B2B paid advertising works when each platform does the job it’s good at. Google Search captures buyers who are already looking for a solution. LinkedIn reaches specific job roles and companies, whether or not they’re looking yet. Meta retargets people who already know you and extends your reach at a lower cost. The mistake is asking one platform to do all three, or judging all three by cost per lead.
This guide covers how to choose between them, how to split a budget, what published benchmarks actually say, and how to measure paid ads by the pipeline they create.
Key takeaways
- Google Search for capture, LinkedIn for precise targeting, Meta for retargeting and reach.
- Compare platforms on cost per qualified lead and cost per opportunity, not cost per lead.
- Send CRM outcomes (qualified, opportunity, won) back to each platform so bidding optimizes for real buyers.
- Most of your market isn't buying this quarter. Some of your budget should reach them anyway.
- Give each platform a 90-day test with a clear budget and success metric before you judge it.
The platforms at a glance
- 1.3 billion+ LinkedIn members LinkedIn, 2026
- 3.48 billion people using at least one Meta app daily (June 2025 average) Meta Q2 2025 results
- $10 minimum daily budget to run LinkedIn ads, for any ad format LinkedIn Marketing Solutions
- $66.69 average cost per lead for search ads across industries LocaliQ and WordStream, 2026
LinkedIn’s reach is spread across regions, which matters if you sell into more than one market:
Each platform does a different job for a B2B advertiser:
| Google Search | Meta (Facebook, Instagram) | ||
|---|---|---|---|
| Main job | Capture active demand | Reach named roles and accounts | Retarget and build reach cheaply |
| Buyer state | Searching for a solution now | Working; may not be looking | Off-duty scrolling |
| Targeting strength | Search intent (keywords) | Job title, function, seniority, company, industry, company size | Your own lists, site visitors, engagement, broad interests |
| Typical B2B formats | Search ads, Performance Max (with care) | Single image, Document ads, Thought Leader Ads, Lead Gen Forms | Retargeting video and image, lead forms, carousel |
| Main cost driver | Competition for your keywords | Audience size and seniority; narrow, senior audiences cost more | Audience and placement; broad audiences cost less |
| Common failure | Broad match spending on job seekers and students | Lead forms that collect contacts sales can’t use | Cheap leads that never qualify |
| Best first test | Bottom-of-funnel keywords: your category plus “software”, “agency”, “pricing”, “alternatives” | One tightly defined audience, one offer | Retargeting site visitors and video viewers |
Google Ads for B2B: capture demand that already exists
Search ads are the closest thing to buying intent. Someone typing “SOC 2 compliance consultant” is further along than anyone scrolling a feed. That’s why Google Search is usually the first paid channel for B2B. It’s also why it gets expensive.
Here’s what published benchmarks show for search advertising in 2026. They come from thousands of LocaliQ and WordStream customer campaigns across Google Ads and Microsoft Ads, so treat them as a rough reference, not a target:
| Category (2026) | Avg. cost per click | Avg. click-through rate | Avg. conversion rate | Avg. cost per lead |
|---|---|---|---|---|
| All industries | $5.42 | 6.64% | 8.18% | $66.69 |
| Business Services | $5.87 | 6.10% | 4.85% | $93.69 |
| Industrial & Commercial | $5.87 | 6.57% | 8.20% | $75.19 |
| Finance & Insurance | $3.39 | 9.83% | 2.64% | $74.44 |
Source: LocaliQ and WordStream Search Advertising Benchmarks, 2026. A “lead” here is any contact: a call, form, chat or email. It isn’t a qualified B2B lead.
What makes Google Search work for B2B pay-per-click advertising:
- Start narrow. Exact and phrase match on decision-stage terms first. Expand once you know which queries produce qualified leads.
- Build a negative keyword list on day one. Exclude “jobs”, “salary”, “course”, “free”, “template”, “definition” and anything consumer-flavored.
- Read the search terms report weekly. It shows what people actually typed. It’s the fastest way to stop waste.
- Send traffic to a page built for the ad. One offer, proof and a short form. Not your homepage.
- Be careful with fully automated campaign types. They optimize for whatever conversion you give them. If that’s “form fill,” they’ll find cheap form fills.
LinkedIn ads for B2B: reach the right people before they search
LinkedIn is the one platform where you can target by job function, seniority, company, industry and company size with real precision. That makes it the natural home for account-based marketing and for reaching buying-group members who will never type your category into Google.
The minimum to run is low ($10 a day for any format, and $100 lifetime for a new campaign), but LinkedIn suggests $25 a day for new advertisers (LinkedIn). In practice, you need enough budget per audience for the campaign to learn, so run fewer audiences with more budget each.
What works:
- Tight audiences. One role group in one segment, for example finance leaders at fintech companies with 50–500 employees, beats “decision makers in tech.”
- Useful offers. A benchmark, a checklist, a short assessment. Not “book a demo” to people who’ve never heard of you.
- People, not logos. Thought Leader Ads let you promote posts from your founder or experts. They often read as more human than brand ads.
- Lead Gen Forms with care. They’re convenient and pre-filled, which is exactly why quality can drop. Add one qualifying question, and follow up within a day.
LinkedIn’s B2B Institute popularized the “95-5 rule”: most potential buyers aren’t in the market at any given moment (LinkedIn B2B Institute). If all your paid budget chases the few who are ready now, you’ll pay a premium for them, and nobody will know you when the rest are ready. A share of LinkedIn spend should build familiarity with the right people, measured by reach and engagement in your target accounts, not leads.
Meta ads for B2B: retargeting and cheap reach
Meta isn’t where B2B buyers go to look for vendors, but they’re there every day. That makes it useful for two jobs:
- Remarketing. Show proof, case stories and offers to people who visited your pricing or service pages, watched your videos or opened your emails.
- Reach from your own data. Upload customer or pipeline lists (with the right consent) and build lookalike audiences, or reach broad audiences with video and let engagement tell you who cares.
Be strict about lead quality. Meta’s lead forms can produce lots of low-intent contacts. Use a higher-intent form type, add a qualifying question, and judge Meta by qualified leads and assisted pipeline, not raw volume.
Worked example: splitting a $5,500 monthly budget
Here’s how we compare platforms. The Google cost per lead uses the 2026 Business Services benchmark above. Every other input is illustrative; replace them with your own numbers after the first month.
Google Search: $3,000
- Leads at a $93.69 cost per lead: 3,000 ÷ 93.69 = 32 leads
- Qualified at 30%: 32 × 30% = 9.6 qualified leads
- Cost per qualified lead: 3,000 ÷ 9.6 = $312.50
LinkedIn: $2,000
- Leads at an assumed $150 cost per lead: 2,000 ÷ 150 = 13.3 leads
- Qualified at 45% (tighter targeting): 13.3 × 45% = 6.0 qualified leads
- Cost per qualified lead: 2,000 ÷ 6 = $333.33
Meta retargeting: $500
- Leads at an assumed $50 cost per lead: 500 ÷ 50 = 10 leads
- Qualified at 20%: 10 × 20% = 2 qualified leads
- Cost per qualified lead: 500 ÷ 2 = $250
Total: $5,500 for 17.6 qualified leads, or 5,500 ÷ 17.6 = $312.50 per qualified lead.
Look at what happened. By cost per lead, LinkedIn looks three times worse than Meta. By cost per qualified lead, the three are within $85 of each other. Go one step further to opportunities and the order can flip again. That’s why the only fair comparison is one that follows the lead into your CRM. Then check the result against your customer acquisition cost ceiling.
Measure paid ads by pipeline, not clicks
Every platform optimizes toward the conversion you report. If you only report form fills, you get form fills. Feed back what happens after the form:
- Google Ads: use enhanced conversions for leads to send qualified and closed outcomes from your CRM back to Google.
- LinkedIn: set up the Conversions API to send offline and CRM events alongside the Insight Tag.
- Meta: use the Conversions API with the Meta Pixel and send lead-quality events from your CRM.
Then report in your CRM, not in each platform’s dashboard. Platforms each claim credit for the same deal. Agree on an attribution model that suits your sales cycle, and add a self-reported “How did you hear about us?” field. For long B2B cycles, look at first-touch and multi-touch views side by side.
Creative: the variable you control most
Targeting is increasingly automated. Creative is where you still make the difference.
- One message per ad. The problem, the outcome and the proof. Not your full service list.
- Show the product or the work. Real dashboards (with client data blurred), real deliverables, real people from your team.
- Test one variable at a time. Hook, format or offer. Keep the rest constant so you know what moved the number.
- Refresh before fatigue. Watch frequency and click-through rate. When click-through drops as frequency climbs, rotate.
- Label examples. If an ad shows a sample brand or mockup, say so.
Our paid ads creative brief template covers formats and specs for each platform.
Myth vs fact
- MythMeta doesn't work for B2B.
- FactMeta is weak at finding new B2B buyers by job title, but strong for retargeting and cheap reach to people who already know you. Judge it on assisted pipeline, not first-touch leads.
- MythLinkedIn is too expensive for small budgets.
- FactThe minimum is $10 a day. It's expensive per click, but if tight targeting raises the share of leads that qualify, cost per qualified lead can be competitive. Run one focused audience instead of five thin ones.
- MythThe platform with the lowest cost per lead is the winner.
- FactCost per lead ignores quality. Compare cost per qualified lead and cost per opportunity, using CRM data.
- MythTurn on automated campaigns and let the algorithm find buyers.
- FactAutomation optimizes toward the signal you give it. Without CRM outcomes fed back, it optimizes for the cheapest form fill.
Before I'll talk about scaling a paid budget, I want to see lead outcomes flowing back from the CRM. Without that, every platform looks good on its own dashboard, and the algorithm learns to find cheap form fills. Start with one platform, one offer and a budget you can hold long enough for a fair test. A focused test beats a scattered one.

Frequently asked questions
What is B2B paid advertising?
B2B paid advertising is paid media aimed at business buyers: search ads, LinkedIn ads, Meta ads, display and others. Its job is to put your offer in front of the right companies and roles, capture active demand, and keep you familiar to buyers who aren't ready yet. It should be measured by qualified leads and pipeline.
Which is better for B2B, LinkedIn or Google Ads?
They do different jobs. Google Search captures people already searching for your solution. LinkedIn reaches specific roles and companies whether or not they're searching. Most B2B companies start with Google Search for demand capture and add a focused LinkedIn audience, then compare both on cost per qualified lead.
Do Facebook and Instagram ads work for B2B?
Yes, mainly for retargeting and low-cost reach. Meta is less precise for finding new buyers by job title, but it's effective at reminding site visitors and engaged contacts about your offer. Judge it on qualified leads and assisted pipeline rather than raw lead volume.
How much should a B2B company spend on paid ads?
Work back from your pipeline target and a cost-per-qualified-lead ceiling. Make sure each platform has enough budget to learn: LinkedIn's minimum is $10 a day, but it suggests $25 a day for new advertisers. A focused test across one or two platforms for 90 days is better than thin spend everywhere.
What is a good cost per lead for B2B Google Ads?
LocaliQ and WordStream's 2026 benchmarks put the average search cost per lead at $66.69 across industries and $93.69 for Business Services. Treat these as context, not targets. The number that matters is your cost per qualified lead and per opportunity, measured in your CRM.
How do I track B2B ad leads through to revenue?
Record source, campaign and click IDs on every lead in your CRM. Then send qualified, opportunity and closed-won events back to each platform with Google's enhanced conversions for leads, LinkedIn's Conversions API and Meta's Conversions API. Report pipeline from the CRM, not from each ad dashboard.
The short version
B2B paid advertising isn’t a choice between LinkedIn, Google and Meta. It’s giving each the right job, a fair budget and a measurement setup that follows leads into the CRM. Start with demand capture, add precise targeting, retarget everyone who shows interest, and move budget by cost per qualified lead.
