Small business owners ask us this question constantly. We run both channels for clients, and we have a direct answer. The right platform isn’t determined by which one is “better.” It’s determined by whether your customers are already searching for what you sell.
The Core Difference — Demand Capture vs. Demand Generation
This is the framework that makes every other comparison in this article make sense.
Google Ads: meeting customers who are already looking
Someone who types “emergency roof repair near me” at 8pm is a customer right now. They have a problem, they’re searching for a solution, and they’re comparing providers. Google Ads put your business in front of that person at the exact moment of intent. You’re not creating demand — you’re capturing it.
This is the structural advantage of paid search. The click costs more than a Facebook impression, but the person clicking has already decided to buy. You’re not convincing them to want something. You’re competing for the business they’ve already decided to spend.
Facebook Ads: creating demand for things people don’t know they need yet
Someone scrolling Facebook didn’t open the app to find a contractor. They’re looking at photos from their cousin’s wedding, checking local news, and watching a video someone shared. Your ad interrupts that experience. Done well, it plants a seed — “oh, I’ve been meaning to fix that fence” or “I should look into that.” Done poorly, it’s ignored.
Facebook is not a search engine. It’s an interruption channel. That’s not a knock against it — some products and services are perfectly suited to interruption marketing. But the sales process is different, and the attribution is noisier.
Why this distinction determines everything else
The demand-capture vs. demand-generation distinction determines your expected cost-per-lead, your follow-up process, your required ad creative, and your measurement approach. Google leads are closer to conversion. Facebook leads require more nurturing. Neither is universally better — they’re different tools for different jobs.
When Google Ads Wins for Small Businesses
Service businesses with high-intent searches
If people search for your service category actively — plumbers, HVAC technicians, dentists, injury lawyers, roofers, pest control — Google Ads is typically the stronger channel. These are high-intent searches by definition: someone searching “emergency HVAC repair” is not browsing, they’re buying.
Home services businesses generate 65% of their digital leads from Google Search (combined Local Services Ads and paid search) versus under 15% from Facebook (BrightLocal research). That gap exists because the purchase decision is made before the search, not during the ad scroll.
Products people search for with specific intent
If you sell something with a recognizable product name or category — “custom wedding invitations,” “standing desk,” “leather boots” — paid search captures buyers who already know what they want. Pairing strong Google Shopping or search ads with specific landing pages produces predictable cost-per-acquisition.
Local businesses where “near me” traffic is high
“Near me” searches have grown 150% faster than traditional local searches over the past five years (Think with Google). A local restaurant, auto repair shop, or retail store showing up on Google when someone nearby searches for their category is as close to guaranteed-intent traffic as advertising gets.

When Facebook Ads Wins for Small Businesses
Visually driven products with broad appeal
Home décor, clothing, food products, jewelry, gifts — these categories have a visual hook that works in an interruption context. Facebook’s visual feed and Instagram placements let you show the product in a lifestyle context. Someone who wasn’t searching for a specific candle brand can see one in a beautifully styled photo and convert.
The decision: if your product requires seeing it to want it, Facebook has advantages Google can’t match.
Offers that require explanation or demonstration
Some services and products need context before they convert. A new SaaS tool, a coaching program, an unusual service category — these don’t have people actively searching because the category isn’t well-known yet. Facebook lets you reach a targeted demographic, explain the offer through creative and copy, and build intent through repeated exposure.
This is demand generation: you’re creating awareness that turns into search behavior later. Often, Facebook awareness campaigns produce Google search volume — people see the Facebook ad, don’t click, but search for the brand name later.
Retargeting past visitors and warm audiences
Retargeting — showing ads to people who’ve already visited your website or engaged with your social content — works well on both platforms. Facebook’s retargeting still outperforms for warm audiences, particularly for product businesses where the purchase cycle requires multiple touchpoints. Retargeting ads generate 70% higher conversion rates than cold prospecting ads (Criteo).
A $200/month Facebook retargeting campaign targeting website visitors from the past 30 days is one of the highest-ROI uses of a small Facebook budget.
Building brand awareness before search volume exists
If you’re launching something new in your local market, Google Ads may not have the search volume to be viable yet. A $500/month Facebook budget can reach 45,000–90,000 local users with awareness content. The same budget on Google search might generate 150–200 clicks — but only if those searches exist.
Facebook builds the audience that eventually generates the searches.
Cost Comparison — What You Actually Pay Per Lead
Google Ads CPC benchmarks by industry
Average cost-per-click across all industries on Google search: $2.69 (WordStream, 2024). But averages mask the industry variation that matters for your budget decision:
- Home services (HVAC, plumbing, electrical): $6–$12/click
- Legal: $5–$15/click on general terms, $40–$60/click on competitive terms like “car accident lawyer”
- Dental: $3–$8/click
- SaaS/B2B: $5–$15/click
- ecommerce (general): $1.50–$4/click
Facebook CPM and estimated cost-per-lead benchmarks
Facebook charges on a CPM (cost per thousand impressions) basis, averaging $11.20 across industries (2024). Converting that to cost-per-lead requires knowing your click-through rate and landing page conversion rate — two variables that vary significantly by industry and creative quality.
Rough cost-per-lead benchmarks: home services on Facebook $15–$50/lead, legal $50–$100/lead. These look cheaper than Google on the surface. The difference is lead quality. Google leads from someone who searched “emergency plumber” close at a higher rate than Facebook leads from someone who saw a plumbing ad while scrolling.
Average cost-per-lead on Google for legal: $135. On Facebook: $72 — but Google leads close at significantly higher rates (WordStream legal benchmarks). The right comparison is cost-per-closed-job, not cost-per-lead.
The conversion math: cheaper clicks don’t mean cheaper leads
A $2 Facebook click that converts at 1% produces a $200 cost-per-lead. A $10 Google click that converts at 8% produces a $125 cost-per-lead. Click cost alone tells you almost nothing about which channel is more efficient.
Run the math with your actual close rate and job value. Use cost-per-closed-customer as your decision metric. For help setting up that measurement framework, see our guide on measuring digital marketing ROI for small business.
What Changes With a Limited Budget
Under $1,000/month: why you probably can’t do both well
Running both channels at $500 each gives you a budget that’s too small to generate enough data on either platform to optimize effectively. Google Ads on $500/month in a competitive market might produce 50–80 clicks per month — not enough volume to test ad copy, landing pages, or bidding strategies.
On Facebook, $500/month produces enough impressions to get started, but split between prospecting and retargeting, creative testing, and multiple ad sets, you’re spreading thin.
The honest answer: pick one channel, fund it adequately, and learn it thoroughly before expanding. Most SMBs should start with the channel where their customers have the strongest existing demand.
The case for going deep on one channel before expanding
A business that masters Google Ads at $1,500/month — with tested keywords, optimized landing pages, and conversion tracking configured correctly — knows its cost-per-lead and can scale predictably. That’s a much stronger position than running two mediocre campaigns at $750 each.
Go deep. Then expand.
How to allocate if you must split the budget
If you’re already running both and need to split: put 70% on the channel with a lower current cost-per-lead and clearer ROI. Use the remaining 30% on the other channel for retargeting only — the highest-efficiency use of a small secondary budget.
Platform Limitations to Know Before You Spend
Facebook’s iOS 14+ attribution problem
Apple’s App Tracking Transparency (iOS 14, 2021) broke a significant portion of Facebook’s ability to track conversions that happen on websites after a Facebook ad click. Advertisers lost visibility into an estimated 30–60% of conversion events (Meta’s own estimates). Facebook’s reported results became less reliable, not worthless — but the discrepancy between what Facebook reports and what actually happened grew substantially.
This doesn’t make Facebook Ads worthless. It makes their reported results less reliable. You now need to supplement Facebook’s in-platform reporting with your own tracking: UTM parameters in Google Analytics, server-side event tracking, and honest comparison of what Facebook reports versus what your CRM or call log shows.
Facebook’s targeting also lost precision post-iOS 14. Interest and behavior targeting is estimated to be 20–30% less accurate than pre-2021 data suggested.
Google’s Smart Campaign defaults and performance data
Google defaults new advertisers toward Smart Campaigns, which hide most performance data behind a simplified interface. Smart Campaigns don’t give you access to the Search Terms report — the single most important diagnostic tool in Google Ads. A business running Smart Campaigns may be spending efficiently or wastefully, with no way to tell the difference.
Standard search campaigns are more complex to set up but give you the data needed to actually manage performance.
The Honest Answer for Most SMBs
If people actively search for your service or product category in your local market, start with Google Ads. The intent is built in. The sales process is shorter. The attribution is cleaner.
If you sell something that benefits from visual demonstration, or if you serve a local market where search volume for your category is thin, Facebook’s awareness and retargeting tools can build the pipeline that eventually becomes search traffic.
For most local service businesses — HVAC, plumbing, legal, dental, home improvement — Google Ads is the clearer starting point. The data supports it. The intent model supports it.
When clients ask us to recommend one: we ask first whether their service has meaningful search volume in their local market. If yes, Google Ads management is our recommendation. If no — or if they’re running a product or brand that needs awareness-building — we look at social media management and paid social as the primary channel.

Frequently Asked Questions
Should I run Google Ads and Facebook Ads at the same time? Only if your budget is large enough to fund both adequately — typically $2,000+/month total. Below that, you’re better off choosing one channel and running it well. Split budgets below a meaningful threshold produce too little data on each platform to optimize effectively.
Which platform has a lower cost per lead for local service businesses? Google Ads typically produces a lower cost-per-closed-customer for local service businesses with high-intent search categories. Facebook may show a lower cost-per-lead, but those leads close at lower rates. Run the math through to cost-per-closed-job before declaring a winner.
Is Facebook Ads still worth it after the iOS 14 changes? Yes, with adjusted expectations. Facebook’s reported conversion numbers are less reliable, but the ads still reach real people. Use UTM parameters and GA4 to cross-reference what Facebook reports versus what your website analytics show. Retargeting on Facebook is still highly effective — the attribution loss is more pronounced on cold prospecting.
Can I start with a $500/month budget on Google Ads? Yes, but with realistic expectations. At $500/month in a competitive service niche with $8–$12 CPCs, you’ll generate 40–60 clicks per month. That’s enough to test conversion tracking and message match. It’s not enough to draw conclusions about bidding strategies or run meaningful A/B tests.
Why do Facebook Ads show higher conversions than I actually see in my business? View-through conversions (counted when someone sees an ad but doesn’t click, then converts later through another channel), reporting window differences (Facebook often uses a 7-day click + 1-day view window), and post-iOS 14 modeled data all contribute. What Facebook reports and what actually came from Facebook advertising can differ significantly. Cross-reference with UTM-tracked GA4 data for a more accurate picture.
What type of small business gets the best results from Google Ads? Local service businesses with high-intent search categories: HVAC, plumbing, legal, dental, pest control, roofing, locksmith, auto repair. These categories have people actively searching for help — Google puts your business in front of that intent at the moment it exists.
How do I decide between Google search ads and Facebook ads for a new business? Check search volume in your specific market first. Use the Google Keyword Planner with your service area targeted and look at monthly search volume for your core service terms. If that volume is above 500 searches/month in your city, Google Ads is the viable starting point. If the volume is thin or your service category isn’t commonly searched, Facebook is the awareness channel to build demand before search volume develops.
