When to stop advertising
Agencies rarely raise this because it reduces their own numbers. But there are situations where the correct advice is to turn the campaign off, and a trade that never pauses is usually burning money and goodwill at the same time.
When the diary is genuinely full
Advertising work you cannot start for two months produces frustrated callers who ring somebody else and remember that you wasted their time.
If you are booked out, either pause or change the message to lead times. The second is better — saying you are booking into November is credible, and it holds the people willing to wait.
When you cannot answer the phone
A campaign generating calls nobody picks up is the most expensive thing in small business marketing. Every unanswered call is a lead paid for and given away.
If you are on the tools all day with no one on the phone, fix that before adding budget. It is not a marketing problem and no campaign solves it.
When the season is wrong
Stoves in June. Exterior painting in December. Landscaping availability in August when you are full.
Spreading budget evenly across a year feels prudent and is usually the opposite, because it overspends in the months nobody is buying.
When it has not been given a chance
The opposite error, and more common. A campaign switched off after ten days has not finished learning and has told you nothing.
A month is the minimum before any judgement is worth making. Turning things off early and calling it a test is how most businesses conclude that advertising does not work for them.
