How do I serve multiple ads in a single zone?

Using the concept of "wrapper" ads, you can create an HTML banner which itself serves multiple ads.

The trick here is to generate the tags for each of the individual ads you want to be shown in by this zone.

For example:

1. Set up two zones both sized at 234x60
2. Link two (or more) ads to these zones.
3. Create a new HTML banner (468x60) and paste into it the invocation tags for the two 234x60 zones you created.

This will result in one 468x60 banner (which you can link to your website's 468x60 zone), which in turn serves up two of the 234x60 half-banners.

If you want to ensure that the same half-banner isn't repeated, you can enable the "Don't show the same banner again on the same page" option when you generate the half-banner zone tags.
