How to purchase online advertising space

Purchasing online advertising space can be done a few different ways. If you want to advertise on a specific website, contact their advertising manager and ask for rates and availability of ad space. To advertise over a network of websites, contact different companies who manage website networks such as Tribal Fusion or Doubleclick. They will be able to provide you with advertising rates and targeting possibilities. The final way is to work with an advertising agency that has a relationship with online publishers. Often times they can negotiate the best rates and steer you in the right direction if you are new to advertising online.
