LinkedIn Ads vs Google Ads for B2B: Which Should a Startup Fund First?

Google Ads captures existing demand: people actively searching for a solution. LinkedIn Ads creates demand among precisely defined professionals who may not be searching yet. If your buyers already search for your category, competitors or problem, start with Google Ads. If they don't, or if you sell to a small, specific set of roles and companies, LinkedIn is usually the better first test.

Key takeaways

• Google = intent (what people search). LinkedIn = identity (who people are at work).
• Check search demand before choosing. Low search volume means Google Ads has little to capture.
• LinkedIn clicks typically cost more than Google search clicks, but its targeting can justify the cost for high-value deals.
• LinkedIn works best with offers for people who aren't ready to buy yet. Google works best with offers for people who are.
• Many B2B companies end up running both: Google to capture, LinkedIn to create and retarget.

How the two channels differ

The deciding question: is there search demand?

Before choosing, look up how many people search for:

• Your category ("[category] software")
• Your competitors' names, plus "alternative" and "pricing"
• The specific problem you solve

Google's Keyword Planner is free with a Google Ads account. If those searches have meaningful volume in your target countries, Google Ads has buyers to capture, and it's usually the faster, more measurable first channel.

If volumes are near zero, because you're creating a new category or your buyers don't think to search for a solution, Google Ads will struggle. LinkedIn can put your message in front of exactly the roles that should care.

When LinkedIn is worth the higher cost

LinkedIn makes most sense when:

• Deal values are high enough to absorb more expensive clicks and longer cycles
• The buying audience is narrow: specific titles at companies of a specific size
• You're doing account-based marketing, targeting a defined list of companies
• Your buyers don't search, but they'll recognise the problem when they see it

It's a harder sell for low-priced, self-serve products, where the cost of reaching each buyer may exceed what a customer is worth.

How to run LinkedIn without wasting budget

• Define the audience tightly: function plus seniority plus company size usually beats a list of job titles.
• Lead with value, not a demo request. Cold LinkedIn audiences rarely book demos straight from an ad.
• Use Lead Gen Forms carefully. Pre-filled forms convert well, but quality varies; add a qualifying question.
• Retarget people who engaged with your content or visited your site with a stronger offer.
• Judge it over a longer window. LinkedIn often starts the journey that ends with a branded Google search weeks later.

How to run Google Ads for B2B

• Phrase and exact match keywords on category, competitor and problem searches
• Strong negative keyword lists to exclude jobs, free tools, training and students
• Dedicated landing pages per intent
• Conversion tracking on qualified leads, ideally with CRM outcomes imported back into Google Ads

Our guide to Google Ads for SaaS covers the setup in detail.

Running both together

A common pattern that works:

1. Google Ads captures people already searching.
2. LinkedIn reaches the wider buying committee and people not yet searching, with useful content.
3. LinkedIn retargeting brings engaged people back with a demo or trial offer.
4. Branded search on Google grows as LinkedIn builds awareness. Watch it as a sign that LinkedIn is working, even when LinkedIn doesn't get the last click.

Add a "How did you hear about us?" field to your demo form. Self-reported attribution often credits LinkedIn and other awareness channels that click tracking misses.

Frequently asked questions

Is LinkedIn or Google Ads better for B2B?

Google Ads is usually better when buyers actively search for your category or competitors. LinkedIn is usually better when buyers don't search, when the audience is a narrow set of roles, or when deal values justify higher costs for precise targeting.

Why are LinkedIn ads so expensive?

LinkedIn's audiences are professionals targeted by job role, seniority and company, which many B2B advertisers compete for. The cost can be justified when deal values are high and the targeting reaches a buying audience other channels can't isolate.

Should a B2B startup start with LinkedIn Ads or Google Ads?

Check search volume for your category and competitors first. If there's meaningful search demand, start with Google Ads. If there isn't, or if you sell to a narrow set of enterprise roles, test LinkedIn.

Do LinkedIn Lead Gen Forms produce good leads?

They convert well because they're pre-filled from profiles, but quality varies. Adding a qualifying question and following up quickly helps. Compare them with landing page leads on cost per qualified lead.

Can I run LinkedIn Ads and Google Ads together?

Yes, and many B2B companies do. Google captures existing demand, while LinkedIn creates awareness and retargets engaged prospects. Judge LinkedIn partly by growth in branded search and self-reported attribution.
