I. Introduction

Every content creator with a marketing blog has a take on this. LinkedIn for B2B. Google for intent. Run both. Pick one based on budget. The answers are always clean and the recommendations always certain.

The reality is messier and more interesting. This is not a question with a universal answer because the right platform depends on your ICP clarity, your offer type, your sales cycle length, your budget, and what specifically you are trying to get someone to do. Getting it wrong in either direction means spending money showing ads to people who will never buy from you. This blog works through the actual factors that determine where B2B paid spend belongs.

Google Search Ads operate on intent. Someone types a query, and your ad appears in front of that intent signal. The person is actively looking for something. That is a genuinely valuable moment. The problem is that Google has no idea who that person is in a business context. A CFO at a 500-person enterprise and an intern at a startup typing the same search term look identical to Google. You are buying intent without buying qualification.

LinkedIn Ads operate on audience. You define the target: job title, seniority level, company size, industry, geography, specific companies if you are running ABM. The person may not be actively searching for anything. They are scrolling LinkedIn. But you know, with reasonable confidence, that they are a VP of Finance at a 300-person SaaS company. That is qualification without guaranteed intent.

Google gives you intent without identity. LinkedIn gives you identity without intent. Neither platform alone gives you both, which is why the choice between them is never as simple as the content you read about it suggests.

LinkedIn targeting is only as good as your ICP definition. If you are clear on exactly who you sell to, job title, company size, industry, seniority, LinkedIn’s targeting capability is genuinely powerful. If your ICP is vague, you will spend significant budget showing expensive ads to people who match the demographic but have no problem you can solve.

LinkedIn CPC runs between $6 and $12 on average for B2B campaigns in competitive categories, with CPMs rising to $34 per thousand impressions in 2025 according to Dreamdata’s benchmarks. At those rates, an ill-defined audience is an expensive mistake.

Google Search has a different version of the same problem: keyword selection. Broad or poorly considered keywords pull in searchers who have no buying context. Someone searching for ‘marketing automation’ could be a CMO evaluating platforms, a student writing an essay, or a freelancer looking for a tool for a single project. Without a disciplined negative keyword strategy, a significant portion of Google Search spend goes to irrelevant clicks. Negative keywords are not an optional refinement. They are a core part of the campaign structure and teams that treat them as an afterthought are funding non-buyers.

IV. Cost and ROI: What the Data Shows

LinkedIn costs more per click. That is not disputed. The question is whether the quality of what you get justifies the premium.

According to Factors.ai data covering 100+ B2B marketing teams, LinkedIn-sourced opportunities show 28% higher average contract value than Google-sourced ones, and cost per qualified meeting is lower on LinkedIn than Google despite the higher CPC. Dreamdata’s 2026 benchmarks show LinkedIn ROAS at 121% versus Google Search at 67%, with LinkedIn accounting for 41% of B2B paid media budgets, up from 39% the previous year.

The more instructive stat is the halo effect. ICP accounts that were exposed to LinkedIn Ads showed a 46% higher conversion rate on paid search. The two platforms are not competing. For many B2B companies, LinkedIn warms the audience and Google captures the resulting intent. Running only one and attributing all results to it gives you an incomplete picture of what is actually driving pipeline.

V. What Belongs on LinkedIn vs Google by Campaign Type

This is where the decision gets practical. Not every campaign type works equally well on both platforms.

• Events and webinars: LinkedIn. You are promoting a specific event to a specific professional audience. The targeting precision lets you reach the exact seniority and function you want in the room. Google Search ads for a webinar require someone to be actively searching for that specific topic or event, which limits reach significantly.
• Product or service with active search demand: Google Search. If your buyers are actively searching for what you sell, capturing that intent is worth the spend. ‘Marketo consulting agency’, ‘HubSpot implementation partner’, ‘B2B lead generation services’ all have people searching with purchase intent.
• ABM and named account targeting: LinkedIn. If you have a list of 200 target companies and you want decision-makers at those companies to see your content, LinkedIn’s company targeting and account-based features are built for exactly this. Google cannot do it.
• Brand awareness to a defined professional audience: LinkedIn. Broad awareness through Google requires either Search (intent-dependent) or Display (low engagement, mixed quality audience). LinkedIn’s feed puts content in front of a professional audience you can define.
• Retargeting warm website visitors: Both. Google’s retargeting network has broader reach at lower cost. LinkedIn’s retargeting is more expensive but keeps your brand in front of a professional context rather than general web browsing.

VI. The Budget Question and How to Split It

There is no universal percentage. The right split depends on three things: whether your offer has active search volume worth capturing, how precisely you can define your ICP, and what stage of market awareness your buyers are at.

A company selling a known category with established search demand, ‘Salesforce consulting’ or ‘HubSpot implementation’, should weight toward Google Search while using LinkedIn to reach senior decision-makers who might not be searching yet. A company selling something newer or more complex, where buyers may not know what to search for, should weight toward LinkedIn where you can reach the right people and educate them.

The B2B buyer journey has lengthened significantly. Dreamdata’s 2026 data shows an average of 272 days from first touch to closed revenue, with 81% of that journey happening before the sales pipeline even begins. At that length, single-platform attribution is meaningless. The question is not which platform gets credit. It is whether your combined paid presence is reaching the right people at every stage of a journey that spans nearly a year.

The budget split is a secondary decision. The primary decision is whether your ICP is defined precisely enough to use LinkedIn effectively, and whether your offer category has the search volume to make Google Search worthwhile. Answer those two questions and the split becomes clearer.

VII. The Answer Nobody Wants to Give

There is no B2B category where one platform is always the right answer. Any content that tells you otherwise is simplifying a decision that depends on specifics your business context determines.

LinkedIn costs more per click but delivers higher average contract value and better-qualified pipeline for most B2B categories. Google Search costs less per click but requires disciplined keyword and negative keyword management to avoid funding irrelevant traffic. Used together with intent, they complement rather than compete.

The companies wasting the most on B2B PPC are not the ones on the wrong platform. They are the ones with an unclear ICP running on LinkedIn, or no negative keyword strategy running on Google, or attributing all results to whichever platform the last click came from.

At Code and Peddle, our PPC engagements start with ICP and offer analysis before we touch either platform. The targeting strategy is built from the ICP out, not from the platform in. That sequence is what determines whether paid spend drives pipeline or simply drives activity.
