Re: Ad Spend
"It's carefully tracked and if it didn't give value for money the advertisers would go out of business."
What is very unlikely to be tracked - and it's actually quite difficult to see how unless you actually listen to people like me telling you how they behave - is the people who walk because of it.
For example, yesterday I had to ring up my car insurer to give them an updated card number. The agent then promptly tried to upsell on other insurance products. That annoys me. When renewal time comes around I'll go elsewhere. It won't be the first time I've done that and I don't suppose it will be the last. Their marketing won't have the faintest idea that that's why they've lost this customer. They'll be able to show the positive results of their upselling but they won't know how many customers like me that they've lost. Their figures will be slanted to the optimistic side.
