How much time should you spend on a sales campaign?

This is an actual photo of our own Carl Markstrom wondering whether he ate breakfast. He scratched his head like this for hours.

It's a great question and thank you for it. The easy answer is until you have satisfied you inventory as well as your ad revenue goal. REMEMBER------- AD REVENUE GOAL SHOULD COVER ALL COSTS OF THE PROJECT (See: http://programbooktalk.blogspot.com/2012/02/real-measurement-of-happiness.html
But what is your organizations revenue goal for ad sales in the playbill? If you should you hit a certain level, should you stop??? Say in last Season's playbill your revenue was $33,000. Will you stop at $33,000 once you hit it for the next Season?  Perhaps and perhaps not. Here is a quick analysis of whether you should pursue more ad revenues. There are (2) elements to review. The first and most important is, How long did it take this Season versus last to achieve the $33,000? That is to say, look at the first sale from last season to the last sale of last Season. How long did it take??? Now apply that same formula to this next Season. Was the time shorter or longer? If it took longer this Season then this is an indication that the sales did not come as easy. The second element, and most important. Did I say the first one was most important? The truth: They are both most important. The second element is INVENTORY.

Do you have the surplus INVENTORY. 

See:http://programbooktalk.blogspot.com/2012/02/normal-0-false-false-false.html

So If you have the surplus inventory, regardless of the ease of sale, YOU MUST SELL TO THE INVENTORY SPACE. Now let us say that you have satisfied your inventory for the "perfect signature" and that it was a considerably longer sales campaign this Season. NO MORE ADS. SHUT OFF THE SALES MACHINE. If you have satisfied the inventory for the perfect signature and the length of the sales campaign was shorter, then go for it....ADD THE PAGES AND MAX OUT THAT EXTRA SIGNATURE WITH PRECIOUS AD SALES.
