Perfecting the copy in our advertising

Hi. As you’ve probably noticed by now we’ve been in the process of improving our advertising for quite some time now. We now have a large database of advertising possibilities for your use.
When designing new advertising there are two stages – a formative stage – where one creates, and a summative stage – where one tracks and monitors how the advertising is going.
We’re working on improving the text in our advertising. One of the ways that we are doing this involves your help.
What text is working best in your advertisements? What ads have pulled exceptionally well for you, and what ads have been a dud? Really any advise on the effectiveness of our advertising, or any apparent needs you see in our advertising will be very helpful.
We have a unique resource in the fact that we have access to each other’s knowledge. This is a wide research and study base. For it to work, though, I need as much feedback from you guys as possible. I look forward to hearing your thought and comments.
