How to stop wasting money on advertising

There was a classic statement from a company executive I read once (can’t remember who) that said, “I know we waste 50% of the money we spend on advertising, I just don’t know which 50%”.

That might be okay, but not ideal, if you are a big company with a big marketing budget. Most of my clients don’t fall into that category, so I am insistent that money spent of direct advertising is as effective as possible and is intended to generate an action or response by a prospect.
