LinkedIn Ads vs Google Ads for B2B: Which Should You Use?
LinkedIn Ads vs Google Ads for B2B: Which Should You Use?
LinkedIn Ads and Google Ads do opposite jobs. Google Ads captures demand that already exists, reaching people who are actively searching for a solution. LinkedIn Ads generates demand, reaching the right professionals by job title and company before they start searching. Google usually shows a lower cost per lead, but it is capped by how many people are searching; LinkedIn costs more but reaches buyers who are not in-market yet. This guide compares the two on cost, targeting, and intent, shows how to split budget, and explains the signals that tell you when to shift budget from one to the other.
Key takeaways
- Google Ads captures existing demand (people searching); LinkedIn Ads generates demand (target by who people are).
- Google usually has a lower cost per lead, around $70, versus roughly $150 or more on LinkedIn, but it is capped by search volume.
- LinkedIn targets by verified job title, company, and seniority; Google targets by the keywords people search.
- Watch saturation signals: when Google impression share is maxed and cost per lead is rising, shift budget to LinkedIn to create new demand.
- They are not either-or: most B2B programs run both, Google to capture demand and LinkedIn to create it.

| Conversion rate | around 2.7% | around 7.5% |
| Reach limit | Your whole target market | Capped by search volume |

The core difference
This is the whole decision in one line: Google captures demand, LinkedIn creates it. On Google, you bid on keywords, so you reach people the moment they search for your category. That is powerful, but it only works if people are already searching, which caps your reach at existing demand. On LinkedIn, you target by who someone is (job title, company, seniority, and industry), so you can reach the right buyer long before they ever type a query.
So the platforms are not competing for the same moment. Google harvests buyers at the bottom of the funnel; LinkedIn builds awareness and pipeline higher up, among people who will search later or never search at all.
Cost comparison
Google usually looks cheaper per lead, but it is buying a different, scarcer moment. Google’s conversion rate is higher (around 7.5% versus 2.7%) because the traffic is already searching with intent, which is also why its cost per lead is lower. LinkedIn’s leads cost more because you are reaching people before they are in-market.
The trade-off is reach. Google can only sell you as many leads as there are searches, so once you capture the existing demand, there is nowhere to scale. LinkedIn can reach your entire target market whether or not they are searching today, which is how you grow demand beyond what search can supply.
Targeting and intent
Google targets by keyword, so it captures active searchers, but a keyword cannot tell you the person’s job or company, so you also pay for non-decision-makers and researchers. LinkedIn targets by role, so you reach the exact seniority and companies you sell to, which is what account-based marketing needs, at the cost of reaching people who are not actively looking yet.
In short, Google gives you intent without identity, and LinkedIn gives you identity without intent. The best B2B programs use both signals rather than forcing a choice.
When to use each, and when to shift budget
Choose by sales cycle, deal size, budget, and whether demand already exists. Use Google when there is real search volume for your category, the sales cycle is short (under about three months), and budget is limited (under roughly $3,000 a month). Use LinkedIn when deal values are high (around $10,000 or more), the sales cycle is long (six months or more), several stakeholders are involved, and budget supports about $5,000 a month or more.
The more useful question for a running program is when to shift budget between them. Lean more into Google while you still have unused search impression share and your cost per lead there is stable, because that is cheap demand left on the table. Shift budget toward LinkedIn when your Google impression share is maxed out, non-branded CPCs are climbing, and cost per lead is creeping up, all signs you have captured the demand that exists and now need to create more. Review this mix quarterly, not yearly, because saturation changes as you scale.
How to split budget across LinkedIn and Google
For most B2B programs with enough budget, the answer is both. A common split is roughly 40% to LinkedIn and 40% to Google, with the rest on retargeting and testing. Let Google capture the demand that already exists so you never miss an active searcher, and let LinkedIn create demand among the right accounts so the search pipeline keeps filling.
Measure each on pipeline, not on its own cost per lead, because Google’s cheaper leads and LinkedIn’s demand creation are doing different jobs that only add up at the pipeline level (the reporting framework shows how). If you want help splitting budget between LinkedIn and Google by pipeline, you can book a demo.
Frequently Asked Questions
Q1. Is LinkedIn or Google better for B2B ads?
Neither is simply better; they do opposite jobs. Google captures people already searching for your category, usually at a lower cost per lead. LinkedIn reaches the right decision-makers by job and company before they search. The strongest B2B programs run both, using Google to capture demand and LinkedIn to create it.
Q2. What is the difference between LinkedIn Ads and Google Ads?
Google Ads captures demand: you bid on keywords to reach people actively searching. LinkedIn Ads generates demand: you target by verified job title, company, and seniority to reach the right buyers before they search. Google gives you intent without identity; LinkedIn gives you identity without intent.
Q3. Which is cheaper, LinkedIn Ads or Google Ads?
Google is usually cheaper per lead, around $70 versus roughly $150 or more on LinkedIn, with a higher conversion rate because the traffic is already searching. But Google is capped by search volume, while LinkedIn can reach your whole target market. Judge both on pipeline, not just cost per lead.
Q4. When should you use Google Ads instead of LinkedIn for B2B?
Use Google when there is real search volume for your category, the sales cycle is short (under about three months), and budget is limited (under roughly $3,000 a month). Capturing existing demand through search is the fastest path to return when people are already looking for what you sell.
Q5. When should you use LinkedIn Ads instead of Google for B2B?
Use LinkedIn when deal values are high (around $10,000 or more), the sales cycle is long (six months or more), several stakeholders are involved, and budget supports about $5,000 a month or more. You need to reach and warm a buying committee that is not actively searching yet.
Q6. How do you know when to shift budget from Google to LinkedIn?
Shift toward LinkedIn when your Google impression share is maxed out, non-branded CPCs are rising, and cost per lead is creeping up. Those are signs you have captured the existing demand and need to create more. While Google still has unused impression share at a stable cost per lead, keep funding it first.
Q7. Why is LinkedIn cost per lead higher than Google?
Because LinkedIn reaches people before they are in-market, while Google reaches people already searching with intent. Intent-driven traffic converts at a higher rate (around 7.5% versus 2.7%), so Google’s cost per lead is lower. LinkedIn trades a higher cost for the ability to reach buyers who are not searching yet.
Q8. How do you split budget between LinkedIn and Google Ads?
With enough budget, split it roughly evenly, for example about 40% to each with the rest on retargeting and testing. Let Google capture existing demand and LinkedIn create new demand among your target accounts, then shift budget toward whichever is producing more qualified pipeline, reviewed quarterly rather than yearly.
