LinkedIn Ads or Google Ads: which platform for your SaaS

Cost per click is only part of the story. LinkedIn shows high CPCs, often $5.50 to $10, while Google B2B tends to sit between $2 and $10 according to Search Engine Land. On high-intent B2B audiences, the gap narrows significantly.

What matters is cost per lead. LinkedIn runs between $150 and $400 per lead, Google more like $70 to $200 according to Stackmatix. But LinkedIn's native forms convert well, at 2 to 3.5%, and lead quality there is often higher.

Measured against the final customer, our study on CAC by channel puts LinkedIn Ads at around $982 versus $802 for SEA. LinkedIn costs more to acquire, but targets your ICP more precisely.

The real difference isn't price, it's intent. Google captures demand that already exists: the person is searching for your category. If your buyers are already typing queries around your product, start there, it's the best conversion rate.

LinkedIn creates demand: you reach a precise ICP by job title, industry, and company size, even without expressed intent. It's the tool when your product is new or your category isn't being searched for yet.

On budget, the thresholds differ: plan for at least $1,500 to $2,000 per month to properly test Google, and more like $4,000 to $5,000 for LinkedIn. Measure the impact on your acquisition cost with the CAC calculator before committing.

Don't launch both at full throttle at once. Start with the platform that matches your intent: Google if demand already exists, LinkedIn if you need to create it. Gather enough clicks to judge, at least a few hundred dollars' worth, before drawing any conclusions.

Segment so you don't get trapped by the average CAC. A branded campaign shows a ridiculously low cost, a generic campaign blows up: always compare at equivalent intent and audience.

To weigh this against the rest of your levers, also compare SEO or SEA and, if your target is a small number of accounts, ABM or inbound. The full picture is in B2B SaaS acquisition.

Ad platforms are only part of the equation. Before paying for every click, ask yourself whether an organic channel could do the same job for less over time: that's the whole point of the SEO or SEA comparison.

Paid advertising shines for testing fast and for covering demand your organic hasn't captured yet. Seen as an accelerator rather than a sole engine, it still makes sense even on a tight budget.
