What is the best way to manage advertising on a site, where you designate an area on a all pages and control the advertising in that area on all the pages. Thanks
That's quite a broad question you are asking. If I understand your question, personally, I use agencies such as Google AdSense and Tribalfusion to sell adverts on my behalf and have a freelance salesman to sell whenever possible. I don't like to get too involved in the sales process personally.
