Google Ads or Meta for a B2B SME: how to choose

Google Ads or Meta for a B2B SME: the question comes up as soon as you want to buy visibility, and the two platforms do not do the same job. Google Ads shows an ad to someone typing a search; Meta shows it, on Facebook and Instagram, to someone who was not looking for anything. This comparison starts from that difference to decide where to begin; it adds to our articles on online advertising.

What is the difference between Google Ads and Meta in B2B?

On the Google Search Network, the ad answers an intent: the prospect describes their own need, and you pay to appear on those words. On Meta, you choose an audience, and the ad has to arouse an interest that did not exist a second earlier.

In B2B, the gap matters more than elsewhere: someone who types “ambulance scheduling software” is already comparing offers, while someone scrolling through Instagram may have the authority to sign but is not thinking about it at that moment.

How can you tell whether your customers are looking for you on Google?

Before choosing, measure the demand. Google’s Keyword Planner shows, for each keyword idea, the average number of monthly searches and the top-of-page bid, as a low and a high range. You can set it to a location (a country, a region, a city) and to a language: set it to your own market, not to the whole world.

The method has three steps:

1. 01Note.

   Write down the words your customers really use, in their emails and their tenders, rather than the ones in your brochure.

2. 02Measure.

   Enter the words you noted in the tool, with your country and your language, then read the volumes and the bids.

3. 03Sort.

   Separate the searches that describe a purchase (“software”, “supplier”, “quote”) from those looking for information or a job.

If purchase searches exist, start with Google Ads on those queries: it is the demand closest to a signature. If they are rare, the demand still has to be created, and that is the territory of Meta or LinkedIn.

Can Meta bring in B2B customers?

Yes, when your buyer is recognisable by a profession or a type of company, and when the offer can be understood in a few seconds: a training course, a tool for a specific profession, a trade show. Two settings make the difference in B2B.

The form. According to Meta’s documentation, its lead form ads are optimised for the volume of requests by default. A setting for higher intent adds a step where the person reviews and confirms their answers before sending: fewer requests, but from people who have read what they are sending. For a sale that is signed in a meeting, this is the setting you need, or sending people to the form on your own website, which records each request with its source.

Your website visitors. Meta also lets you reach again the people who have visited your site or taken an action on it, using its pixel, and keep them in the audience for 1 to 180 days depending on the setting. In B2B, this use is defensible: showing a demo page again to someone who has already read it, rather than to a stranger.

This pixel is an advertising tracker. The CNIL’s rules on cookies (the CNIL is France’s data protection authority) require prior consent for personalised advertising trackers and social network trackers: the pixel must only fire after the visitor has agreed, and the audience will only include those who have. Expect it to be smaller than your traffic.

What if the buyer is defined by their job title?

Many B2B purchases are better described by a job function than by an interest: a finance director, a purchasing manager. Two platforms target on these criteria.

LinkedIn. Its ads rely on the data its members declare: according to LinkedIn, job title, company, industry and seniority level. It is the most direct route to a given job function. Before committing to it, compare the estimated cost of a request with that of a Google search on the same need.

Microsoft Ads. Less well known, Microsoft Advertising, the ad platform of Microsoft and Bing, lets you target using LinkedIn profile information: company, industry, job function (sales, accounting, purchasing). This targeting exists for search campaigns, audience campaigns and Performance Max, where it was not yet open to everyone in October 2026. You set a bid adjustment per target: you can bid higher when the search comes from a person whose profile matches. A stated intent and a known job function in the same bid: that is the appeal of Microsoft Ads in B2B.

How do you choose, step by step?

1. Describe the buyer and measure the demand: their job function, their company and the words they use, then the volume of those words in the planning tool, set to your market.
2. If the search exists, start with Google Ads, on purchase queries only. Add Microsoft Ads if the buyer’s job function matters as much as their search, and if that targeting reaches your market.
3. If it does not exist, test Meta with a higher-intent form and retargeting of website visitors, or LinkedIn if the buyer is defined first by their job title.
4. Check the tracking before you spend. Every request must arrive with its source recorded, including the campaign and the page it came from: without it, no acquisition decision is possible.
5. Judge on sales, not on forms. Send the CRM stages back to the platform, as detailed in our guide to sending sales from your CRM back to Google Ads, then compare the cost per qualified request after at least one sales cycle.

Advertising also works as a market test: before translating a site for a new country, a small campaign on its queries, in its language, quickly tells you whether the demand exists and what it costs, where SEO takes a long time to answer.

Where to start

Open the planning tool with about ten words your customers really use: the answer will tell you whether to start with Google Ads, or whether you need to create the demand with Meta or LinkedIn.

To choose the platform and set up tracking before committing a budget, tell us about your market and your customers: we start from what they are already searching for. Once the platform is chosen, our digital marketing in one block offer makes it work together with SEO and the CRM: each signed sale tells the campaigns where to bet.
