B2B buying intent: you won’t find it on LinkedIn

LinkedIn’s Buyer Intent, the feature meant to reveal who’s about to buy, measures reactions to posts, profile views, and company page follows. In other words, attention paid to LinkedIn, never the act of buying itself.

Buying intent doesn’t live on LinkedIn: at best, it casts a shadow there. The real signal shows up in the public traces a purchase leaves behind: a tender, an authorization, a new company registration, a certification about to expire. BOAMP (France’s official public procurement bulletin) alone publishes nearly 200,000 of them a year. And at any given moment, barely 5% of B2B buyers are actually in market, according to the Ehrenberg-Bass Institute.

This article shows why LinkedIn captures activity but not decisions, what its Buyer Intent actually measures, where buying intent really becomes visible, and how to detect it without spending your days on it.

Why can’t you read buying intent on LinkedIn?

LinkedIn reads presence, not decisions. The platform knows who exists, who changed jobs, who reacted to a post. It has no idea that an organization just approved a budget, published a tender, or saw its certification come up for renewal. B2B purchases are decided in committees, budgets, and official registers, not in a news feed. What LinkedIn shows you is the professional; what a sales rep is looking for is the moment to buy.

The gap comes down to one fundamental fact. At any given moment, only 5% of B2B buyers are in market, versus 95% who aren’t, a ratio Professor John Dawes of the Ehrenberg-Bass Institute formalized as the 95:5 rule. A “like,” a comment, or a job change tells you someone is active on LinkedIn. It doesn’t tell you they’re part of the 5% making a decision right now.

LinkedIn is still valuable for what it does well: establishing an identity, a career history, and a way to reach the right person. It’s a living directory, not an intent detector. Confusing the two is like mistaking a business card for a purchase order.

What does LinkedIn’s Buyer Intent really measure?

Sales Navigator’s Buyer Intent aggregates more than 180 signals, all of the same kind: engagement with LinkedIn and with your website. Reactions and comments on your posts, views of your profile, new connections, follows of your page, accepted or declined InMails, ad interactions, and visits to your site when the Insight Tag is installed. None of these signals is the act of buying. They’re proxies for attention: useful, but indirect.

LinkedIn’s own documentation is unambiguous: the score combines activity on LinkedIn.com and website visits, not purchase events. A profile view doesn’t tell you why someone is looking at you: curiosity, competitive research, or recruiting. A page follow signals awareness, not a dated need.

The result is a signal centered on you rather than on the buyer. You learn who’s interested in your company on the platform. You don’t learn that a buyer just opened a contract for exactly your category, somewhere else, on a source LinkedIn doesn’t read. That’s the structural limit of what Sales Navigator’s Buyer Intent captures, and what it leaves in its blind spot.

Where does B2B buying intent really live?

Buying intent lives in the public traces the purchase itself produces. A tender on BOAMP, an equipment authorization, a new company registered with the INPI (France’s national business register and patent office), a proceeding published in the BODACC (France’s official bulletin of company announcements), a certification about to expire: each one is a documented, dated act that tells you a decision is underway. These sources are open and massive: nearly 200,000 public contracts a year on BOAMP alone, within a public procurement market worth €233 billion in 2024. None of them appears in a LinkedIn feed.

That’s where the 5% of buyers who are actually in market show themselves. A tender isn’t a hint of intent; it’s intent made public, with its category and its timeline. Where LinkedIn shows you continuous, ambiguous activity, these registers give you a clear event.

These signals aren’t read in isolation: it’s cross-referencing them on the same organization that turns a weak hint into a dated buying window. The logic varies by trade. An accounting firm, for example, reads new company registrations in the INPI and BODACC registers as a signal of a new client, where LinkedIn shows nothing. A plumbing and heating contractor reads public works contracts and building permits as a signal of an upcoming project. More broadly, construction companies spot their projects in BOAMP and building permits before the tender. A law firm, for its part, reads general counsel hires and appointments as a signal of upcoming advisory needs, rather than waiting for a LinkedIn profile to confirm it. Translating your product portfolio into concrete public signals to monitor is what we scope in 30 minutes during a prospecting scoping call.

How do you detect these signals without spending your days on it?

Detection comes down to a single capability: continuously cross-referencing public sources that nobody connects by hand. An agent scans tenders, legal registers, authorizations, and publications, matches each event to the right decision-maker, and surfaces only the prospects carrying an active signal. The sales rep gets a dated, contextualized file, not a cold list. That’s how Agify works.

The contrast with volume is stark. A French MedTech specializing in medical imaging applied this cross-referencing across eight European countries: a large base of radiologists drawn from more than ten public sources, filtered in six weeks down to only the qualified prospects. Meeting prep went from 30 to 45 minutes of research to a few minutes. None of these prospects came out of a LinkedIn filter alone. That gain is also better measured in redeployed sales budget than in lead count: it wasn’t the contact counter that moved, it was the time given back to selling.

It’s the exact opposite of the mass-sending AI SDR that fails by speeding up the wrong move: here, automation applies to reading signals, never to sending. The full approach, from detected signal to contextual message, is laid out in reverse prospecting with public buying signals. Once that signal is detected, what separates a message built on it from a simple merge field makes all the difference in reply rate.

Frequently asked questions

Is LinkedIn useless for B2B prospecting?

No. LinkedIn remains one of the best tools for identifying a person, checking their background, and reaching them. Its limit lies elsewhere: it captures activity on the platform, not the purchase decision that gets made in a committee or published in a register. Use it to find out who exists and how to contact them, not to find out when a need arises.

What is a public buying signal?

It’s an event made public by the buyer itself that reveals a decision in progress: a tender on BOAMP, an equipment authorization, a new company registration, a certification about to expire. Unlike a “like” or a profile view, it’s dated, documented, and tied to a specific purchasing category.

Isn’t Sales Navigator’s Buyer Intent enough?

It identifies who interacts with you on LinkedIn and on your site, which is useful but partial. Its score aggregates engagement signals (reactions, views, InMails, site visits), not purchase acts like a public contract or a BODACC proceeding. It’s therefore blind to most real traces of intent, which live outside the platform.

Is it legal to use this public data?

Yes. BOAMP, the INPI, the BODACC, ARS authorizations, and certifications are official, open sources published to be consulted. Cross-referencing them to prioritize prospecting stays within the GDPR framework as long as you’re processing public professional data and respecting people’s rights.

How long does a buying signal stay actionable?

Its useful life is short, on the order of 7 to 21 days depending on the type of signal. A tender has a deadline; a recent appointment opens a brief window. Hence the need for continuous monitoring: a signal spotted six months too late is a dead signal.

Conclusion

LinkedIn is a directory, not an intent detector. Three takeaways. The platform measures activity and presence, while purchases are decided elsewhere and published in official registers. The real signal is a dated act (a tender, an authorization, a new company, a certification deadline), not a reaction to a post. And since only 5% of buyers are in market at any given moment, everything comes down to spotting those acts where they appear, when they appear.

What’s left is figuring out which public sources announce your buyers in your specific market. Let’s spend 30 minutes together on how to translate your offer into signals to monitor.
