A common question in the r/googleads community goes something like this: "Our industry is expensive on Google — should I be running ads on Facebook or other social platforms instead?" It's a reasonable instinct, and the answer isn't as simple as "Google wins every time." After managing over $350M in paid media spend across industries ranging from local services to enterprise SaaS, I can tell you the real decision comes down to buyer intent, funnel stage, audience behavior, and your specific economics — not platform loyalty.
Why "Expensive" on Google Isn't the Same as "Bad Value"
When practitioners see CPCs of $15, $40, or even $80+, the gut reaction is sticker shock. But cost-per-click is one of the least useful metrics for making channel allocation decisions. What matters is cost-per-acquisition (CPA) relative to your customer lifetime value (LTV).
In high-CPC verticals — think legal, financial services, insurance, home services, and medical — Google's search network is expensive precisely because it works. Advertisers don't keep bidding $60 per click out of stubbornness. They do it because the conversion rates and deal sizes justify it.
Key Insight: A $50 CPC with a 10% conversion rate and a $2,000 LTV is dramatically better economics than a $2 CPC with a 0.3% conversion rate and the same LTV. Never evaluate channel cost in isolation from conversion rate and deal value.
Here's a simple framework I use when evaluating channel economics:
- Google Search: High intent, lower volume, higher CPC, typically higher CVR
- Facebook/Meta: Lower CPC, much higher volume potential, lower intent, requires stronger creative and funnel
- Microsoft Ads: Lower CPC than Google (often 20–40% cheaper), older demographic skew, smaller volume
- YouTube: Mid-funnel awareness & consideration, CPM-based, excellent for brand building at scale
- LinkedIn: B2B powerhouse, expensive (CPCs of $8–$15+ common), but unmatched for job title & company targeting
Google Search: When It's the Right Default
As practitioners often discuss, for industries where purchase decisions start with a search query, Google Search should almost always be your first dollar spent. The reason is simple: you're capturing demand that already exists. Someone searching "emergency plumber near me" or "personal injury lawyer Chicago" is ready to act. They have a problem, they want a solution, and they're actively looking.
Industries Where Google Search Dominates
- Legal services (personal injury, family law, criminal defense)
- Home services (HVAC, plumbing, roofing, electrical)
- Medical & dental practices
- Financial services (loans, insurance, tax preparation)
- Local brick-and-mortar businesses
- B2B software with clear problem-aware buyers
Best Practice: Before abandoning Google Search due to high CPCs, audit your Quality Scores, match types, and negative keyword lists. In my experience, 60–70% of "Google is too expensive" campaigns are suffering from structural problems — broad match abuse, missing negatives, or poor landing page relevance — not a platform-level issue. Fix the fundamentals before switching channels.

When Facebook & Social Media Ads Make Sense
Facebook (Meta) and other social platforms aren't inferior to Google — they're different tools for different jobs. The mistake is treating them as direct replacements rather than complements.
Social Media Excels When:
- You need to create demand, not just capture it. If your product or service is new, niche, or not something people actively search for, social is often your only scalable option.
- You have a visual or emotional product. Fashion, home décor, fitness, food & beverage, consumer apps — these categories thrive on Meta's visual formats.
- Your audience is hyper-defined by demographics or interests. Meta's targeting for age, life events, income brackets, and behavioral signals is genuinely powerful for consumer products.
- You're running retargeting campaigns. Facebook retargeting for website visitors is often extremely cost-effective, even in expensive industries.
- You have a long sales cycle and need multiple touchpoints. B2B companies often use LinkedIn or Facebook to nurture leads who found them through Google but weren't ready to convert.
Key Insight: Some of the best-performing paid media strategies I've managed combine Google Search for bottom-of-funnel capture with Meta or YouTube for top-of-funnel awareness. The channels compound each other — users who see your brand on social convert at higher rates when they later search on Google. Attribution models often miss this, so branded search volume is a useful proxy for social awareness effectiveness.
The Facebook Lead Quality Problem in Expensive Industries
Here's the hard truth that doesn't get talked about enough: in high-ticket, high-intent industries, Facebook leads are frequently lower quality than Google leads. Not always, but often.
When someone fills out a Facebook lead form while scrolling through their feed, they're in a passive mindset. When someone searches "DUI attorney near me" and clicks your ad, they're in crisis mode. The intent gap is enormous, and it shows up in your close rates.
I've seen accounts in legal and financial services where Google CPAs were 2–3x higher than Facebook CPAs on paper, but close rates on Google leads were 4–5x higher. Net cost per signed client? Google won decisively.
Common Mistake: Comparing CPA across channels without accounting for lead quality or close rates. Always track downstream metrics — qualified leads, sales conversations, closed deals — not just raw form fills. A $50 Facebook lead that closes at 2% is worse economics than a $300 Google lead that closes at 15%.
The Case for Microsoft Ads (Bing) — Often Overlooked
Before jumping to Facebook in expensive Google verticals, many advertisers skip right past Microsoft Ads, which is a significant missed opportunity. Microsoft Ads (formerly Bing Ads) typically delivers:
- CPCs 20–40% lower than equivalent Google campaigns
- Older, higher-income demographic skew (valuable for financial services, medical, legal)
- Lower competition in most verticals
- Straightforward campaign import directly from Google Ads
In many campaigns I've managed, Microsoft Ads delivers 10–20% incremental volume at meaningfully better CPAs than Google. It's rarely a primary channel, but it's almost always worth running as a complement.
Best Practice: Import your best-performing Google Search campaigns into Microsoft Ads. Adjust bids down 20–30% initially, monitor for 30 days, then optimize independently. Budget allocation of 10–20% of your Google Search budget is typically a reasonable starting point. The setup time is minimal relative to the incremental return.
Building a Multi-Channel Strategy: How to Think About Allocation
Rather than asking "Google or Facebook?" the more productive question is "What role does each channel play in my funnel, and how much should I invest in each stage?"
A Framework for Funnel-Based Channel Allocation
- Start with Google Search (Bottom Funnel) — Capture existing demand first. This is typically your highest-intent, most efficient spend. Max out your budget here before diversifying, as long as CPAs are within target.
- Add Microsoft Ads — Import your Google campaigns, run in parallel. Low effort, incremental volume.
- Layer in Retargeting (Google Display or Meta) — Target your website visitors and unconverted leads. Often the highest-ROI display spend available.
- Test YouTube or Meta for Mid-Funnel — Once bottom-funnel is maxed out and you need more volume, move up the funnel. Focus on educational content, testimonials, case studies.
- Scale What Works, Kill What Doesn't — Run 60–90 day channel tests with clear KPIs before major budget commitments. Let data decide, not instinct.

Industry-Specific Recommendations
As practitioners often discuss when evaluating channel mix, the "right answer" varies significantly by vertical. Here's how I think about it across common high-CPC industries:
Legal Services
Google Search and Local Services Ads (LSAs) should be your foundation — full stop. LSAs in particular often deliver the best cost-per-lead in legal at $50–$150 for verified leads. Facebook can work for brand awareness and retargeting, but lead quality issues are common. LinkedIn is largely irrelevant unless you're doing B2B legal work.
Home Services
Google Search & Local Services Ads dominate. Nextdoor can be surprisingly effective for neighborhood-level targeting. Facebook works for seasonal promotions and community building, but Google captures the emergency/urgent intent that drives home services revenue.
Financial Services & Insurance
Google Search for high-intent keywords, Microsoft Ads for incremental volume (older demographic skews well here), YouTube for product education, and Facebook for retargeting and lookalike audience prospecting. LinkedIn is worth testing for B2B financial services.
B2B SaaS & Technology
Google Search for problem-aware searches, LinkedIn for title/company targeting and account-based marketing (ABM), YouTube for product demos and thought leadership. Facebook B2B results are mixed — test it, but don't lead with it.
E-commerce & Consumer Products
Google Shopping campaigns are often the backbone. Meta (Facebook & Instagram) is critical for visual discovery and retargeting. YouTube is powerful for product launches. Pinterest works surprisingly well in categories like home, fashion, and food.
What to Do Next: A Concrete Action Plan
If you're currently running Google Ads in an expensive industry and wondering whether to diversify to social media, here's exactly what I'd do:
-
Audit your Google Ads account first. Before spending a dollar elsewhere, make sure your Google campaigns are structurally sound. Check Quality Scores (aim for 7+), review match types (minimize broad match without smart bidding support), audit your negative keyword lists, and benchmark your landing page conversion rates against industry averages. Fix your foundation before building new channels.
-
Set up conversion tracking that goes beyond form fills. Implement offline conversion imports or at minimum track calls, qualified leads, and — if possible — closed revenue. You cannot make intelligent channel allocation decisions without quality downstream data.
-
Add Microsoft Ads as your first expansion move. Import your top Google campaigns, set bids 20–30% lower, and run for 60 days. This is the lowest-effort, highest-probability incremental win available to most advertisers.
-
Test retargeting on Meta before prospecting. If you're going to test Facebook, start with retargeting your Google Ads website visitors. This captures the warm audience you've already paid to attract and typically delivers much stronger ROI than cold audience prospecting.
-
Run channel tests with clear success criteria. Before scaling any new channel, define your target CPA, set a minimum test budget (typically 2–3x your target CPA per week to generate statistical significance), and commit to a 60–90 day evaluation window. Don't make channel decisions based on 2 weeks of data.
Best Practice: The advertisers who win in expensive Google verticals are rarely the ones who abandon the platform — they're the ones who master it while intelligently layering complementary channels on top. Intent-driven search will almost always be your most efficient acquisition channel when properly structured. Build from that foundation outward.
The bottom line: "Google is expensive" is often a symptom of campaign structure problems, not a reason to migrate budget to social media. Diagnose before you diversify, capture demand before you create it, and always measure channel performance on the metrics that actually connect to revenue — not just the ones that are easy to track.
