split chosen: 35% Facebook ($875) / 65% Google ($1,625)
• Google: CPC = $20. Clicks = 81. Conversion (click to lead call) = 18%. Leads = 15.
• Facebook: CPC = $1.75. Clicks = 500. Conversion (click to lead call) = 4% (lower intent, many tire-kickers). Leads = 20.
• Total leads: 35. Cost-per-lead: $71.

Scenario: January (low-intent season), same $2,500 budget, different split.

• Split chosen: 60% Facebook ($1,500) / 40% Google ($1,000)
• Google: CPC = $28 (lower search volume, higher competition per searcher). Clicks = 35. Conversion = 18%. Leads = 6.
• Facebook: CPC = $1.20 (audience size is massive, competition is lower per impression). Clicks = 1,250. Conversion = 2.5% (very cold, maintenance-focused). Leads = 31.
• Total leads: 37. Cost-per-lead: $67.

Same total leads, slightly better CPL in winter by rebalancing. The split shifted 25 percentage points toward Facebook because Google intent collapsed.

When Google Ads Win: Immediate Revenue Trades

Run a higher Google allocation (55–70%) if:

• Your service is emergency-driven or urgent. Plumber, electrician, locksmith, emergency tree removal, HVAC emergency repair. People search NOW. Google search volume for "emergency plumber" is 12–15x higher than "plumber near me." You capture that urgency or lose the call to a competitor who does.
• Your average job value is $1,500+. Higher revenue per lead means you can afford higher CPC. A solar installer at $8,000 average job can spend $50–$80 per Google lead and still profit. A handyman at $300 average job cannot.
• Your market is medium-to-large metro (pop. 500K+). Big cities have high Google search volume but also high Facebook audience overlap and saturation. Google helps you differentiate.
• You have low audience fatigue. If you've been running Facebook for 6+ months, audiences tire and CPL climbs. Shift budget to Google to reset.

When Facebook Ads Win: Pipeline and Awareness Trades

Run a higher Facebook allocation (50–70%) if:

• Your service is planned/consultative. Landscaper, pool builder, kitchen remodeler, solar installer, fence company, roofer (new construction/cosmetic). People don't search urgently; they scroll social media and get inspired. Facebook CPL is $8–$18; Google is $35–$60 for the same job type because intent is lower on Google (you're competing with general "home remodeling" searches).
• Your average job value is $2,000–$15,000+ with a long sales cycle. You need volume at the top of the funnel. Facebook delivers 3–5x more clicks for the same spend. A 20% close rate on 100 leads beats a 40% close rate on 30 leads.
• Your market is small-to-medium metro (pop. 50K–400K). Google search volume is thin; Facebook audience reach is still broad. Facebook CPL stays low; Google CPL climbs because fewer searches occur.
• You're in off-season or low-demand months. January, November, February for most trades. Facebook audience costs drop 30–40% because overall platform competition decreases. Use it to fill your pipeline.
• You run retargeting campaigns. Retargeting Facebook website visitors or lead form abandoners on Facebook costs $0.50–$1.50 per click (vs. $15–$30 on Google Search). Retargeting is where Facebook generates 300–500% ROI for contractors.

When a Split Budget Does NOT Work

Be honest: a split-budget strategy fails in these situations:

• You have less than $1,000/month total spend. Splitting compounds inefficiency. Choose ONE platform, master it to $2,000/month, then split. Running $300 Google + $200 Facebook means neither account gathers enough data to exit the learning phase (Facebook needs ~50 conversions; Google needs clear keyword performance). You'll burn $500 and see nothing but noise.
• Your product has zero seasonality and you need leads every single day. Emergency plumbing in a metro where calls are constant? Run 70% Google year-round. Retargeting on Facebook at 30% will fatigue your audience in 4–6 weeks. You need consistent high-intent traffic to scale.
• Your market is extremely small (rural, pop. <50K). Facebook audience size collapses. Running Facebook ads in a town of 15,000 means you'll exhaust the audience in 2 weeks (frequency climbs to 5–10x, CPL doubles to $30–$50). Stick with Google Local Services Ads or Google Search if available. See Facebook ads for rural contractors.
• Your customer acquisition cost (CAC) from referral is lower than any paid channel. If your plumbing referrals cost you $20/lead (5% referral fee on $400 jobs) and Facebook/Google split gives you $60–$90 CPL, paid ads lose. Reinvest in referral systems, not ads.
• You have no CRM or lead follow-up system. A split budget generates 50–100+ leads/month. If you're writing them down in a notebook and calling a week later, conversion will be 2–5% and your CPL will feel inflated. Implement a CRM, set up CRM integration for Facebook leads, and track conversion properly before splitting spend.
• Your Google Ads account is brand new (less than 2 weeks live). Google's learning phase takes 10–14 days to stabilize. Facebook's is 7–10 days. Starting both simultaneously means both are noisy for the first 14 days. Pick one, run it for 2 weeks, then add the second.

How to Rebalance: Track, Test, Adjust

Don't set your split and forget it. Review weekly.

1. Pull CPL for each platform daily. Use a simple spreadsheet: Date | Platform | Spend | Leads | CPL. After 7–10 days, you'll see a trend. Google trending at $50 CPL? Facebook at $15? Time to shift 10% from Google to Facebook for the next week.
2. Test a 10–15% shift for 7–10 days. Don't flip from 60/40 to 40/60 overnight. Move 10 percentage points: 60/40 → 50/50. Wait 10 days. If CPL improves, shift another 10 points. If CPL worsens, revert.
3. Watch for creative fatigue on Facebook. If Facebook CPL climbs from $12 to $22 over 3 weeks without ad changes, audience fatigue is hitting. Pause Facebook for 5–7 days, shift budget to Google, then return to Facebook with new creative. See creative refresh schedules.
4. Adjust for seasonality in advance. Don't wait for January data to shift off Google. In November, start increasing Facebook 5–10 percentage points each week. By December, you're at your winter split before demand collapses.

Tools to Monitor and Automate Your Split

Leadria's AI handles copy and targeting, but you own the budget allocation. Use these freely available or low-cost tools to track your split:

• Google Ads Editor (free): Adjust daily budgets across campaigns. If you have a "Google Search – Plumbing" campaign and a "Google Search – Maintenance" campaign, lower one by $200 and raise the other to test allocation.
• Facebook Ads Manager (free): Set daily budgets per campaign. Same logic: if your "Retargeting" campaign CPL is $8 and "Cold Audience" is $35, shift spend from Cold to Retargeting.
• Spreadsheet tracking (free): Google Sheets, one row per day. Platform | Spend | Impressions | Clicks | Conversions (leads) | CPL. Simple, searchable, and it forces you to look at data daily.
• Google Analytics 4 (free): Connect Google Ads and Facebook to GA4. Use conversion tracking to compare platform performance end-to-end (not just clicks, but actual customer behavior).

Most contractors under-invest in this monitoring. Spend 15 minutes daily checking spend and CPL by platform. That 15 minutes will save you $500–$2,000/month in wasted budget.

Final Benchmark: The 40/60 Default and When to Break It

If you're starting a split-budget strategy, begin with 40% Facebook / 60% Google. This allocation works for ~70% of contractor trades year-round. After 2–3 weeks of data:

• If Facebook CPL is 30–50% lower than Google, shift to 50/50 or 55/45.
• If Google CPL is below $30 and Facebook is above $20, shift to 35/65 or 30/70.
• If you're in off-season, shift 15 points toward Facebook.
• If you're in peak season, shift 15 points toward Google.

Track this monthly. The best contractors don't guess; they spend 30 minutes each week reviewing CPL by platform and adjusting budget allocation. Your split in July should look different from January. If it doesn't, you're leaving money on the table.
