B2B Buying Signals: 40 Examples by Industry and How to Use Them

Most signal feeds fail for the same reason: they mix real events with trivia. Before an event goes on your list, it should pass three tests.

1. You can verify it. There is a press release, a job post, a filing, a tender notice or a post with a date. If you cannot link to it, you cannot mention it, and it is probably a guess.
2. It connects to what you sell. "They raised a Series B" is interesting. "They raised a Series B to open two fulfilment centres" is a signal if you sell to fulfilment centres.
3. It starts a clock. The event forces a decision within a window you can name: before go-live, before the certificate expires, within a new executive's first quarter.

Events that fail the tests can still be useful for ranking accounts. They just are not a reason to write to anyone today. Once a signal passes, the next step is turning it into a conversation, which we cover in the signal-based selling playbook.

Each table shows what the signal usually means, who tends to own the decision, how long the window typically stays open and how strong the signal is on its own. Windows and strength are rules of thumb. Your market will shift them, so treat the tables as a starting map.

Growth events create purchases that did not exist last month. A new site needs equipment, systems, people and services, and most of it gets bought before the doors open.

Job posts are public, dated and specific. They tell you what a company is about to build, and sometimes which tools it already uses.

Money on its own is a weak signal. Money with a stated purpose is a strong one, because the company has already told you what it plans to buy.

Compliance deadlines are the most predictable signals there are. The date is known in advance and the company cannot ignore it.

Technology signals tell you when an incumbent vendor is weakest. That is usually the only time a switch makes sense to the buyer.

Social signals are the fastest and the noisiest. Treat them as a reason to look closer, then confirm with something from the groups above.

The same event means different things to different sellers. A new distribution centre is a top signal for a WMS vendor and irrelevant for an HR software company. These are the signals that matter most in the industries we work with.

These four terms get used interchangeably. They are different tools, and mixing them up leads to bad outreach.

The short version: intent data and lead scoring help you rank, buying signals help you act. We compare the first two in depth in buying signals vs intent data, and look at one popular score specifically in why ZoomInfo's intent score is not enough.

When a feed produces more accounts than your team can work, rank them on three questions:

• How specific is it to you? An event that names your category beats one that only implies growth.
• How well does the account fit? A strong signal at a company outside your ICP is still a long shot.
• How fresh is it? Windows close. A two-week-old tender is worth more than a four-month-old funding round.

Stacked signals deserve the top of the list. A warehouse announcement on its own is good. The same announcement followed by a job post for a WMS administrator and a LinkedIn post from the site director about hiring is a company in the middle of a buying decision. Two medium signals that point the same way often beat one strong signal on its own.

Also watch for negative signals: a competitor just signed a multi-year contract, a hiring freeze, layoffs, or an acquisition that moves decisions to a parent company abroad. These belong in the same feed, because they save your team from chasing dead accounts.

Most signal advice is written for the US market. Three things work differently in Europe.

• Language. Many of the best signals are published in German, French, Dutch, Italian, Polish or Finnish, on local news sites and regional business registers that English-only tools miss.
• Public procurement. EU tenders are published on TED and national portals. They are some of the clearest signals available because budget, specs and deadlines are all public.
• Data protection. Company events are generally not personal data, but the people you contact are. GDPR and national e-marketing rules shape how you reach out. We cover this in GDPR and signal-based prospecting in the EU.

For one narrow niche, a person with an hour a day can cover a lot by hand:

• News alerts for facility openings, expansions and acquisitions in your target regions
• Job boards filtered for the roles that reveal a new function or a new system
• Tender portals such as TED for public procurement
• Certificate registries and supplier directories for expiry dates
• LinkedIn, Reddit and X for requests and complaints. Our LinkedIn buying intent signals and Reddit monitoring workflow show how

It stops scaling once you cover several countries, languages and signal types. Then the work is less about finding events and more about filtering them: checking fit, removing disqualified accounts and finding the right person.

That is what Karhuno does. You describe your ICP and the events that matter to you, and Karhuno monitors the web, LinkedIn, tenders and local news in European languages. Each opportunity arrives with the source link, account context, disqualifier checks and the decision makers to contact. Plans start at $299/month for 100 deal opportunities, with a 7-day free trial.
