B2B buying intent: is LinkedIn enough to detect it?

For most B2B companies, the first answer is yes: LinkedIn is the best source of buying signals for reaching a decision-maker. But “the best” doesn’t mean “the only one”. Depending on your target and your offer, some of the most useful signals are published elsewhere: in a customer review, a question on a forum, a job posting, a piece of regional press, a new page on a website.

The real question, then, isn’t “LinkedIn or not”, but: where does your prospect leave a trace of the problem you solve?

Why does LinkedIn remain the top source of B2B signals?

For two reasons. First, B2B decision-makers are there, with their job title and company: you know who’s speaking, which lets you qualify the signal. Second, it’s the only major network where you can publicly see who reacts to what.

On LinkedIn, two families of signal coexist:

• Posts: a new appointment, a hire, a new site, a funding round, a leader sharing a difficulty.
• Interactions: a decision-maker liking or commenting on a post about your topic, reacting to a competitor’s content, engaging with a webinar.

Interactions are what other networks no longer give you. Likes have been private on X since June 2024, invisible on YouTube and TikTok, and votes are anonymous on Reddit. On those platforms, interest only shows up in comments and public questions. The detail is on our LinkedIn buying signals page.

What doesn’t LinkedIn show you?

LinkedIn has its own blind spots, and it’s worth knowing them before you promise anything:

• A page’s follower list is only visible to its admins.
• An event’s full attendee list is only visible to organisers and attendees. You can spot people reacting or announcing they’re attending, not the hidden list.
• Nothing private: no messages, no “who viewed your profile”, no site visitors.
• Restricted profiles sometimes show up as “LinkedIn Member”: you can’t contact them.

And above all, LinkedIn only shows what happens there. A hotel racking up negative reviews about a specific problem will never mention it on LinkedIn.

How do you know if your target is really on LinkedIn?

Run a simple test before choosing your sources. Take ten recent customers, the ones you’d like more of, and look up each decision-maker on LinkedIn.

• If almost all of them have an up-to-date profile and post or react from time to time, LinkedIn will be enough to start with.
• If they have a profile but never use it, publication signals (hires, new appointments) will still be useful, but interactions will be rare.
• If half of them have no profile, your target lives elsewhere. That’s often the case for hotels, restaurants, shops and tradespeople.

This test takes ten minutes and saves you months of prospecting on a network your customers never open.

When should you look for signals elsewhere?

1. Your target barely uses LinkedIn. Hotels, restaurants, shops, tradespeople, consumer brands: their leaders post elsewhere, or not at all.
2. The problem you solve shows up in customer reviews. A business whose customers complain specifically about what you fix is a prospect, and the review is dated.
3. Your target asks its questions on forums. Technical teams ask for advice or look for an alternative to a tool on public forums.
4. The signal is a job posting. Many hires are only published on job boards or a careers page.
5. The decision runs through the press. A new factory, an acquisition, a funding round: regional and trade press announce these, sometimes before LinkedIn.
6. The project shows up on the company’s website. A “become a reseller” page, a new language, a new location.

Which sources, for which signals?

Source	Typical signal	Who it suits	Limit
Google reviews, Trustpilot	A wave of reviews about the same problem, replies that stop	Suppliers to hotels, restaurants, shops, ecommerce	You can’t see how the problem was handled privately
Public forums (Reddit)	A question about a tool, looking for an alternative	Software vendors, tech providers	Pseudonyms: you need a clue to link the question to a company
Public Facebook groups	“Does anyone know a good…?”	Suppliers to tradespeople, freelancers	Private groups, the majority, are out of reach
Instagram, TikTok	Opening, renovations, product launch	Suppliers to hospitality, consumer brands	Likes aren’t usable, only posts and comments
Job postings	A role that announces a project (export, ERP, first salesperson)	Almost every B2B provider	Ads can be stale: you need to date them
Press	Funding, factory, acquisition, new leader	Recruitment, property, consulting, insurance	Paywalled articles read only by headline
Company websites	Reseller page, new language, new location	Export, sales agents, localisation	Date added isn’t always known

Closed spaces stay out of reach for everyone: private Slack and Discord servers, private Facebook groups, direct messages. Part of the buying journey happens there, and that’s normal: it’s what’s known as the dark funnel. No public source sees the whole of it.

Does the opener change depending on the source?

The rule doesn’t change: talk about the prospect’s problem, not the signal. But how you reference it depends on the source. A customer review is public and concerns the business, not the person you’re contacting: you can refer to it, with tact.

Illustrative example

Signal: a hotel gets several Google reviews from guests who never heard back about an item left behind in their room.

Opener that falls flat: “Hi, I saw your hotel had bad reviews about lost property. Our software fixes that. Would you like a demo?”

Opener that gets a reply: “Going through your latest guest reviews, I noticed someone was still waiting to hear about a bracelet left in their room. It’s often the thing that falls through the cracks between reception and housekeeping. How does it usually go at your place when a guest calls about something left behind?”

The first version accuses and sells. The second shows you understand where the problem gets lost, and asks a question the manager wants to settle. To move from a reply to a meeting, the method is the same whatever the source: see from buying signal to meeting.

Should you monitor every source?

No. More sources means more noise, and a badly qualified signal costs more than no signal at all. Start with LinkedIn if your decision-makers are there. Add another source only if it carries a signal LinkedIn doesn’t give you, for a target LinkedIn reaches poorly.

That’s the split MeetMagnet itself follows: LinkedIn signals are included in every plan, and other sources (reviews, forums, social networks, job postings, press, the web) are wired in case by case as part of the multi-source option of the Assisted plan, because each one needs its own tuning for your target.
