Which B2B companies TikTok works for, where it wastes money, what the videos need to look like and how to run a fair test before committing a real budget.
Sooner or later, someone in most B2B companies, those selling to other businesses, asks whether you should be advertising on TikTok. The honest answer is that it depends, in ways specific enough to be useful. TikTok can work when your buyers decide largely on their own, such as founders, small business owners, freelancers or ecommerce managers, and when your product can be shown or explained in a short video. It rarely works when you sell to buying committees in large organisations, need to reach named companies or job titles, or sell something nobody wants to hear about in their free time.
Getting this call wrong costs money in both directions. Advertise when your buyers are not open to you there, and you pay for views that never become enquiries; dismiss TikTok when they are, and a competitor gets their attention instead. Even where it fits, TikTok is mainly a way to get known and create demand that other channels then capture, so judge it over months rather than weeks.
This article helps you work out which side of that line you are on. It covers how TikTok differs from other B2B channels, where it tends to work and where it wastes budget, what the videos need to look like, and how to run a test that gives you a clear answer.
TikTok has no professional targeting. You cannot choose people by employer, company size or job title; you choose by country, language, age, interests and behaviour, plus your own customer lists and website visitors. Delivery is then driven by how people respond: the system learns who watches, comments or clicks on your ad and finds more people like them.
That makes the video your targeting. A clip about cutting delivery costs for small webshops will mostly be watched to the end by people who run small webshops, because nobody else cares enough to keep watching. A clip that could be for anyone will be shown to anyone.
The setting is different too. People open TikTok to be entertained or to learn something in their own time, not to research suppliers, so your ad interrupts a personal moment.
TikTok for B2B is not about reaching buyers at work but about reaching them as people, and being worth their personal attention.
Before spending anything, check the audience estimate in TikTok Ads Manager for your countries, languages and the age groups that match your buyers. In smaller European markets, especially with content in the local language, the numbers can be modest, and that limits how much you can sensibly spend.
TikTok tends to work when three things are true: the buyer is an individual who uses the platform personally, the decision is small or quick enough for one person to make, and the product has a story you can see. In practice that points to companies like these:
TikTok can also help a B2B company hire, since many of the people you want to employ use it. That is a different objective with different measures, so keep it separate from your sales tests.
TikTok is a poor fit for complex software or services sold to large organisations, where a committee compares suppliers over months and the person who watches your video is rarely the one who signs. It also struggles in regulated sectors such as financial services, healthcare or legal services, where every claim needs approval and quick, informal videos are hard to produce.
It is the wrong tool for account-based marketing, where you pick specific companies and market to them directly, because you cannot target named companies. It also fails for companies that cannot keep producing new videos: people tire of the same ad quickly on TikTok, so one expensive video will not carry a campaign for long.
A useful test: if your best salesperson would feel awkward explaining your offer to a stranger at a dinner party, TikTok will probably feel the same. If they would enjoy the conversation, there may well be a video in it.
TikTok ads have to feel as if they belong on TikTok, or viewers scroll past before the system can learn anything. That means vertical 9:16 video, natural light and sound, a real person talking to the camera, no stock footage, and an opening that makes sense without any context in the first two or three seconds.
Repurposing a LinkedIn video is one of the most common mistakes. A polished horizontal clip with a logo intro and a voice-over reads as an advert within a second, and people treat it as one. TikTok needs its own brief, its own format and ideally its own on-screen person: your founder, an expert from your team, or a creator who already speaks to your buyers.
Formats that suit B2B include a problem stated in the viewer's words followed by a quick fix, a screen recording of a task before and after, a customer explaining what changed for them, three mistakes people in the viewer's role often make, and a founder answering a real question from the comments. Script the first line hardest, because it decides whether anyone sees the rest. Add on-screen text as well as speech, so the point lands for people watching with the sound off.
Spark Ads let you put paid reach behind organic posts, either from your own account or from a creator's or employee's account with their permission. The post keeps its likes, comments and the person's profile, so it looks native, and you can promote the posts that already did well organically instead of guessing.
Most TikTok tests fail because they are too short, too small or measured on the wrong thing. Decide in advance what you will spend, for how long, and what result would make you continue:
Keep the targeting simple so the videos can do their work: your countries and languages, the age groups that match your buyers, and existing customers excluded. Once the test is under way, add a lookalike of your customer list and retarget people who watched most of a video or visited your site, this time with a more direct offer.
Then judge the result on the whole picture, because TikTok's own reports will miss people who watch on their phone and look you up later on a laptop. Say you spend €4,000 a month for three months and TikTok reports only eight leads, but 'TikTok' starts appearing in the answers to that question, branded searches rise in your test countries and your sales team hears the videos mentioned on calls. That is TikTok doing its job, creating demand that shows up elsewhere, and it deserves a second phase. If none of those signals moves after three months of decent videos, stop and spend the money elsewhere.
If you use TikTok's instant lead forms, add a qualifying question such as company size or role, because forms that open inside the app are easy to fill in on impulse. A smaller number of leads who answered honestly is worth more than a long list your sales team cannot use.
