How long before advertising pays for itself
Paid advertising produces its first enquiries in days and its first reliable numbers in weeks. Judging it on the wrong day is how good accounts get switched off.
The first two weeks are about the machine
Campaigns go live, enquiries start arriving, and most of what you learn is operational: whether the replies work, whether the booking page is clear, whether your team can absorb the calls.
Cost per booking in this period is unreliable and usually high. It is the price of finding out which audiences and which messages deserve the budget.
Days thirty to sixty are the first honest read
By now there is enough volume to see which campaign produces appointments rather than enquiries, and the first kept visits have happened. This is where cost per booking starts to mean something and where budget should move towards what works.
This is also where the second problem appears for most businesses, which is not advertising at all: no-shows, slow replies in busy hours, a calendar with no room at the times people want.
Months three and four pay the invoice
Work bought in month one shows up as revenue later, especially where the sale starts with a consultation. A business judging month one by money in the bank will always conclude that advertising failed.
Match the period you judge against your own sales cycle. If a consultation becomes treatment three weeks later on average, then the honest review happens at the end of month two, not at the end of month one.
When to stop instead of waiting
Waiting is not always right. If after six weeks the cost of a booking is several times your ceiling and nothing about it is improving, the honest conclusion is that this channel does not work at your price point, and continuing is a donation.
The difference between patience and denial is whether the numbers are moving in the right direction. Flat for six weeks is an answer.
