How to brief a marketing agency in one page
Write this before any call and you will get better proposals from everyone.
The six lines
Who you sell to. What you sell and the price. What a good customer is worth. What you spend on marketing today and what you get. The one result you want in ninety days. What you have already tried.
Rough numbers are fine. Honest numbers are better.
What to ask back
Ask any agency to show how they would measure the result, who will work on it by name, and what they will stop doing if it is not working.
