A B2B prospect receives dozens of near-identical messages every week. Finding the right moment to write is no longer enough: others have seen the same signal as you. What makes the difference is what you write on the back of that signal.

This article lists 25 B2B buying signals, sorted into five groups. For each group, you will find the opener that falls flat and the one that gets a reply. Then the next step: how to get from the signal to a meeting.

What is a B2B buying signal, and why isn’t it enough?

A buying signal is a public trace showing that a company, or someone who makes decisions there, is entering a period where they may need what you sell. A new hire, an appointment, a funding round, a comment left under a post about their problem.

The signal answers one question only: when to write. It doesn’t tell you what to write, who exactly to write to, or how to get a meeting. And it has an obvious limit: a public signal is visible to all your competitors. The day an SME announces a funding round, it gets congratulation messages from ten suppliers, almost all identical.

That is why this guide pairs each group of signals with an opener. The signal opens a window. The opener decides whether the person replies.

What are the two main types of buying signals?

Not all signals read the same way. There are two kinds, and they are not written the same way in a message.

Interactions Moments
What it is The person reacts to content on your topic: a like, a comment, a question, a webinar sign-up The person or their company announces a fact: a hire, a new role, a new site, an acquisition
What it tells you This topic is on their mind right now Their situation is changing, a need may appear
Strength Weak on its own, stronger if repeated on the same theme Often strong, if the fact is linked to your offer
How to write it Talk about the topic, never the like Build on the fact, briefly
Where to see it Mostly LinkedIn, where reactions are public LinkedIn, job postings, press, company websites

Interactions are often called weak signals. They are more discreet, so your competitors use them less. Moments are more visible, so they are more contested. Both have their place, as long as you don’t treat them as a list of names to contact.

Which 25 B2B buying signals should you watch?

The examples below are described in plain language, as you would read them on a prospect record. For each signal, the question is the same: does this fact create a need that my offer solves?

Group 1: interactions on your topic

  1. Reacts to posts about the problem you solve. A regional director running several sites likes a post about the pressure business leaders are under. Weak if it’s a one-off, stronger if it keeps happening on the same theme.
  2. Comments with a question. An industrial purchasing manager asks, under a sector post, how other plants handle delays from their subcontractors. A comment commits more than a like, a question even more so.
  3. Reacts on a competitor’s or market player’s post. The finance director of an SME comments on a software vendor’s post about the e-invoicing reform. Strong if the person has the right job title, discard otherwise.
  4. Attends a webinar or event on the topic. A branch director reacts to the announcement of a webinar on remote management, or says she is attending.
  5. Posts about a difficulty they are facing. An SME founder writes that he has been carrying every decision alone since the company grew. This is the strongest interaction: the person has put the problem into words themselves.

Illustrative example. Signal: the finance director of an industrial SME comments on a software vendor’s post about e-invoicing.

Opener that falls flat: “Hi, I saw your comment on X’s post. We provide an e-invoicing solution. Do you have 15 minutes this week?”

Opener that gets a reply: “In industrial SMEs, the longest part of moving to e-invoicing often isn’t the tool, it’s cleaning up the supplier records. Where are you with that?”

The flat version quotes the comment, which feels like being watched, then asks for a slot from someone who doesn’t know you. The second one talks about the topic from the ground and asks a question that can be answered in one sentence.

Group 2: hiring

  1. Hires for a role linked to your offer. A manufacturer hires a buyer to structure its subcontractor panel. The need is written in the ad.
  2. Hires its first salesperson. A 15-person software company is looking for its first field salesperson, when the founder used to sell alone. Sales becomes a leadership topic.
  3. Opens a first export role. An SME hires its first export manager for Germany. Everything international is about to be bought for the first time.
  4. Creates a new role. A food group creates a head of CSR role and mentions its first carbon footprint assessment in the duties. A new role signals a project, not a replacement.
  5. Reposts the same role. The sales director role is back online for the third time in a year. A weaker signal, but useful for a recruitment firm or an outsourcing offer.

Illustrative example. Signal: a 60-person industrial SME is hiring its first export manager.

Opener that falls flat: “Congratulations on your international growth! We support companies with their export strategy. Would you be open to a chat?”

Opener that gets a reply: “You’re hiring your first export manager. In the first few months, the hardest part for them will often be getting real conversations with distributors, not a list of names. Are you planning to prepare the ground for them, or let them build their own network?”

Hiring is covered in detail in our article on job postings as a buying signal.

Group 3: people changes

  1. A new decision-maker starts. A new operations director has just taken charge of production at a site. Newcomers often review their suppliers, especially in their first months.
  2. A new head of purchasing arrives. They build their panel, meet the incumbent suppliers and look at the alternatives.
  3. A manager is promoted to a key role. They know the company, but inherit a new budget and new objectives.
  4. A long-standing leader leaves. The partnerships they carried personally are no longer a given. That is true for you if you are the challenger, and for you too if you are the incumbent supplier.

A work anniversary, on the other hand, is a weak signal: LinkedIn highlights it, but nothing changes in the person’s situation.

Illustrative example. Signal: a production director started at a mid-sized engineering company six weeks ago.

Opener that falls flat: “Congratulations on your new role! Allow me to introduce our company, industrial maintenance specialists for 20 years.”

Opener that gets a reply: “Six weeks into a production role, you’ve usually walked every line and already know which ones cause trouble. Is maintenance one of the things you want to take in hand, or is it more the planning?”

This signal has its own article: a job change as a buying signal.

Group 4: money and structure

  1. Raises funding. A start-up announces a round to hire and open a new country. It will buy fast, but it is also heavily solicited.
  2. Acquires or merges. A family-owned group buys a regional competitor. Tools, payroll, contracts and suppliers will all need aligning.
  3. Wins public funding or a grant. A funded innovation project has to be delivered, often with outside providers.
  4. Wins a large contract or tender. A haulier wins a multi-year contract with a national retailer: it needs lorries, drivers, maybe a warehouse.
  5. Opens a site or a plant. A mid-sized company opens a new production workshop. Energy, maintenance, safety, recruitment, catering: a whole panel of suppliers opens up.

Illustrative example. Signal: a services SME announces a funding round to double its headcount in two years.

Opener that falls flat: “Well done on your funding round! It’s the perfect time to structure your growth. Our solution can help.”

Opener that gets a reply: “Doubling the team in two years means bringing in a lot of managers, and often employee benefits questions you didn’t have at twenty people. Is that already sorted on your side, or still on the pile?”

The flat version could be sent to any company that raises money. The second one draws a concrete consequence from the announcement, specific to the sender’s trade (here, a group benefits broker).

Group 5: projects, tools and deadlines

  1. Enters a new market. A cosmetics SME adds German and Spanish versions of its website. Translation, logistics, export advice, tax.
  2. Looks for resellers. A furniture manufacturer publishes a “Become a reseller” page. Useful for independent sales agents and logistics providers.
  3. Calls for suppliers. A mid-sized company publishes a supplier registration page for a purchasing category. That is an explicit request.
  4. Prepares a tool change. A mid-sized company hires an ERP project manager on an 18-month fixed-term contract, with “migration” in the job title. Integrators, IT consulting, change management.
  5. Faces a regulatory deadline. E-invoicing reform, sustainability reporting obligations, security standards: the date is imposed on the company, and so is the need.
  6. Suffers a public incident. An SME explains in the local press that a cyberattack stopped its production. A strong signal, to be handled with tact.

Illustrative example. Signal: a garden furniture manufacturer publishes a “Become a reseller” page and is looking for outlets in the west of the country.

Opener that falls flat: “Hi, I’m an independent sales agent looking for new brands to represent. Please find my brochure attached.”

Opener that gets a reply: “You’re looking for resellers in the west. The garden centres I visit every week are asking for exactly this kind of range. Are you after direct outlets, or someone to look after them on the ground?”

Which signals should you ignore?

A list of 25 signals makes it feel like everything is an opportunity. It isn’t. Many signals are just noise, and reaching out on noise wears down your reputation faster than a generic message.

  1. Reactions from your peers. At an industrial subcontractor we work with, posts from workshops showing off their new machines are mostly liked by other workshops, in other words competitors. A signal only counts if the person’s role and company match a real buyer.
  2. Likes on corporate posts. Liking a company’s anniversary post says nothing about a need.
  3. Signals you can’t date. A job posting that has already been filled, a web page with no known publication date: the signal becomes false, and so does your message.
  4. Signals unrelated to your offer. A funding round is an excellent signal for a recruitment firm, and an ordinary one for an accounting software vendor.
  5. Work anniversaries. Highlighted by LinkedIn, rarely linked to any real change.

The sorting method is detailed in buying signal or noise: how to qualify a signal.

How do you write the opener from the signal?

The examples above all follow the same rules. They are simple, but easy to forget when you write fast.

  1. For an interaction, talk about the topic, never the action. “I saw you liked this post” makes people uncomfortable. Pick up the idea that made them react.
  2. For a published fact, mention it in half a sentence. “You’re hiring an industrial buyer” is enough. No three-line congratulations.
  3. Draw a concrete consequence, from your own experience. What you see at your clients in the same situation, not what your product does.
  4. End with a question about their situation. One that can be answered in a sentence, not a request for a slot from someone who doesn’t know you yet.
  5. Keep it short. Three or four sentences. The pitch comes once the person has replied.

Here is a real case, anonymised, from an executive coach prospecting on LinkedIn.

Real case, anonymised. Signal: a regional director running several sites in a national group liked a post about stress among business leaders.

Opener that falls flat (what could have been written): “Your like on this post encouraged me to get in touch. I’m an executive coach. Would you have time for a discovery call?”

Opener that got a reply: “Pressure is part of your role as a multi-site leader. But it shouldn’t be treated as normal. I help leaders protect their balance. Would you like to talk about your current priorities?”

The prospect replied the same day, picking up the line about pressure that “shouldn’t be treated as normal”, and a video meeting was booked. It was that sentence, built on the topic of the signal, that triggered the reply. Not the like.

How do you get from signal to meeting?

The signal is only the start. Between a like and a meeting there are several steps, and that is often where signal-based prospecting stops.

  1. Check the target. Do the role and the company match a buyer? If not, move on, even if the signal is strong.
  2. Date the signal. A signal that is several months old no longer justifies the same message.
  3. Write the opener. Following the rules above, and reviewed by someone who knows the client’s trade.
  4. Choose the channel. LinkedIn when the signal comes from LinkedIn, email when you have a reliable address and a topic that needs a bit more room.
  5. Follow up with a new angle. A follow-up that says “just circling back” adds nothing. A follow-up that brings an idea or an example does.
  6. Suggest the meeting once the conversation is under way. When the person has replied on substance, a slot feels natural. Before that, it scares them off.

Each step is detailed in from buying signal to meeting: the 4-step method.

Do you need a tool to track these signals?

For ten target accounts, manual monitoring is enough: alerts on a few companies, regular reading of LinkedIn and the local press. Beyond that, the time spent searching quickly outgrows the time spent writing. And it is the writing that gets the reply.

Option What you get Observed price (September 2026) Who writes the opener
Manual monitoring A few well-chosen signals Your time You
Prospecting software on its own Signals and lists, in volume €89 to €300/month You, or a generic template
Prospecting agency Meetings, often by phone €1,000 to €3,000/month The agency
Managed service Sorted signals and reviewed openers Varies by offer The tool and a person, approved by you

Support makes a real difference. With the same signal, what changes is how the target is calibrated and how the messages are reviewed.

That is the approach MeetMagnet takes with its signal-based prospecting AI: spot, every day, the LinkedIn interactions and posts linked to your offer, write an opener from each signal, then send it by LinkedIn or email, with a person who calibrates and follows the account. Other sources (job postings, press, reviews, forums) can be added with the multi-source option of the Assisted plan. You can browse the signals that can be spotted by source, and in particular what can be seen on LinkedIn.

Frequently asked questions

What is the most reliable B2B buying signal?

There isn't just one. The strongest are the ones that commit the company: a hire for a role linked to your offer, a decision-maker who has just started, a new site. How reliable they are depends mostly on how closely they relate to what you sell and how fresh they are. You must be able to date the signal.

Should I mention the signal in the first message?

For a published fact (a hire, an appointment), yes, briefly, in half a sentence. For an interaction (a like, a comment), no: writing “I saw you liked this post” makes people uncomfortable. Talk about the topic that caught their attention instead, as if you were discussing it with them.

How long does a buying signal stay usable?

It depends on the signal. An interaction on a topic is useful as long as the topic is still live for that person. A new role is mostly worth working in the first few months. A job posting is only usable while it is online. In every case, date the signal and check it before you write.

Do buying signals replace classic targeting by industry and company size?

No, they add to it. Targeting tells you who you can sell to; the signal tells you when to write. A strong signal at a company outside your target is still a poor prospect. Define your target first, then look for the signals that, at those companies, point to a need linked to your offer.
