LinkedIn Ads vs Google Ads for B2B
LinkedIn Ads and Google Ads run on opposite logic. LinkedIn targets who someone is. Google targets what someone is searching for. Both work for B2B, but they pull pipeline in very different ways. Here is the data on cost, intent quality, and which channel fits which use case.
LinkedIn Ads
Audience-targeted B2B advertising
Google Ads
Intent-driven search advertising
Side-by-side comparison
| Dimension | LinkedIn Ads | Google Ads |
|---|---|---|
| Targeting basis | Job title, company, industry, seniority | Search keyword, intent signal, audience |
| Average CPM (B2B) | $30 to $80 | $5 to $20 |
| Average CPC (B2B) | $5 to $12 | $2 to $8 |
| Average cost per qualified lead | $80 to $250 | $60 to $300 |
| Lead quality (B2B fit) | High (real titles, real companies) | Variable (depends on keyword intent) |
| Intent strength | Low (passive scrollers) | High (active searchers) |
| Time to first qualified lead | 1 to 7 days | Same day for high-intent terms |
| Best ad formats | Sponsored Content, Thought Leader Ads, Conversation Ads | Search, Performance Max, YouTube |
| Minimum useful budget per month | $3,000 to $5,000 | $1,000 to $3,000 |
Bolded cells indicate the option that wins on that dimension based on B2B founder use cases.
When to use LinkedIn Ads
Your buyer is hard to reach via search
If your ICP is a CFO at a 200-person logistics company, that person is not actively searching for your category. LinkedIn Ads can find them based on title and company. Google Ads cannot.
You sell into a category buyers do not search for
New product categories, complex services, or solutions where the buyer does not yet know your name benefit from interruption-style awareness. LinkedIn delivers this.
You have a strong content team
LinkedIn Ads work best when paired with organic content. Thought Leader Ads (boosting a real person's post) outperform standard sponsored content by 2x and require existing organic posts to amplify.
You want account-based targeting
LinkedIn Matched Audiences allow uploading a list of target accounts and serving ads only to people at those companies. No other platform matches this precision.
When to use Google Ads
Your buyer searches for a defined keyword
If prospects type 'invoice automation software' or 'best CRM for agencies', Google captures that intent the moment it happens. LinkedIn cannot match this.
You need fast pipeline within a week
Google Ads can produce a qualified demo request in 24 to 48 hours. LinkedIn typically takes 1 to 2 weeks to optimize a campaign to that level.
Your budget is under $3,000 per month
LinkedIn's higher CPMs make budgets under $3,000 per month statistically noisy. Google Ads work at much lower budgets because clicks are cheaper.
You sell a known category to known searchers
Established categories (CRM, project management, accounting software) have clear search demand. Google captures buyers in the moment they are researching.
The verdict
Run both, with different jobs. Google Ads captures bottom-of-funnel intent (people actively searching). LinkedIn Ads creates demand among buyers who have not yet searched. For B2B teams under $5,000 per month, start with Google and add LinkedIn once the baseline pipeline is consistent. For teams over $20,000 per month, the right split is roughly 40 percent LinkedIn (demand creation) and 60 percent Google (intent capture).
Frequently asked questions
Are LinkedIn Ads or Google Ads better for B2B?
Different jobs. Google Ads is better for capturing existing intent (people searching for your category). LinkedIn Ads is better for creating awareness among buyers who have not yet searched. Most successful B2B advertisers run both, with Google taking the larger share of budget early and LinkedIn growing as account-based targeting becomes valuable.
Why are LinkedIn Ads so expensive?
LinkedIn's CPM is 4 to 10 times higher than Google's because the audience is precisely targeted and the inventory is limited. A CFO at a $50M company is harder to reach than a generic search. The trade-off is that LinkedIn audiences convert to qualified leads more reliably, so cost per qualified lead is often comparable to Google despite the higher CPM.
What is the minimum budget to run LinkedIn Ads effectively?
Realistically $3,000 to $5,000 per month. Below that, the audience is small enough that you cannot get statistically significant results. The platform requires 100 to 200 leads per month to optimize properly, and with $80 to $250 cost per lead, that math sets the budget floor.
Can I run the same ad copy on LinkedIn and Google?
Almost never. Google Ads copy answers a search query directly ('Get a CRM in 5 minutes'). LinkedIn Ads copy creates a pattern interrupt for someone scrolling ('What 200 SaaS founders learned about retention'). The two platforms reward opposite copywriting approaches.
Which platform works better for SaaS demos?
Google Ads usually wins for demo bookings on established categories where buyers actively search. LinkedIn Ads wins for demo bookings on new categories or for selling to roles that do not search proactively (executives, CFOs, ops leaders). The exact answer depends on your category maturity and ICP.
