Google Ads vs Meta Ads vs LinkedIn Ads for B2B: which channel does which job

Three channels, three different jobs

The short version:

• Google Ads answers demand. Someone types a problem or a service into a search box, and you show up. It captures buyers who already know what they want.
• LinkedIn Ads creates and shapes demand inside a defined professional audience. You choose job functions, seniority, industries, company sizes or a specific list of companies, and put a message in front of them before they start looking.
• Meta Ads (Facebook and Instagram) reaches people as people. Your buyers are there, but the platform knows them by behaviour and interests far more than by job title. It is broad, relatively inexpensive per person reached, and strong for retargeting and recruitment.

Most B2B organizations do not need all three at once. They need the one that matches where their buyers are in the decision, then a second one once the first is measured and working. The rest of this article compares them on the five things that actually decide the choice.

Intent: who is ready now

Intent is the single biggest difference between these channels.

A search for "commercial HVAC maintenance contract Halifax" or "employment lawyer for a termination" is a buyer telling you, in their own words, what they need. Google is the only one of the three where the person brings the intent to you. If people search for what you sell, Google Search is usually the first place to spend, because those buyers are already in motion.

LinkedIn and Meta are interruption channels. Nobody opens LinkedIn hoping to see an ad for your software or your audit service. That is not a weakness, just a different job: reaching the people who will need you before they search, or who will never search at all because they do not know the solution exists.

Which leads to a useful test. If your category has clear search demand, start with Google. If your buyers do not search for what you do (new categories, problems people do not know they have, very senior buyers who rely on referrals), search will be thin and LinkedIn becomes more important.

Audience quality and targeting

LinkedIn has the most precise professional targeting of the three, because people maintain their own job titles, employers and industries. You can reach operations directors at manufacturers over a certain size in Atlantic Canada, or a named list of target accounts. That precision is what you pay for, and it is why LinkedIn's cost per person reached is usually the highest. In a small region, precise audiences can also be very small, which limits how much you can spend before the same people see your ads too often.

Google targets the search, not the person. You do not know the job title of the person searching, but the words they use often tell you more. The quality control lives in your keywords and in the search terms report, where you exclude the searches that will never buy.

Meta knows a lot about behaviour and interests and little about job titles. You can reach business owners and professionals, but less precisely. Its strengths in B2B are retargeting (reaching people who already visited your site or engaged with you), uploaded contact lists, lookalike-style expansion from good customers, and recruitment, where the audience is broad by nature.

Creative needs

The creative burden differs a lot, and it is a real cost that budgets often miss.

• Google Search is mostly text. The work is in matching ad copy to the search and building a landing page that keeps the promise. Creative fatigue is low, because the audience is new searchers each day.
• LinkedIn needs creative that earns attention from busy professionals in a feed: a clear point of view, a useful document, a short video, a specific claim. Generic corporate imagery is ignored. Small audiences see the same ads repeatedly, so creative needs refreshing.
• Meta moves fastest. Ads compete with friends, family and entertainment. Visuals have to stop the scroll, video tends to matter more, and fatigue sets in quickly. Plan for a steady supply of new variations.

If your team cannot produce fresh creative regularly, that alone is a reason to start with search.

In New Brunswick, add one more consideration: if part of your audience works in French, each channel needs French creative and French landing pages, not translated afterthoughts. That adds real creative workload on LinkedIn and Meta, and it is better planned for than discovered.

Buying cycles and offers

B2B purchases often involve several people over weeks or months. The channel and the offer need to fit that cycle.

Short cycles, urgent needs (a repair, a compliance deadline, a replacement supplier): Google Search with a direct offer to call, book or request a quote.

Long cycles, considered purchases (software, professional services, capital equipment): LinkedIn to reach the buying group early with useful content, Google to capture them when they eventually search, and retargeting on Meta or LinkedIn to stay present in between. The offer at the start is low commitment (a guide, a webinar, a benchmark of their own situation), not "book a demo".

Account-based programs with a defined list of target companies: LinkedIn is the natural fit, because it can target by company.

An illustrative case: a 60-person IT managed services firm in Fredericton serving clinics and professional offices across the Maritimes. People do search for "IT support" plus a city, so Google Search captures that demand first. Once tracking shows which searches become clients, LinkedIn is added to reach practice managers and office administrators at firms that are unhappy with their provider but have not started looking. Meta is used mainly to retarget site visitors and to recruit technicians. Each channel has a different job and a different measure of success.

Measurement differences

Each platform reports its own results, and each tends to give itself credit generously. Add up the conversions all three claim and you will often get more than actually happened.

• Google is the most straightforward: a search, a click, a visit, an inquiry, often in one session. Importing outcomes from your CRM lets it learn which searches become clients.
• LinkedIn influences buyers who often convert later and through another channel, such as a branded search or a direct visit. Judging it only on immediate form fills undervalues it; judging it on everything that happened after an impression overvalues it. Its native lead forms make conversion easy but can lower lead quality.
• Meta has similar view-through and attribution questions, and its pixel-based tracking is affected by browser privacy changes and consent. Server-side connections help recover some of that signal.

The practical answer is to judge every channel on the same outcome in your CRM (qualified opportunities, won revenue) by first source, and to accept that the numbers are estimates. How to measure lead quality from paid campaigns covers the set-up, and how to tell whether your channels work together covers the cross-channel view.

Choosing where to start

Run through these questions in order:

1. Do buyers search for what you sell? If yes, start with Google Search and measure it properly.
2. Can you name the job titles, industries or companies that buy? If yes, and search demand is thin or your cycle is long, add LinkedIn.
3. Do you have site traffic or a customer list to build on? If yes, retargeting on Meta or LinkedIn is usually a cheap, sensible addition.
4. Can you produce new creative every few weeks? If not, stay mostly on search until you can.
5. Can you measure qualified leads by source? If not, fix that before adding a second channel, or you will not know which one is working.

The mistake to avoid is spreading a modest budget across all three from day one. Each gets too little to learn from, and the result is three thin reports and no conclusions. We plan paid advertising across channels as one system, but we usually launch them in sequence for exactly this reason. For sizing the overall spend, see how much an established business should spend on paid ads.
