# How fast do buying signals expire? A response window for each. A buying signal is a perishable thing. The same person, sent the same message, is a likely reply on Tuesday and a likely ignore the following Monday. Here is how long each signal lasts, and how to set up your week so you act inside the window. **The short answer:** **Buying signals expire** at very different speeds. First-party signals, such as an abandoned signup, a website visit, a profile view or a post engagement, go cold within hours to about four days. Trigger events last longer: a hiring signal lasts while the job is open, funding about 60 days, and a new leader roughly 90 days. The closer a signal is to you, the faster it fades. ## Signals decay because attention moves on, not because the need disappears. When someone views your profile, the problem you solve is in their head right now. A few days later it has been replaced by fifty other things. The need may still exist, but the moment where your message lands on top of their own thinking has passed. You are cold again. Trigger events decay differently. A new VP of Sales does not stop being new after three days. Their window closes when decisions get made: the stack is reviewed, the vendor is picked, the plan is set. That takes weeks or months, so the clock is slower. The closer the signal is to you, the faster it expires. ## The response windows, signal by signal. | Signal | Goes cold in | Act within | Clock type | | --- | --- | --- | --- | | Started a signup, didn't finish | Hours | Same day | Attention | | Website visitor (identified) | 1-2 days | Next morning | Attention | | Profile viewer | 1-3 days | 1 day | Attention | | Post engager | 2-4 days | 1-2 days | Attention | | Competitor post engager | 2-4 days | 1-2 days | Attention | | Page follower | 1-2 weeks | Within the week | Attention, slower | | Competitor follower | Weeks | When a second signal appears | Pool | | New in role | ~90 days | Weeks 3-8 in role | Decision | | Hiring for a role you help with | While the job is open | While open; repost is a good moment | Decision | | Funding round | ~60 days | Weeks 2-6 | Decision | These are working rules from running outbound, not lab measurements. Your market may run a bit faster or slower. The order almost never changes. ## There are three kinds of clock, and each one needs a different habit. Attention ### Act daily Viewers, engagers, visitors. The value drops every day you wait. Only a daily routine works. Decision ### Act in a window Job changes, hiring, funding. Being first is not the point; landing while decisions are open is. Day one is often too early. Pool ### Watch, don't send Followers of you or a competitor. A long list to hold until someone in it does something else. ## Speed beats polish, up to a point. On attention signals, a good message sent today beats a perfect message sent on Friday. Most teams get this backwards: they spend the week researching and drafting beautifully, and by the time it goes out the signal is gone. The rule we use: **if something has to give, cut the number of people, never the speed.** Ten well-timed messages beat forty late ones. That does not mean sending lazy messages fast. It means doing less research per person, aiming for one true, specific observation instead of five, and sending it while it still lands. On decision signals the trade-off flips. A funding round or a new leader gives you weeks, and the first wave of messages is the noisiest. There, take the time to read the announcement or the job ad properly. ## A daily rhythm that keeps you inside every window. ### Morning: pull yesterday's attention signals. Profile viewers, post engagers, competitor engagers and identified visitors from the last 24 hours. Fifteen minutes by hand. ### Morning: qualify and drop most of them. ICP check on every person. For a high-ticket offer, keeping roughly 10-30% is normal. ### Morning: research and send the survivors. One specific observation per person, message out the same day. This is the step that slips first when you are busy, and the one that matters most. ### Twice a week: check decision signals. New leaders in weeks three to eight, open or reposted roles, funding announcements from two to six weeks ago. Add the ones that fit to the week's list. ### Weekly: check the pools for second signals. Followers and saved accounts who did something new. Move them up. ### Friday: measure by signal. Reply rate and interested-reply rate per signal type. Drop sources that do not earn their place. By hand, the daily part takes about an hour. That is fine for twenty messages a day. Past that, most teams either automate the capture and drafting, with a tool such as [Valley](https://joinvalley.co/?utm_source=signalbasedoutbound), or let the routine slide to weekly, which quietly turns signal-based outbound back into cold outbound. ## Late is not the same as never. A signal that went cold is not wasted. It tells you a person or account was once interested. Two things to do with expired signals: - **Move them to a pool.** If they show a second signal later, they jump the queue. - **Treat them as a slightly warm cold lead.** Message them as you would anyone who fits your ICP, without any assumption that they are in market. What not to do: send a week-old profile viewer a message written as if they were curious today. The tone is wrong, and they can tell. ## How to tell if your pipeline is too slow. - Measure the gap between signal date and send date. For attention signals, the median should be under two days. - Compare reply rates for messages sent inside and outside the window. If they look the same, your capture dates may be wrong. - Check that new signals arrive every day. A broken feed looks exactly like a quiet week. ### How quickly should I respond to a buying signal? Within a day for profile views, website visits and post engagement. Weeks, not days, for job changes, hiring and funding, which have longer decision windows. ### Is it too late to message someone who viewed my profile last week? For timing purposes, yes. Treat them as a normal prospect who fits your ICP, and do not write as if they were curious today. ### Why do website visits expire faster than funding signals? A visit reflects attention, which moves on in days. Funding reflects a decision window, which stays open until the money is allocated.
