Google Ads vs LinkedIn Ads for B2B

This comparison gets written badly more often than almost any other in B2B marketing — usually as a features table with no actual recommendation at the end.

Here's the direct version: what each platform actually costs, why the cost gap exists, and a real verdict for your specific situation rather than "it depends" dressed up as analysis.

The comparison, above the fold

*Global/US benchmark figures from published 2025 research, not Indian data — treat the ratio between the two platforms (LinkedIn costing several times more per lead) as the reliable signal, not the exact rupee amount. Absolute costs in an Indian market typically run lower for both platforms; the relative gap tends to hold.

Why the cost gap exists

This isn't LinkedIn being badly run or overpriced — the gap reflects what each platform is actually selling you.

Google Ads shows your ad to someone who already typed a query related to what you sell. You're capturing demand that already exists, which is cheaper because the hard part — realising they have a problem — already happened before your ad appeared.

LinkedIn Ads targets people by who they are — job title, seniority, company size, industry — regardless of whether they're actively searching for anything today. You're paying to reach the right person, not to catch existing intent, which costs more precisely because it's doing more work: creating awareness of a problem, not just answering a search.

Where Google Ads wins

• Your buyers already search for what you sell. If "project management software for construction" gets typed into Google regularly, that intent is worth capturing directly.
• Sales cycles are short. Under about three months, LinkedIn's longer nurture-oriented targeting has less time to pay off.
• Budget is tight. A lower cost per click and cost per lead means a smaller monthly spend can still generate a meaningful volume of leads.
• You need leads this month. Search intent converts faster because the buyer is further along already.

Where LinkedIn Ads wins

• Deal value is high. A $150–400 cost per lead is easy to justify against a five- or six-figure contract; much harder against a low-value transaction.
• Sales cycles run long. Six months or more gives firmographic targeting and nurture content time to build the relationship search intent alone can't.
• Multiple stakeholders decide. LinkedIn's targeting can reach a buying committee by role — something keyword search targeting cannot do directly.
• The category needs educating. If nobody's searching for your category yet because it's new or unfamiliar, you can't capture search intent that doesn't exist — you have to create it.

Ad formats worth knowing

Google's formats are largely search and display — text ads matched to queries, or image ads matched to audience and placement. LinkedIn has leaned into content-native formats: video, carousel ads, and Thought Leader Ads (ads boosted from a real person's post rather than a brand page), which some reported data shows outperforming standard single-image ads by more than 2x on click-through rate. If you're testing LinkedIn for the first time, a Thought Leader Ad from a genuine executive post is a reasonable starting format rather than a traditional brand ad.

Two worked scenarios

These are illustrative, not real client data — but they show how the decision actually plays out.

Scenario one: a project management tool for construction firms, ₹15,000/month subscription. Buyers already search "construction project management software" and similar terms. Deal value is moderate, and the sales cycle is typically a few weeks — someone signs up, tries it, converts. This is a Google Ads-first situation: the demand already exists, and the deal size doesn't justify LinkedIn's higher cost per lead.

Scenario two: an enterprise ERP implementation, six-figure annual contracts. Almost nobody searches "ERP implementation for mid-size manufacturers" with real buying intent — the decision starts with awareness, involves a CFO, an IT head and a plant manager, and takes four to nine months to close. This is a LinkedIn-first situation: the higher cost per lead is easily justified by the deal size, and firmographic targeting can reach exactly the three roles that need to be in the room.

Can I use the same creative on both platforms?

Not well, and it's a common mistake when a team is testing both for the first time. Google Ads text ads are built around matching a specific search query — the message needs to mirror what was typed. LinkedIn ads perform better when they read like content a real person would engage with on a feed, not a search-result headline. Repurpose the underlying offer and value proposition, but write the actual copy separately for each platform.

Retargeting: where the two platforms work together

Even when one platform wins the initial budget argument, retargeting is where they complement each other rather than compete. A visitor who clicked a Google Ads search result but didn't convert can be retargeted with a LinkedIn ad that reinforces the message to the right job titles at their company — useful specifically because it reaches a *person*, not just a browser that visited a page. This is a smaller, cheaper layer worth testing even on a modest combined budget, well before you're ready to run both platforms at full scale.

Why a simple last-click comparison misleads you

If you compare these two platforms purely on their own reported conversions, LinkedIn will almost always look worse than it actually is.

Google Ads tends to sit closer to the end of a buyer's journey — capturing someone who's already decided to look — so its last-click conversions look clean and directly attributable. LinkedIn's job is often earlier: putting your brand in front of a buying committee weeks or months before anyone searches for anything. A prospect might see a LinkedIn ad in March, then convert from a Google search in June with no obvious link back to the LinkedIn touch — but the LinkedIn ad may well be why they searched at all. Judging LinkedIn purely on its own last-click number under-credits exactly the kind of long-cycle, multi-stakeholder deal it's actually good at influencing. A multi-touch or data-driven attribution model in GA4, rather than last-click, gives a fairer read on both platforms' real contribution.

Where to start your budget, if you're testing for the first time

There's no single right number — it depends on your deal size and how quickly you need signal — but a few directional starting points for an Indian B2B team new to either platform:

• Google Ads test: enough budget to gather a meaningful number of clicks on your core terms within four weeks — for most niche B2B categories, that means keeping the keyword list tight rather than spreading a small budget across dozens of broad terms.
• LinkedIn Ads test: because cost per click and cost per lead both run higher, a LinkedIn test needs a longer runway — six to eight weeks is more realistic than four — and a narrower, more precisely defined audience (a specific job title and company size range) rather than a broad "marketing professionals in India" targeting net that burns budget on the wrong seniority.
• Either way, decide the "kill or keep" threshold before you start, not after you've already spent the budget and are emotionally invested in making it work — a specific number ("kill if cost per qualified lead exceeds ₹X after the full test window") decided in advance, not a gut feeling made under pressure once the spend is already committed.

What actually happens once you have data

Run a modest test on both — four to six weeks is usually enough to see a directional signal — and let cost per qualified lead (not cost per click, not cost per raw lead) decide where the next month's budget goes. A cheap lead that never becomes a customer isn't actually cheap.

Track the full path, not just the ad platform's own reported conversions: a lead can look cheap in-platform and still turn out expensive once you account for how many actually reach a sales call. This is exactly what a properly configured GA4 setup is for — without it, you're comparing platforms on numbers neither of them can be fully trusted to report accurately about the other.
