The Fundamental Difference
Google Ads: Capturing Demand
Google Ads shows your ad to people who are actively searching for your product, service, or a solution to their problem. They have intent — they're in the market, comparing options, or ready to buy. You're meeting demand that already exists.
Example: Someone searches "plumber emergency Sydney." They need a plumber right now. A Google Ad puts your plumbing business at the top of their search results at the exact moment they need you.
Facebook/Meta Ads: Creating Demand
Facebook and Instagram ads show your ad to people who match a target profile — demographics, interests, behaviours — while they're scrolling their feed. They're not searching for your product; you're interrupting their browsing to introduce them to it. You're creating demand that didn't exist 5 seconds ago.
Example: Someone is scrolling Instagram. They see an ad for a new skincare product. They weren't looking for skincare, but the ad is compelling enough that they click through and buy.
When Google Ads Is the Better Choice
People Are Already Searching for What You Sell
If your product or service has existing search demand (people actively type it into Google), Google Ads captures that demand at its highest intent. This is ideal for:
- Service businesses (plumbers, lawyers, dentists, accountants)
- "Solution-aware" products (people know the category — "running shoes," "CRM software")
- Emergency or urgent services
- Local businesses where location-based search is dominant
- B2B services where buyers research before purchasing
Your Product Needs No Explanation
If people already understand what you sell and are comparing providers, Google Ads puts you in the consideration set. Products that need education or discovery are better suited to Facebook Ads.
You Have a High Average Order Value
Google Ads clicks can be expensive ($5–$50+ depending on industry). If your product sells for $20, the cost per click may not be sustainable. But if your average sale is $500 or your customer lifetime value is $5,000, the maths works even at high CPCs.
You Want Immediate, Predictable Leads
Google Ads campaigns can go live in a day and generate leads immediately. Budget scales roughly linearly — spend more, get more leads (within your market's search volume). It's the most predictable paid acquisition channel.
When Facebook/Meta Ads Is the Better Choice
Your Product Is Visual or Lifestyle-Driven
Products that sell through imagery — fashion, homewares, food, beauty, fitness, travel — perform exceptionally well on Instagram and Facebook. The visual ad format showcases the product in a way text-based Google Search ads can't.
You Need to Create Awareness Before Purchase
If people don't know your product category exists, or don't know they need it, Facebook Ads introduces them. This is essential for:
- New or innovative products
- DTC (direct-to-consumer) brands
- Products people didn't know they wanted until they saw them
- Upcoming events, launches, or promotions
You Have Strong Creative Assets
Facebook and Instagram are creative-led platforms. Strong imagery, compelling video, and authentic UGC content drive performance. If you can produce scroll-stopping creative, Meta Ads will reward you.
You Want to Reach a Specific Demographic
Meta's audience targeting lets you reach people based on demographics, interests, and behaviours. While Meta has reduced some detailed targeting options, its algorithm is extremely effective at finding people likely to convert — particularly through Advantage+ campaigns and lookalike audiences.
You're an Ecommerce Brand
For ecommerce, Meta Ads excels at:
- Product discovery — introducing your brand to new customers
- Dynamic product retargeting — showing people the exact products they viewed
- Full-funnel campaigns — awareness → consideration → conversion
- Scaling spend — Meta's algorithm can scale budgets efficiently with the right creative
Cost Comparison
Google Ads Costs
- Average CPC (Search): $1–$10 for most industries; $10–$50+ for competitive industries (legal, insurance, finance)
- Average CPC (Shopping): $0.30–$3
- Average CPC (Display): $0.50–$3
- Average CPC (YouTube): $0.05–$0.30 (cost per view)
Meta Ads Costs
- Average CPM (cost per 1,000 impressions): $8–$25
- Average CPC: $0.50–$3 for most industries
- Average CPA (cost per acquisition): Varies wildly by industry and offer, but typically $10–$80 for ecommerce, $20–$150 for lead generation
Which Is Cheaper?
Meta Ads generally have lower CPCs than Google Ads (Search). But cost per click isn't the right comparison — cost per acquisition (CPA) or return on ad spend (ROAS) is. Google Ads clicks are more expensive but higher intent, so they often convert at a higher rate. A $10 Google click that converts at 10% = $100 CPA. A $1 Meta click that converts at 1% = $100 CPA. Same cost per customer.
Performance Comparison by Business Type
Ecommerce
Google Ads: Strong for Google Shopping (product listings), branded search, and retargeting. Captures people searching for specific products.
Meta Ads: Strong for product discovery, reaching new customers, and retargeting (dynamic product ads). Better for brand building and top-of-funnel.
Recommendation: Use both. Google Shopping for demand capture, Meta for demand creation and retargeting. Most successful ecommerce brands run both channels.
Local Service Businesses
Google Ads: The dominant channel. Local search intent ("plumber near me," "dentist [suburb]") is perfectly matched by Google Search and Local Service Ads.
Meta Ads: Less effective for urgent, immediate-need services. Can work for awareness and brand building in a local area, but rarely the primary lead channel.
Recommendation: Start with Google Ads. Add Meta Ads for brand awareness and seasonal promotions if budget allows.
B2B Lead Generation
Google Ads: Strong for capturing high-intent searches. Works best when buyers search for specific solutions or services.
Meta Ads: Less effective for most B2B. LinkedIn Ads are typically a better social channel for B2B because of professional targeting.
Recommendation: Start with Google Ads. Consider LinkedIn over Meta for social advertising. Meta can work for B2B retargeting and content promotion.
DTC/Brand-Led Products
Google Ads: Limited if people aren't searching for your brand or product category yet. Branded search campaigns protect your name.
Meta Ads: The primary growth channel for most DTC brands. Prospecting, creative testing, and scaling all happen on Meta.
Recommendation: Start with Meta Ads. Add Google Ads for branded search and Shopping once you have product awareness.
SaaS
Google Ads: Effective for capturing searches like "[competitor] alternative" and "[solution] software."
Meta Ads: Can work for retargeting and content promotion. Less effective for cold prospecting in B2B SaaS.
Recommendation: Start with Google Ads Search. Consider LinkedIn for social. Meta for retargeting.
The Best Approach: Use Both
For most businesses with sufficient budget, the ideal approach uses both Google Ads and Meta Ads:
- Google Ads captures demand — reach people actively searching for your product or service
- Meta Ads creates demand — reach new audiences who match your customer profile
- Both retarget — Google and Meta both offer retargeting to re-engage website visitors
- Data flows between them — customer lists from one channel improve targeting on the other
The channels complement each other. Google Ads is strongest at the bottom of the funnel (high intent, ready to buy). Meta Ads is strongest at the top (awareness, discovery). Together, they cover the full customer journey.
How to Decide
If you can only start with one, answer these questions:
- Are people searching for what you sell? Yes → Google Ads. No → Meta Ads.
- Is your product visual? Yes → Meta Ads is a strong option. No → Google Ads.
- Do you need leads today? Yes → Google Ads (faster to results). No → Either works.
- Is your average order value high enough for Google CPCs? No → Meta Ads (lower CPCs).
- Do you have strong ad creative (images/video)? Yes → Meta Ads. No → Google Ads (text ads).

Frequently Asked Questions
Can I run both Google Ads and Facebook Ads at the same time?
Yes, and most businesses should. The two channels serve different purposes and complement each other. Google captures high-intent search traffic while Meta creates awareness and retargets. Running both gives you full-funnel coverage.
Which has a better ROI — Google Ads or Facebook Ads?
It depends on your business. Google Ads typically has higher intent and higher conversion rates but higher CPCs. Meta Ads has lower CPCs but requires more creative investment and typically lower intent. The right comparison is cost per customer or ROAS, not cost per click.
How much budget do I need to test each platform?
For meaningful testing, we recommend at least $2,000–$3,000/month in ad spend per platform, plus management fees. This gives you enough data to evaluate performance within 30–60 days. Below that, you may not generate enough conversions for reliable conclusions.
Do I need different landing pages for Google Ads and Facebook Ads?
Often, yes. Google Ads traffic has high purchase intent — they searched for something specific. Your landing page should deliver exactly what they searched for. Facebook Ads traffic has lower intent — they were interrupted mid-scroll. Your landing page needs to re-engage them and build the case from scratch. Landing page optimisation helps with both.
