You should not duplicate a tag on a page. Why?
- The formats that have the same
ID will be “glued” to each other.
- The advertisers detect how many times the same format is present on a page. The revenue generated will simply be divided by the number of formats.
The solution is to use different formats offered by The Moneytizer. Therefore, on the same page, you can place a “top medium rectangle” and a “bottom medium rectangle” to optimize your monetization. Same for the megabanner format.
