Key takeaways
- Google Ads wins when buyers already know what they want and are actively searching for it.
- Facebook and Instagram ads win when you need to create demand for something people aren't yet searching for.
- Home services and legal typically get better ROI from Google Ads because of high-intent local search volume.
- E-commerce and lifestyle brands often perform better on Meta because visual product discovery drives impulse purchases.
- Most businesses with a real budget should run both, but in different proportions depending on their sales cycle.
This question comes up in almost every first call with a new advertising client, and the honest answer is that it depends on what your buyer is doing at the moment you want to reach them. Google Ads and Facebook Ads aren't competing versions of the same tool, they solve different problems, and picking the wrong one for your sales cycle is the fastest way to burn a quarter's ad budget with nothing to show for it.
Google Ads shows up when someone is actively searching for a solution. Facebook and Instagram ads show up while someone is scrolling, not looking for anything in particular. That distinction, intent versus interruption, should drive most of your platform decision, with industry and average order value shaping the rest.
Where Google Ads wins
Home services, legal, healthcare, and anything with an urgent or immediate need perform best on Google Ads because the buyer is already looking. Someone searching 'emergency plumber near me' or 'personal injury lawyer consultation' has intent baked in, and search ads convert that intent directly. In our work with home service and legal clients, Google Ads consistently produces lower cost per qualified lead than Facebook for exactly this reason.
- High urgency, high intent categories: plumbing, HVAC, legal, roofing, locksmiths
- Local service businesses with a defined service area
- B2B services with a specific, searchable pain point
- Anything where 'near me' or brand-name searches carry real volume
Where Facebook and Instagram win
E-commerce, real estate listings, hospitality, and lifestyle brands often do better on Meta because the product sells itself visually before the buyer knows they want it. Nobody searches 'coastal linen throw pillow' by name, but they'll stop scrolling for one shown in a well-lit living room. Meta also gives you retargeting at a fraction of Google's display costs, which matters for anything with a longer consideration window.
- Visual, discovery-driven products: apparel, home goods, furniture
- Real estate and hospitality listings that sell on imagery
- New or unfamiliar brands that need awareness before demand exists
- Retargeting website visitors who didn't convert on the first visit
How budget size changes the answer
Below roughly $2,000/month, splitting budget across two platforms usually means neither gets enough spend to exit the learning phase and produce reliable data. At that level, pick the platform that matches your dominant sales motion and go deep on one channel first. Above $4,000-5,000/month, running both in a deliberate ratio, often 60/40 or 70/30 favoring whichever channel matches your core intent, tends to outperform an all-in bet on either one.
Signals that you're on the wrong platform
- 1.Cost per lead is climbing month over month with no clear seasonal explanation
- 2.Click-through rate is healthy but conversion rate on landing pages is flat
- 3.Sales team reports leads that aren't ready to buy or don't remember requesting info
- 4.Impression volume is capped and can't scale without cost spiking
How costs actually compare by industry
Cost per click on Facebook typically runs $0.50-$2.00 across most categories, versus $2-$10+ for competitive Google Ads keywords in home services, legal, and insurance. That gap makes Facebook look cheaper on paper, but conversion rate tells a different story. A plumbing search ad on Google might convert at 8-12% because the visitor already needs a plumber today, while a Facebook ad for the same service might convert at 1-3% because most viewers weren't in-market at all. Run the math to cost per lead rather than cost per click, and the two channels often land within striking distance of each other, or Google pulls ahead for urgent categories.
A quick industry cheat sheet
- Home services (plumbing, HVAC, roofing): Google Ads primary, Facebook for retargeting and seasonal promos
- Legal and healthcare: Google Ads primary, Facebook mainly for brand awareness and review-driven trust building
- E-commerce and apparel: Facebook/Instagram primary for discovery, Google Shopping and search for branded and comparison terms
- Real estate: Facebook/Instagram for listing awareness, Google for buyer- and seller-intent searches like 'sell my house fast'
- B2B services: Google search for bottom-funnel terms, Facebook/LinkedIn for top-of-funnel retargeting
There's no universal winner between these two platforms, only a better or worse fit for how your specific buyer shops. If you're not sure which side of that line your business falls on, it's worth walking through your sales cycle and current numbers on a strategy call before committing another quarter of budget to the wrong channel.
Frequently asked questions
- Which platform is cheaper, Google Ads or Facebook Ads?
- Cost per click is usually lower on Facebook, but cost per lead often ends up comparable or higher because conversion rates on interruption-based ads tend to trail search ads. The better question is cost per qualified lead, not cost per click, and that varies heavily by industry and offer.
- Can I run both platforms at the same time?
- Yes, and for most businesses with a monthly budget above roughly $3,000-4,000 that's the right move. Google captures people already searching, Facebook builds awareness and retargets people who visited but didn't convert. They work well as a pair rather than a choice.
- Is Facebook Ads still worth it for B2B?
- It can be, mainly for retargeting website visitors and building brand recognition ahead of a longer sales cycle, but it rarely produces cold, high-intent leads the way LinkedIn or Google search does for B2B services. Budget should skew toward search intent channels first.
- How much budget do I need to test which platform works for my business?
- Plan on at least 4-6 weeks and $1,500-3,000 per platform to get past the learning phase and gather enough conversion data to judge performance fairly. Shorter or smaller tests tend to produce noisy, unreliable results.
