We have rescued more campaigns with "call them within five minutes" than with any change made inside an ad account. It is not a clever insight and it is not ours. It is just the largest available lever that almost nobody pulls.
What actually happens in four hours
A person fills in a form on a Tuesday evening. They are, at that moment, more motivated than they will be again. They have a problem in mind and they have just decided to do something about it.
Then nothing happens. So they do the reasonable thing and fill in two more forms.
By the time you call on Wednesday morning, you are the third company to contact someone who has already had a conversation with the first. You are not selling your service any more; you are selling against a decision that is already forming.
Speed is not about being efficient. It is about arriving before your competitors have framed the decision.
Why it wrecks the ad reporting too
This is the part that gets missed. Slow response does not just cost you the booking — it corrupts the data the campaign learns from.
If you send conversions back to Meta when someone books, and bookings are suppressed by slow follow-up, then Meta is optimizing against a signal that reflects your front desk rather than your audience. The algorithm concludes that audiences are worse than they are and shifts spend accordingly.
Fix the response time and campaigns frequently improve without anyone touching the targeting, because the feedback signal finally describes reality.
What "five minutes" requires
Someone whose job it is. Not "whoever is free." A named person, with the notification on their phone, and a defined backup.
An immediate automated acknowledgement, and then a human. The auto-text buys you a few minutes of goodwill. It does not buy you the booking. Practices that stop at the automation see the same drop-off as practices that do nothing, slightly delayed.
A call, not just a text. Text as the fallback when the call is not answered — and the call should come first, because a missed call from a local number gets returned.
Out-of-hours honesty. If you cannot cover evenings, say so in the automated reply with a specific time. "We'll call you at 9am" is respected. Silence until 11am is not.
What we ask before we agree to run ads
Who answers the phone, how fast, and what happens at 7pm on a Saturday.
If the answer is "we check the inbox in the mornings," we say so plainly: spending money on ads before fixing that is buying leads in order to let them go cold. We would rather have that conversation before taking the budget than three months into a campaign that was never going to work.
It is not a popular thing to say to someone who wants to start advertising next week. It is the single most useful thing we know.
If you want to find out what your actual response time is, pull ten recent leads and check the timestamps against the first outbound contact. Most people are surprised, and not in the good direction.
