In my last post I was talking about the importance of a good segmented database in e-mail. This is also true for other media too.

Take for instance banners and on-line advertising.

Now, you're probably wondering "Why in earth should I segment my banner advertising?, There is no database in this case...". And probably you'd be right. But if you offer different discounts to different targets you must be pretty sure that you segment the different ads so that they do not show up at the same time in the same portal or webpage.

Take this example I've seen in The daily WTF:

Am I right when I say that you must be careful even with banners? ;-)
