Buying Signal
A buying signal is an observable data point suggesting a company or individual has entered an active purchasing evaluation, such as a job change, funding announcement, or repeated engagement with specific content. It is not the same thing as generic social interaction.
What it actually is
A buying signal is any concrete, observable event that tells you a prospect or account is moving toward a purchase decision, not just noticing you exist. Firmographic changes like new funding, a leadership hire, or a headcount jump in a relevant department all count. So does behavioral data: someone visiting your pricing page twice in a week, or a company showing up repeatedly in intent data around a category you sell into. On LinkedIn specifically, a company posting about growth or a new initiative is often a sign it's willing to fuel that growth with new spend, which makes it worth watching (coldIQ).
Why it matters
Selling on timing beats selling on persistence. Reps who chase every lead with the same cadence burn time on accounts that are nowhere near ready and miss the narrow windows where a prospect is actually receptive. Buying signals exist to help you triage: who gets a call today, who gets a nurture sequence, who gets ignored for another quarter. Intent platforms, firmographic changes, website behavior, and community activity like review site comparisons or engagement patterns on LinkedIn are the four broad buckets worth tracking (GrowLeads).
The misconception
The mistake is flattening every LinkedIn interaction into the same bucket. A like is not a buying signal. A comment on someone else's post is not a buying signal. These are visibility events, they tell you someone saw your content, not that they're evaluating a purchase. Treating a like the same as a repeat profile visit or a saved post inflates your pipeline with noise and trains your team to chase warmth that isn't there.
How it's actually measured
Real signals cluster around specificity and repetition. A single like means nothing. A prospect visiting your profile three times in two weeks, saving a post about a problem your product solves, or a target account showing up in intent data around your category are all signals worth acting on. Job changes into a buying-relevant role, and firmographic shifts like a funding round or new hire in the department that would own your solution, are stronger still because they change the account's actual need, not just its attention (GrowLeads, coldIQ). The discipline is in ranking signals by how directly they connect to purchase readiness, not in counting engagement as a proxy for intent.
