We have an event listing website and run Doubleclick for Publishers(small business) and I would like to have a home page slide show where paid slides alternate with non-paid slides. The paid slides will be clearly marked so. This will create a very valuable inbound links, for example for New Years Events. However, there is an opinion from another forum that we will be penalized in search engines if our ad content is indexed. I am confused as to why?
Thanks a lot.
