## Short answer

Google Search and LinkedIn are sequential, not alternative. Search captures buyers already looking, with CPCs from 5 to 80 dollars and cost per lead typically 80 to 400 dollars, and it is measurable within weeks. LinkedIn creates demand among people not searching, at 8 to 20 dollar CPCs and 120 to 600 dollars plus per lead, and needs a longer read. Start on search, exhaust the in-market volume, then add LinkedIn once ACV clears roughly 25,000 dollars.

## Key takeaways

- Capture demand on search before creating it on LinkedIn. Cheaper per opportunity and far easier to attribute.
- LinkedIn earns its place above roughly 25,000 dollars ACV or when the buying committee never searches for your category.
- Minimum viable LinkedIn test is about 15,000 dollars over eight weeks. Below that you are buying noise, not a signal.
- LinkedIn demand creation shows up as branded search, so measure it with a geo-split brand search lift test.
- Search lead quality problems are usually a negative keyword problem, not a channel problem.
- Neither channel fixes a weak offer. A demo request form on a 300 dollar product will fail on both.

Every quarter a SaaS marketer is told LinkedIn is where B2B lives, spends 8,000 dollars over six weeks, gets eleven leads, two of which have a real company email, and concludes the channel is broken. It isn't. They ran it in the wrong order.

The two channels do different jobs and the order matters more than the choice.

## Which channel does which job?

Search captures demand that already exists. LinkedIn creates demand among people who don't know they have the problem yet. Everything else about the comparison follows from that one difference.

The creative row is underrated as a cost. Google search ads run for months without fatigue because each impression goes to a different person mid-search. LinkedIn hits the same 12,000 people repeatedly, and frequency above roughly 6 in 30 days starts to actively harm you. That's a designer and a copywriter on retainer, which belongs in the channel's cost, not in a separate line.

## Why search comes first, almost always

Because capturing existing demand is cheaper than manufacturing new demand, and because you can tell within a month whether it's working. Both of those matter more at Series A than the ceiling on the channel does.

Run the numbers with real inputs. A category CPC of 22 dollars, a 6 percent landing page conversion rate to demo request, gives roughly 370 dollars per demo request. If 45 percent of those are qualified, that's about 815 dollars per opportunity. On a 30,000 dollar ACV with a 22 percent win rate, each opportunity is worth 6,600 dollars of expected revenue. That works comfortably.

Now LinkedIn on the same product. 14 dollar CPC, 4 percent conversion on a gated report, 350 dollars per lead, but only 20 percent qualify, giving 1,750 dollars per opportunity. Still positive at 30,000 dollars ACV. Run the same maths at 6,000 dollars ACV and LinkedIn is underwater while search still works. That's the crossover, and it's why ACV is the variable that decides.

Before declaring search exhausted, check your impression share on your core non-brand terms. If it is under 70 percent, you have not run out of search volume, you have run out of bid. Adding a channel when you are leaving impressions on the table is the most expensive mistake in paid media.

Read [SaaS PPC budget allocation](/guides/saas-ppc-budget-allocation/) for how to stage this properly across a year, and the ranges in [SaaS PPC benchmarks](/research/saas-ppc-benchmarks/) to sanity check your own numbers before you conclude anything.

## When LinkedIn earns the budget

Three conditions, any one of which justifies it. Two of which are common and one of which is rarer than people think.

First, you've genuinely exhausted search. Impression share above 85 percent on your money terms, you've mined competitor and alternatives queries, and adding budget just raises CPC without adding clicks. That's a real ceiling and LinkedIn is the natural next move.

Second, ACV above roughly 25,000 dollars. The arithmetic above starts working, and the value of reaching a VP who isn't searching goes up with the size of the deal they control.

Third, and this is the one people overclaim, your buyer genuinely doesn't search. Real cases exist: category-creation products, compliance tools bought reactively, anything where the economic buyer is a CFO who delegates all software research. Vanta had a version of this problem early on, because nobody searches for a product category they've never heard of. But most companies claiming this actually have search demand they haven't looked for properly.

Pull the queries your existing customers used to find you from Search Console, and check the search volume on the problem, not the solution. People searching 'how do I get SOC 2' are in market even though nobody searches 'compliance automation platform'.

## Running both: where LinkedIn shows up as branded search

LinkedIn's effect on pipeline mostly arrives disguised as another channel. Someone sees your ad four times over three weeks, never clicks, then Googles your brand name and converts. Last-touch gives all the credit to branded search, and LinkedIn looks like a failure.

This is not an attribution nuance to hand-wave past. It's the difference between killing a working channel and scaling it.

**Running a brand search lift test**

You'll also want [offline conversion tracking for SaaS ads](/guides/offline-conversion-tracking-for-saas-ads/) running before any of this, because optimising either channel to form fills rather than closed revenue is how you end up with a beautiful CPL and no pipeline. Push closed-won back to both platforms from your CRM.

## Where each channel actually fails

Search fails on lead quality when your negative keyword list is thin. Students, job seekers, competitors doing research and people searching "free" all cost you money, and the fix is a maintained exclusion list rather than a channel change. Start from the [SaaS negative keyword list](/templates/saas-negative-keyword-list/) and add to it weekly for the first quarter.

Search also fails when your category has no search volume, which is genuinely fatal rather than fixable. And it fails when CPCs in your category are set by venture-funded competitors bidding past rationality, which happens in CRM, project management and HR tech. Check what you can afford with the [SaaS max CPC calculator](/calculators/saas-max-cpc-calculator/) before you commit.

LinkedIn fails in more ways. It fails when the audience is under 30,000 people, because you'll hit damaging frequency in a fortnight. It fails when creative is refreshed quarterly instead of monthly. It fails when the offer is a demo request to a cold audience, which converts at a rate that makes the whole channel look broken. And it fails when the team measures it on last-touch after 30 days.

| Failure mode | Channel | Fix |
|---|---|---|
| Job seekers and students clicking | Google | Negative keywords, weekly review for 12 weeks |
| Great CPL, no pipeline | Both | Offline conversion import, optimise to opportunity |
| Audience burnout by week three | LinkedIn | Wider audience or monthly creative refresh |
| Demo requests at $900 each | LinkedIn | Change the offer. Content first, demo later |
| Rising CPC, flat clicks | Google | You are at the ceiling. This is your LinkedIn signal |

## What to run at each stage

A rough progression that holds for most mid-market SaaS companies. Adjust for ACV, obviously.

| Stage | Monthly paid budget | Split | What to prove |
|---|---|---|---|
| Pre product-market fit | $0 | None | Nothing. Go talk to customers |
| $1M to $3M ARR | $3K to $10K | 100 percent Google Search, brand plus top 15 terms | That a paid demo request converts to revenue at a viable CAC |
| $3M to $10M ARR | $10K to $40K | 80 percent search, 20 percent LinkedIn retargeting only | That search is near its ceiling |
| $10M+ ARR with $25K+ ACV | $40K+ | 55 percent search, 35 percent LinkedIn, 10 percent review sites | That demand creation moves branded search |

Notice LinkedIn enters as retargeting first. Retargeting site visitors on LinkedIn is the cheapest possible version of the channel, converts far better than cold, and gives you a read on creative before you spend on cold audiences. Both channels need a copy system behind them, and the [SaaS ad copy templates](/templates/saas-ad-copy-swipe-file/) are a faster start than a blank doc.

Deeper mechanics live in [Google Ads for SaaS](/guides/google-ads-for-saas/) and [LinkedIn Ads for SaaS](/guides/linkedin-ads-for-saas/), and the wider channel picture sits in [SaaS PPC and paid ads](/saas-ppc/).

## The thing to do next

Pull your non-brand impression share this afternoon. If it's under 70 percent, close the LinkedIn tab and go raise bids on the terms where you're losing impressions to budget. That's cheaper pipeline than anything LinkedIn will give you this quarter.

If you're above 85 percent and CPCs are climbing without extra clicks, budget 15,000 dollars for an eight-week LinkedIn test with retargeting plus one cold audience, and set up the geo holdout before you launch rather than trying to reconstruct it afterwards.

## Frequently asked questions

### Is Google Ads or LinkedIn better for B2B SaaS?

Google Ads is better first for almost every SaaS company, because it reaches people already looking for a solution and produces a measurable signal within four to six weeks. LinkedIn becomes worth adding when in-market search volume is exhausted, when average contract value clears roughly 25,000 dollars, or when the economic buyer never types your category into Google.

### Why is LinkedIn cost per lead so much higher than Google's?

Because you are interrupting someone rather than answering them. LinkedIn impressions reach people with no active need, so a much larger share of impressions are wasted on people who will never buy. You are also paying for precise firmographic targeting that Google cannot offer, and LinkedIn's auction has fewer advertisers subsidising cheap inventory.

### What is the minimum budget to test LinkedIn Ads for SaaS?

Around 15,000 dollars across eight weeks, split across two audiences and three creative angles. Smaller tests produce numbers with confidence intervals wide enough to justify any conclusion you already wanted. If you cannot commit that, put the money into search and revisit LinkedIn later.

### How do you measure LinkedIn's effect on branded search?

Run a geo holdout. Split comparable regions, run LinkedIn in one set and not the other for six to eight weeks, and compare branded search impressions and direct traffic. It is imperfect and needs enough volume to read, but it beats last-touch attribution, which will always credit the branded search click and never the LinkedIn impression that caused it.

### Should a pre-revenue SaaS startup run either channel?

Usually neither. Paid channels amplify an offer that already converts. Before spend, get to a point where you know your trial-to-paid rate and your landing page converts visitors from any source at a rate you can defend. Otherwise you are paying to learn something a hundred sales calls would teach you for free.

### Do LinkedIn lead gen forms produce worse leads than landing pages?

They produce more leads at a lower cost per lead and a lower rate of qualification. The prefilled form removes the friction that was filtering people out. Use them for content offers where volume is the point, and send demo requests to a real landing page where the friction is doing useful work.
