LinkedIn Buying Signals: 12 Worth Chasing, Sorted by Where You See Them

LinkedIn buying signals are public actions that show a person or company is closer to buying than a cold list would suggest: a post describing the problem you solve, a question under a competitor's post, a new role that owns your category, a job ad for the person who would use your product. Twelve are worth a message. This page sorts them by where you see them: a free account shows some, Sales Navigator shows others, and a few only appear if someone is watching other people's posts.

What are LinkedIn buying signals?

A buying signal is an action a prospect takes before a purchase that you can observe from the outside. On LinkedIn the observable actions are posts, comments, reactions, follows, profile changes, job ads and company announcements. The definition, and a three-question test for whether something counts, is in the buying signal lesson; this page is about the LinkedIn ones specifically.

Two things make LinkedIn different from other signal sources. First, most of the signals name a person, not a company, so you know who to write to without a second lookup. Second, almost all of them are visible to anyone logged in, so the question is rarely "can I see this" and usually "will I be looking at the right time". That second question is what decides whether you chase signals by hand or let software watch.

Which LinkedIn buying signals are worth chasing?

Here are the twelve, sorted by where you see them. Strength is out of five and assumes the person fits your ideal customer profile; a signal from someone who does not fit is worth nothing. The last column is the window in which a message still reads as timely.

The pattern in the table is the point. The strongest signals are things people say in public, and a free account shows every one of them. Sales Navigator adds searchability and a narrow set of interest-in-you signals. The competitor signals are the hardest to catch because nobody is notified when a stranger reacts to someone else's post.

What can you see with a free LinkedIn account?

More than most tool pages admit. Signals 1 to 9 need nothing but a logged-in account and a routine.

Posts search (signals 1, 2 and 3). Type the phrase a buyer would use into the search bar, switch to the Posts tab, and sort by Latest. Search what a buyer says, not what you sell: "anyone using" plus your category, "looking for a tool", "switching from", the name of the tool you replace plus "frustrated". Use quotation marks around the phrase. The LinkedIn lead generation guide has the full Boolean strings for the Posts and People tabs if you want to copy them rather than build your own.

The post itself (signal 4). Under any public post, the comments are on the page and the reaction count opens the full list of names with headlines. A comment that asks a question or raises an objection is the single best person-level signal you can get for free, because the person has told you the topic, their stance and their timing in one place.

The profile (signal 5). A new title and a new company show on the profile and usually as a "started a new position" post in the feed. On a free account you find these by chance or by checking saved profiles. In Sales Navigator they become a filter, covered below.

The company page (signals 6 and 7). The Jobs tab on a competitor's or prospect's company page lists what they are hiring for. A company hiring its first SDR, its first RevOps hire, or a head of the function your product serves is budgeting for the problem. The Posts tab on the same page carries funding and expansion announcements before any database has them.

The hashtag feed (signal 8). Follow the two or three hashtags your buyers use and read the feed twice a week. One post under a hashtag is noise. The same person three times in a month is a topic owner.

Your notifications (signal 9). Anyone who comments on your posts, reacts repeatedly or follows your page is raising a hand. These are the easiest signals to catch and the most often ignored, because they arrive mixed with birthday reminders.

The cost of the free route is attention, not money. Each of these is a place you must visit, and a post you see on Friday that was published on Tuesday is three days cold. The signal-based outbound guide turns these into a daily routine with a signal log, if you want to run it by hand.

What does Sales Navigator add?

Two things, and it is worth being precise because the ranking pages are vague here.

First, Spotlights. LinkedIn's own Sales Navigator how-to page describes a Job Changes filter inside the Spotlights section that finds connections who recently changed jobs, says decision-makers are "62% more receptive to outreach once they've made that move", and describes alerts when saved leads "make a move, like changing jobs". That turns signal 5 from something you stumble on into something you can search and be told about. Vendor walkthroughs such as ColdIQ's list the account-side paths they use as well, including Spotlight filters for funding events and senior leadership changes and a Job opportunities filter for companies hiring on LinkedIn; check the exact filter names in your own account before you build a routine on them.

Second, Buyer Intent, which is signal 10 and is narrower than its name. LinkedIn's guide to Buyer Intent lists what feeds it: following a company, company page visits, profile visits to sellers on contract or to leadership, new connections to your team, lead-form completion through an ad, ads engagement, accepting an InMail, and visits to the company's official website. Every item on that list is interest in you. Nothing on it is engagement with another company's posts. Buyer Intent tells you who is warming up to your company; it cannot tell you who is warming up to a competitor.

So the honest summary of Sales Navigator for signal work: it is the best way to catch job changes and to see who is quietly looking at you, and it does nothing for the competitor and topic signals that make up most of the table.

Which signals can only a watcher see?

Signals 11 and 12 are the competitor signals, and they have a structural problem: LinkedIn notifies the author of a post about engagement, not you. Reactions and comments on a competitor's post are public, but you only see them if you open that post, and you only open it if you knew it existed.

By hand, that means a list of the competitor profiles and industry leaders who post most, a visit to each one's Activity tab twice a week, and the reaction list under every relevant post copied into a sheet. The guide to tracking competitor post engagers gives the click path, a volume rule for when clicking stops being enough, and what LinkedIn's own API and analytics will not give you.

The reason signal 12 is strong and signal 11 is weak is the same reason this is hard to do by hand. One reaction is curiosity. The same person reacting to two competitors in a month, or commenting under one and following another, is comparing. Seeing that pattern means remembering every name across every post, which a sheet does badly and a person does worse. This is the step where software earns its place: Intentsly's LinkedIn signals watch the competitor and leader profiles you name, capture each person who likes, comments or shares, and score them against your ICP so the repeat engagers surface on their own instead of waiting for you to notice.

How do you score LinkedIn buying signals before messaging?

Most names a signal produces are peers, the competitor's own staff, recruiters and people who react to everything. Score before you write. Copy this into your sheet and change the role line to match your customer profile.

Then apply a decay rule, because a signal is a timestamp, not a trait. Halve the points of any post, comment or reaction signal after 7 days and drop it after 30. Job changes and hiring keep full points for 30 days and drop after 90. Funding keeps full points for 30 days and is context only after that.

Message anything at 7 or above this week. Keep 4 to 6 in a second column and move them up when a second signal arrives. Below 4, leave the person alone; a single reaction from someone with the right title is still a single reaction.

The score also decides what you send. A 7 from a public question gets a message that answers the question. A 7 built from a job change plus a hiring post gets a connection note about the role, with no mention of the hiring post. The signal picks the opener, the score picks whether to send.

Which LinkedIn buying signals are not worth a message?

Several things that show up in every tool's notification feed are not signals, and messaging them costs trust you need later.

• A profile view with nothing else around it. People look at profiles when they are hiring, job hunting, checking a name from an email, or bored. Treat it as context for a signal that arrives later, not as an opener.
• An accepted connection request. Acceptance is a reflex for many people. It is permission to write, not a reason to.
• A single reaction to a post that went viral outside your topic. A post about a founder's burnout gets reactions from people who have nothing to do with the category; the topic of the post decides whether the reaction means anything.
• Work anniversaries, birthdays and "proud to share" certificate posts. These generate the most suggested messages on LinkedIn and the least pipeline.
• Engagement from the competitor's own employees, from agencies that sell the competitor, and from people who sell to the same buyers you do. They are the loudest voices under a competitor's post and the worst leads in it.

The message templates for buying signals has a longer list of what not to message, and one complete sequence for each signal that is worth it.

How fast should you respond to a LinkedIn buying signal?

The windows in the first table are not research findings; nobody has measured them across enough teams to call them constants, and Tapistro's tiered guide is candid that its own windows are "operating defaults rather than measured constants". They are the windows in which a reference to the signal still reads as natural rather than as surveillance.

A rule that holds across the table: respond to things people said within three days, and to things that happened to them within thirty. A question under a post is cold in a week. A new role is still fresh a month later, because the person is still forming opinions about tools and is expected to be approached.

Speed is the second reason software beats a routine. The by-hand method sees a Tuesday post on Friday. A watcher sees it Tuesday. For the competitor signals, where the window is days and the engager list is long, that gap is most of the value.

What to say is shorter than most guides make it. Reference the topic, never the act of watching. "Your question about onboarding time under that thread" is fine; "I saw you liked a competitor's post" is not. Offer one useful thing related to the topic, and ask a question that is easy to answer. The templates page above has the exact wording per signal, with character counts.

What we measured when we ran this on ourselves

We launched Intentsly into a market full of outreach tools with bigger budgets and better-known names, so we pointed our own LinkedIn signals and AI SDR at founders who were posting about cold outreach burnout, which is signals 2 and 3 in the table above. The conversational AI handled the replies and booked the meetings. The result was 14 qualified demos in 14 days with zero manual outreach, at a reply rate 4x our previous cold campaigns, and most of those leads came from signals caught in real time rather than from any list. The full account is in our case study.

Across Intentsly customers in October 2026, each signal agent finds around 1,000 leads a month and a typical account books 2 to 4 meetings a week. Those are averages across different markets and offers, not a promise. The honest limits sit alongside them: Intentsly reads LinkedIn only, sends LinkedIn messages and connection requests only, supports up to 2 sender accounts per plan, and caps each account at 30 messages and 30 connection requests a day, with 15 recommended.

The point of the numbers is not the tool. Signals 1 to 4 are free to read and produced the demos. The tool removed the three-day lag and the scoring spreadsheet, which is the part a two-person team cannot sustain by hand.

What to do this week

Open the Posts tab, search the phrase your last customer used before buying, and message the three best fits from the last seven days using the scoring table. That alone will show you whether signal-based outreach works for your offer. If you would rather see the scored list than build it, try the AI with your competitors' profiles: it shows matching buyers with no account. And if you want our own list of 12 buying signals worth chasing and 8 to ignore, with a script for each, the Buying Signal Playbook is free.

FAQ

What are buying signals on LinkedIn?

They are public actions that show a person or company is closer to buying than their title alone suggests: a post asking for recommendations, a complaint about a tool, a question under a competitor's post, a new role that owns your category, a job ad for the person who would use your product. They differ from intent data, which is usually aggregated at company level and bought from a third party; the intent data lesson covers that split.

Is a LinkedIn like a buying signal?

On its own, barely. A single reaction tells you the person saw the post and did not disagree. It becomes a signal when it repeats, when it sits under a post about your exact topic, or when it arrives alongside something else, like a recent job change or a hiring post from their company. Score a lone like at 1 and wait for the second signal before you write.

Does Sales Navigator show buying signals?

Partly. Its Job Changes spotlight and alerts on saved leads catch role changes well, and Buyer Intent shows interest in your own company: page visits, profile visits to your team, ad engagement and website visits, per LinkedIn's own description. It does not show who is engaging with competitor posts or asking for recommendations in public, which are the strongest person-level signals on the platform.

How fast should you respond to a buying signal on LinkedIn?

Within three days for anything the person said in public, and the same day for a direct question or a request for recommendations. Within thirty days for things that happened to them, such as a new role or a funding round. After those windows, the signal is still useful as context for scoring, but referencing it in a message starts to read as surveillance.

How many signals do you need before reaching out?

One strong signal from a person who fits your customer profile is enough: a public request for alternatives, a complaint about the tool you replace, a question under a competitor's post. Weak signals need company. A reaction, a profile view or a company follow should wait for a second signal within thirty days before anyone writes to that person.

Is it allowed to track buying signals on LinkedIn?

Reading public posts, comments and reaction lists by hand is normal use of the platform. LinkedIn's user agreement bars scraping and unapproved automation, and a browser extension that scrolls lists inside your own session puts your account at that risk. Tools that read public pages without your login keep your account out of it. Whatever you use, send from a real profile and stay inside the daily limits.
