Buying Signals: The Complete Taxonomy
B2B buying signals fall into four families: trigger events, behavioural signals, technographic signals, and relationship signals. Trigger events are the strongest predictors because they create the problem you solve. Every signal has a decay window, and acting outside it is close to acting on no signal at all.
- Trigger events beat behaviour. Something changed at the company outranks someone read something.
- Every signal has a decay window. A 30-day-old hiring signal is a different signal from a 3-day-old one.
- Combined signals are worth far more than the sum — two weak signals together often beat one strong one.
- Weight signals by observed conversion in your own data, not by how compelling they feel.
- Track a maximum of eight to ten signals. Beyond that nobody can reason about the score.
The four families
Signals are frequently discussed as one undifferentiated pool, which makes them impossible to weight sensibly. They divide cleanly into four families with different strengths and very different decay behaviour.
| Family | What it is | Strength | Typical decay |
|---|---|---|---|
| Trigger events | Something changed at the company | Strongest | 30–90 days |
| Behavioural | Someone did something observable | Strong but noisy | 3–14 days |
| Technographic | What they run, and what changed | Moderate | 60–180 days |
| Relationship | A person you know moved or connected | Strong, low volume | 60–120 days |
Trigger events: the strongest family
Trigger events outrank everything else for a structural reason: they do not indicate interest, they create the problem you solve. A company that just opened a second office has a genuinely new problem regardless of whether anyone there has thought about vendors.
| Signal | Predicts | Decay |
|---|---|---|
| Hiring for roles you serve | A function being built or rebuilt right now | 60–90 days |
| Funding round | Budget and a mandate to spend it | 90–180 days |
| Leadership change in your buyer's function | New priorities and a willingness to change vendors | 60–120 days |
| Expansion — office, market, product | Operational strain in what you fix | 60–90 days |
| M&A activity | Systems consolidation, often urgent | 120–180 days |
| Regulatory change in their sector | A compliance deadline they cannot ignore | Until the deadline |
Behavioural signals
Strong but noisy, and they decay fastest of any family. A pricing page visit is meaningful for about three days and close to meaningless after two weeks.
- Pricing page visit — the strongest single behavioural signal in B2B, and the one most often left uninstrumented.
- Repeat sessions from the same company within a short window — more predictive than any single deep session.
- Documentation or integration page reads — indicates technical evaluation, which usually means a real project.
- Comparison or competitor page views — active evaluation, and the shortest window of all.
- Multiple people from one domain in the same week — the buying group is forming, which is a much stronger signal than one person returning repeatedly.
The last one is worth building for specifically. One person visiting five times is interest; five people visiting once each is a committee, and committees buy.
Technographic and relationship signals
Technographic signals are moderate in strength and slow to decay, which makes them better suited to segmentation than to timing. What matters more than the current stack is a change in it — a tool added or removed indicates an active project in a way a static install does not.
Relationship signals are low-volume and disproportionately strong. A champion from a closed-won account moving to a new company is arguably the single highest-converting signal available in B2B, and it costs almost nothing to monitor if you track your own historical contacts.
Combination is where the value is
Individual signals are weak predictors. Combinations are not, and the effect is multiplicative rather than additive.
| Combination | Interpretation | Relative strength |
|---|---|---|
| Hiring + pricing page visit | Building the function and actively evaluating | Very high |
| Funding + leadership change | New budget and a new person who wants to spend it | Very high |
| Competitor tool removed + docs read | Mid-replacement, technical evaluation live | Very high |
| Three people from one domain in a week | Buying committee has formed | High |
| Topic intent alone | Someone somewhere read something | Low |
The last row is the honest assessment of third-party topic data used in isolation, and the reason it disappoints so often — see intent data for the fuller argument.
Weighting signals honestly
- 01Start with equal weights and observe
Do not guess the weights. Run every signal at equal weight for a quarter and record which ones preceded real opportunities in your own data.
- 02Weight by observed conversion, not intuition
Signals that feel compelling frequently underperform. Funding rounds feel strong and often convert poorly because everyone in the market contacts the same company that week.
- 03Apply a decay function, not a binary flag
A signal three days old and one thirty days old should not carry the same weight. Linear decay to the window's end is usually good enough and far better than a flag.
- 04Cap the number you track
Eight to ten maximum. Beyond that nobody can explain why an account scored what it did, and a score nobody can explain is a score sales will ignore.
Turning a signal into an action
A signal that does not produce a contact attempt inside its decay window is an expensive way of generating a report. The operational requirement is speed rather than sophistication: detect, filter for fit, suppress, enrich, route, and contact — ideally within 48 hours for behavioural signals and within a fortnight for trigger events.
The metric that captures this is signal-to-action latency, and it is the number most worth tracking in a signal-driven motion. The pipeline that delivers it is described in the GTM tech stack, and the message it should produce in personalised outreach at scale.
