Google Ads vs Meta ads vs LinkedIn Ads: Which Is Best for B2B?

For most B2B small businesses, Google Ads is the best place to start, because it puts you in front of people who are already searching for what you sell. Meta Ads (Facebook and Instagram) are usually better for building awareness and retargeting people who already know you, and LinkedIn Ads come into their own when you need to reach specific job titles and can justify a higher cost per lead. The right answer depends on whether your buyers are already looking for you, how much a new customer is worth, and how long your sales cycle is.

This guide compares the three platforms in plain terms, explains how to decide where to put your first budget, and covers the common reasons B2B ads don’t turn into enquiries.

What’s the main difference between Google Ads and Meta ads?

The difference is intent. Google Ads search campaigns show your ad when someone types a search, such as “IT support for small businesses in Glasgow”. That person has a need right now, so a click from them is often worth more. You’re capturing demand that already exists.

Meta Ads show your ad to people as they scroll Facebook or Instagram, based on who they are and what they’re interested in. They weren’t looking for you, so the job of the ad is to catch their attention and start a relationship. You’re creating demand rather than capturing it.

Neither is better in every case. A business selling an emergency service will usually do well on Google, because people search when they have a problem. A business selling something new that people don’t know to search for may find Meta or LinkedIn works better, because there’s little search demand to capture.

How do Google, Meta and LinkedIn Ads compare for B2B?

Google Ads

• Best for: services people actively search for, local B2B services, and buyers comparing suppliers.
• Strengths: high intent, you pay mainly for clicks on search ads, and you can control exactly which searches you appear for using keywords and negative keywords.
• Watch out for: competitive keywords can be expensive, and broad keyword settings can pull in irrelevant searches if nobody checks the search terms report.

Meta ads (Facebook and Instagram)

• Best for: raising awareness, retargeting website visitors, promoting events or offers, and reaching business owners in their personal feeds.
• Strengths: large audiences, strong visual formats such as video and carousels, and lead forms that open inside the app so people don’t have to leave Facebook or Instagram.
• Watch out for: you can’t target by job title in the way LinkedIn allows, and quick in-app lead forms can bring in lower-quality enquiries unless you ask a qualifying question.

LinkedIn Ads

• Best for: reaching decision-makers by job title, seniority, industry or company size, and selling higher-value services with longer sales cycles.
• Strengths: the most precise professional targeting of the three, and Lead Gen Forms that can fill in details from a person’s LinkedIn profile.
• Watch out for: clicks and leads usually cost more than on Google or Meta, so it suits businesses where one new client is worth a lot.

Paid LinkedIn campaigns also work well alongside organic activity. If you’re new to the platform, our guide to promoting your business on LinkedIn covers the free side first.

Which platform should a small B2B business start with?

Work through these four questions before you spend anything.

1. Do people search for what you sell? Type the phrases your customers would use into Google. If competitors are already running ads there, there’s search demand, and Google Ads is usually the first step.
2. Can you describe your buyer by job? If your ideal customer is “finance directors at firms with 50 to 200 staff”, LinkedIn’s targeting is hard to match. If it’s “anyone who runs a small business”, Meta or Google may reach them more cheaply.
3. What is a new customer worth to you? Work out the typical value of a client over a year or more. A high-value service can afford a higher cost per lead, which opens up LinkedIn. A lower-value service needs cheaper clicks.
4. How long does it take to win a client? Long sales cycles need people to see you more than once. That’s where Meta and LinkedIn retargeting help, reminding website visitors about you while they decide.

For many small businesses the answer is to start with one platform, prove it works, then add a second. Splitting a small budget across three platforms at once usually means none of them gets enough data to improve.

How much should a small business spend on PPC?

There’s no single right figure, because click costs vary widely by industry, location and competition. A better approach is to work backwards from what a customer is worth and how many enquiries you need.

• Decide how many new enquiries a month would make the ads worthwhile.
• Use the platform’s planning tools, such as Google’s Keyword Planner, to see likely click costs for your terms.
• Start with a budget you could afford to lose while you test, and give it long enough to collect useful data before judging it.
• Review cost per enquiry and cost per new client, not just clicks, and move money towards what works.

It also helps to understand how budgets behave. Google says that on a given day a campaign might spend up to twice its average daily budget, but over a month you won’t be charged more than 30.4 times the daily budget. You can read the detail in Google’s guide to daily budgets. Ad spend is paid to the platform and is separate from any management fee.

Why don’t my B2B ads turn into enquiries?

When ads get clicks but no enquiries, the platform is rarely the only problem. These are the most common causes.

• Sending traffic to the home page. People who click an ad about one service should land on a page about that service, with a clear way to get in touch.
• No conversion tracking. If form submissions and calls aren’t tracked, neither you nor the platform’s bidding can tell which ads bring in leads.
• Targeting that’s too broad. On Google, check the search terms report and add negative keywords. On Meta and LinkedIn, tighten the audience to the people who actually buy.
• A slow or confusing website. Most social clicks happen on a phone. If the page is slow, hard to read or the form is long, people leave. A well-built website designed to convert makes every pound of ad spend work harder.
• Asking for too much too soon. B2B buyers often aren’t ready to book a sales call from one ad. Offering a guide, a checklist or a short consultation can be an easier first step.
• No follow-up. Leads go cold quickly. A CRM that alerts you to new enquiries and reminds you to follow up turns more of them into clients.

Should paid ads replace SEO?

No. Paid ads bring traffic as soon as they’re switched on and stop when you stop paying. SEO takes longer but keeps working over time, and it now also affects whether AI tools mention you. Our guide to showing up in ChatGPT and Google AI Overviews explains that side. Many businesses use ads to bring in enquiries now while SEO builds in the background.

Frequently asked questions

Is Google Ads or Meta ads better for B2B?

Google Ads is usually better when your buyers already search for your service, because you reach them at the moment they need you. Meta Ads are usually better for awareness and retargeting. Many B2B businesses start with Google and add Meta retargeting later.

Is LinkedIn advertising worth it for a small business?

It can be, if you sell a high-value service to a clearly defined group of professionals. LinkedIn clicks tend to cost more than on other platforms, so it suits businesses where one new client covers the cost of many leads.

How long should I run ads before judging them?

Give a new campaign enough time to collect meaningful data, often a few weeks, before making big decisions. Small daily tweaks too early can stop the platform learning which audiences and searches work.

Can I run PPC myself?

Yes, all three platforms let you set up your own account. The risk is wasted spend from loose targeting, missing tracking or campaigns nobody checks. If you don’t have time to manage them weekly, it’s usually worth getting help.
