How to Use B2B Data with LinkedIn Ads and Google Ads: The Match Rate Reality Nobody Talks About

You've built the perfect prospect list.

Decision makers at target accounts. Verified emails. Mobile numbers. Company data.

Now what?

Most B2B teams upload their lists to LinkedIn Ads, Google Ads, or both, and assume the platform handles the rest. But here's what most agencies won't tell you:

Where you use B2B data matters more than the data itself.

The same professional email list can achieve:

• 40–70% match rate on LinkedIn
• 10–25% match rate on Google

That's a 3–7x difference in targetable audience from identical data.

This isn't about data quality.

It's about platform architecture.

Understanding this difference is the line between:

• wasted ad spend
• and campaigns that actually convert.

---

The Professional Email Problem

Let's start with what B2B data platforms like Inoopa actually provide:

• Professional email addresses
• Mobile numbers
• Company profiles
• Decision-maker roles

All verified and continuously updated across Belgium and the Netherlands.

But platforms identify users differently.

LinkedIn Identifies People as Professionals

Every LinkedIn user has:

• company
• job title
• seniority
• industry

attached to their profile.

When you upload professional emails, LinkedIn maps them directly to these professional identities.

Result:

High match accuracy.

---

Google Identifies People as Consumers

Google identifies users through:

• personal Gmail accounts
• Android devices
• Chrome browser sign-ins

Professional emails only match if someone is actively using Google services with their work email.

Most people in Belgium and the Netherlands are not.

Why?

Because:

60–75% of BeNeLux companies use Microsoft 365, not Google Workspace.

Those professional emails simply don't exist inside Google's identity ecosystem.

The Match Rate Reality

Here's what happens when uploading a 10,000-contact B2B list.

---

LinkedIn Ads

Match Rate

40–70%

Targetable Audience

4,000–7,000 people

Why It Works

Professional emails map directly to LinkedIn profiles.

LinkedIn understands:

• employer
• seniority
• role
• industry

Minimum Audience

300 matched members

---

Google Ads Customer Match

Match Rate

10–25%

Targetable Audience

1,000–2,500 people

Why It Struggles

Professional emails only match if users are logged into Google with work accounts.

Most aren't.

Minimum Audience

1,000 matched users

---

Same data.

Completely different results.

These are not theoretical estimates.

These are real-world match rates observed using Inoopa data.

---

LinkedIn Ads: Your Primary B2B Targeting Channel

LinkedIn is structurally aligned with the type of data Inoopa provides.

---

1. Contact Targeting with Matched Audiences

Upload:

• decision-maker emails
• names
• company names

LinkedIn matches them against professional profiles.

Benefits

• 40–70% match rate
• precise targeting
• seniority filters
• role-based segmentation
• lower minimum audience threshold

Example

A warehouse automation company uploads:

• 2,000 operations directors
• logistics companies only

LinkedIn matches:

1,200 decision makers directly.

---

2. Company Targeting

Upload:

• company names
• websites
• LinkedIn company URLs

Then target:

every employee inside those companies.

This creates one of the strongest ABM strategies available today.

Example

A cybersecurity company:

• uploads 400 manufacturing companies
• filters by IT + Director+

Result:

highly precise decision-maker targeting impossible on Google.

---

3. Decision-Maker Clusters Map Perfectly to LinkedIn

Inoopa segments contacts into:

• IT/R&D
• Finance
• Sales/Marketing
• CEO/Board
• HR
• Operations

These map directly to LinkedIn job functions.

Result:

tailored campaigns by role and buying motivation.

A CFO should not see the same message as a CTO.

---

4. Look-Alike Expansion That Actually Makes Sense

LinkedIn builds audience expansion using:

• professional behavior
• company characteristics
• seniority
• industry

Not random consumer behavior.

When seeded with high-quality Inoopa data:

LinkedIn finds genuinely similar professionals.

---

The Trade-Off: Cost

LinkedIn CPCs are higher.

Typical:

• LinkedIn CPC: €8–15
• Google Search CPC: €2–4

But you're paying for precision.

If you're targeting:

Operations Directors at logistics companies

then the higher CPC is justified.

---

Google Ads: The Supporting Channel

Google is not bad for B2B.

It's simply:

better as a supporting layer.

---

1. Mobile Numbers Matter More Than Emails

Mobile numbers generally match better on Google.

Why?

Because they connect to:

• Android accounts
• personal Google identities
• Google Pay accounts

Strategic Insight

If enriching Inoopa data:

prioritize mobile numbers for Google campaigns.

This can:

• double match rates
• improve audience size significantly

---

2. Performance Max Audience Signals

Even low match rates still create valuable audience signals.

Example

10,000 contacts uploaded:

• 15% directly matched
• Performance Max uses them as seed signals

Google then expands toward:

• similar users
• similar behaviors
• similar search patterns

This is one of the most underrated uses of B2B data today.

---

3. Suppression Lists

Use existing customers as exclusion audiences.

Exclude:

• existing customers
• competitors
• irrelevant sectors
• bad-fit company sizes

This alone can save:

tens of thousands in wasted ad spend annually.

---

4. Segment Campaigns by Firmographics

Use:

• NACE codes
• employee ranges
• regions
• sectors

to personalize:

• landing pages
• messaging
• creatives

Example

An HR software company creates:

• manufacturing-specific pages
• logistics-specific pages
• retail-specific pages

Result:

significantly higher conversion rates.

---

5. Retargeting Layer

Best practice:

Step 1

Use LinkedIn for precise targeting.

Step 2

Drive visitors to landing pages.

Step 3

Retarget visitors via Google Search and Display.

This combination:

• lowers blended CAC
• captures intent cheaply
• increases total conversion rate

---

The Combined Strategy That Actually Works

---

Step 1: Define Your ICP with Semantic Search

Instead of:

outdated industry codes

use:

semantic business descriptions.

Example

Manufacturing companies in Belgium doing industrial automation

Inoopa understands actual activity, not just classifications.

---

Step 2: Export Decision-Maker Data

Export:

• professional emails
• mobile numbers
• company LinkedIn URLs
• names and titles

---

Step 3: Upload to LinkedIn Matched Audiences

Create:

• contact audience
• company audience

Expected match rate:

40–70%

---

Step 4: Layer LinkedIn Filters

Add:

• seniority
• job functions
• exclusions

---

Step 5: Build Segment-Specific Landing Pages

Different decision makers need different messaging.

CFO

• ROI
• savings
• efficiency

CTO

• integrations
• architecture
• scalability

---

Step 6: Upload Data to Google Customer Match

Use:

• mobile numbers first
• emails second

Use primarily as:

audience signals.

---

Step 7: Retarget Through Google

LinkedIn generates awareness.

Google captures buying intent later.

This combination consistently lowers acquisition costs.

---

What NOT to Do

Don't Expect 100% Match Rates

Realistic benchmarks:

• LinkedIn: 40–70%
• Google: 10–25%

Plan audience sizes accordingly.

---

Don't Upload and Forget

B2B data decays quickly.

Best practice:

refresh lists quarterly.

---

Don't Ignore GDPR

Always validate compliance internally.

Especially for:

• cold audiences
• large uploads
• cross-border targeting

---

Don't Use Generic Creative

Segment by:

• role
• industry
• company size

Generic ads get ignored.

Specific messaging converts.

---

Don't Skip Suppression Lists

Fastest ROI improvement possible.

---

Real-World Example

• semantic search
• precise operations directors targeting
• LinkedIn matched audiences
• Google retargeting
• suppression lists

Results

• €80K spend
• 89 demos booked
• €899 cost per demo

---

The Mobile Number Advantage

Most agencies underestimate this.

Professional Emails

Better on LinkedIn.

Mobile Numbers

Better on Google.

If you're serious about Google Ads:

mobile enrichment is one of the highest-value additions possible.

---

Conclusion: Platform Architecture Determines Strategy

The takeaway isn't:

LinkedIn good, Google bad.

The takeaway is:

platform architecture determines where B2B data performs best.

LinkedIn

Professional identity platform.

Google

Consumer identity platform.

Winning strategy:

• LinkedIn for precision targeting
• Google for retargeting and intent capture
• Semantic search to ensure targeting quality

Because:

data quality matters, but platform strategy matters even more.

---

FAQ: LinkedIn Ads vs Google Ads for B2B

Why do professional emails match better on LinkedIn?

Because LinkedIn profiles are built around professional identities:

• employer
• title
• industry

Google primarily identifies personal consumer accounts.

---

What's a realistic match rate?

• LinkedIn: 40–70%
• Google: 10–25%

---

Should I use both platforms?

Yes.

Use:

• LinkedIn for targeting
• Google for retargeting and intent capture

---

Mobile numbers or professional emails?

• LinkedIn → professional emails
• Google → mobile numbers

---

How often should lists be refreshed?

Quarterly.

B2B data decays rapidly due to:

• job changes
• company changes
• inactive emails

---

Does GDPR allow B2B ad targeting?

Generally yes for B2B data in BeNeLux, but legal validation is recommended.
