LinkedIn Ads vs Google Ads for B2B
When to use each channel, based on benchmark data from 87 B2B clients
The Short Answer
Google Ads = Demand capture. People searching for solutions you offer.
LinkedIn Ads = Demand creation. Reaching your ICP before they search.
Most B2B companies need both. If you can only pick one, start with Google if you have search volume for your category. Start with LinkedIn if you're creating a new category or have a niche ICP.
LinkedIn first, Google second.
For B2B SaaS selling to mid-market and enterprise, we start every client on LinkedIn. The targeting precision means you're reaching decision-makers, not researchers. Google captures demand—but LinkedIn creates it. Start with LinkedIn to build pipeline, add Google to capture high-intent searches once you have budget to expand.

When should you run LinkedIn Ads vs Google Ads?
Use Google Ads When...
- ✓ Your category has established search volume (1,000+ monthly searches for core keywords)
- ✓ You need leads fast—Google delivers results in 2-4 weeks vs 4-8 for LinkedIn
- ✓ Your ACV is under $25,000 and you need volume over precision
- ✓ You're selling to SMB or mid-market where broad targeting works
- ✓ Prospects self-educate and compare solutions before talking to sales
Use LinkedIn Ads When...
- ✓ You're targeting specific job titles, companies, or industries (ABM)
- ✓ Your category is new or has low search volume
- ✓ You're selling to enterprise (ACV $50K+) where precision matters more than volume
- ✓ You need to build awareness and educate the market first
- ✓ Your buying committee has 5+ people and you need multi-threaded engagement

The 42 Channel Mix Framework
Instead of choosing one channel, allocate budget based on your stage and motion:
Early Stage / Need Pipeline Now
70% Google / 30% LinkedIn
Prioritize Google Search for high-intent demand capture. Use LinkedIn for retargeting and light ABM on top 50 accounts.
Growth Stage / Scaling Pipeline
50% Google / 50% LinkedIn
Balance demand capture and creation. Google for bottom-funnel, LinkedIn for awareness and mid-funnel content engagement.
Enterprise / ABM-Heavy
30% Google / 70% LinkedIn
LinkedIn dominates for precision targeting of named accounts. Google captures the hand-raisers who research independently.
Category Creation / Low Search Volume
20% Google / 80% LinkedIn
When people aren't searching for what you sell, LinkedIn is the primary channel. Use Google for brand and competitor conquesting only.
Budget Allocation Reality Check
Most B2B teams should allocate 60-70% to LinkedIn when starting, shifting to 50/50 as Google campaigns mature. Here's why: LinkedIn gives you the targeting control to validate messaging and ICP fit before you scale. Google search is brutal if your positioning isn't dialed in—you'll burn budget on clicks that don't convert.
Our recommendation: Prove your funnel works on LinkedIn first (3-6 months), then add Google to capture the demand you've created.
What common mistakes do B2B marketers make with LinkedIn and Google Ads?
Running Google Ads without CRM-connected conversion tracking
If you're only tracking form fills, you're optimizing for MQLs—not revenue. Connect Google Ads to your CRM (HubSpot, Salesforce) and import offline conversions. Otherwise you're flying blind on which keywords actually generate pipeline.
Using LinkedIn Lead Gen Forms without validation
Lead Gen Forms have 2-3x higher conversion rates, but also 40% more junk. LinkedIn auto-fills from outdated profile data. Always validate emails on form submission and route through your qualification criteria before it hits CRM.
Not excluding competitors and job seekers
On both platforms, you're paying for clicks from people who will never buy. On LinkedIn: exclude competitor company names, "seeking opportunities," and students. On Google: negative keywords for careers, jobs, reviews, and competitor brand + "vs" queries.
Frequently Asked Questions
Should I use LinkedIn Ads or Google Ads for B2B?
Use Google Ads for demand capture when prospects are actively searching for solutions. Use LinkedIn Ads for demand creation to reach your ICP before they're in-market. Most B2B companies need both: Google for bottom-funnel conversions (demos, trials) and LinkedIn for awareness, ABM, and mid-funnel nurture. If budget is limited, start with Google Ads if you have search volume for your category.
Which is cheaper: LinkedIn Ads or Google Ads?
Google Ads typically has 40-60% lower CPL than LinkedIn Ads. Google B2B CPL ranges from $50-$400 while LinkedIn averages $200-$600. However, LinkedIn leads often have higher conversion rates to opportunity (15-25% vs 8-15% for Google) due to superior targeting precision. Calculate cost-per-opportunity, not just CPL.
What is a good budget split between LinkedIn and Google Ads?
A typical B2B budget split is 60% Google Ads / 40% LinkedIn Ads for demand capture-heavy motions, or 40% Google / 60% LinkedIn for ABM and enterprise sales. Start with 70/30 toward Google if you're early-stage and need immediate pipeline, then shift toward LinkedIn as you scale brand awareness.
When should I use LinkedIn Ads instead of Google Ads?
Use LinkedIn Ads when: (1) Your category has low search volume (<1,000 monthly searches), (2) You're targeting specific job titles or companies (ABM), (3) You're selling to enterprise buyers with long sales cycles, (4) You need to build awareness in a new market, (5) Your product requires education before purchase intent forms.
Can I run both LinkedIn and Google Ads with a small budget?
Below $8,000/month total, pick one channel and do it well. Splitting a small budget dilutes results on both platforms. Google needs ~$3,000/month minimum per campaign to gather enough data. LinkedIn needs ~$5,000/month. Once you're at $15,000+/month, you have enough to run both effectively.
