Demystifying "Above the Fold"
Read a great little piece about placing ads "above the fold"—that is, before readers have to click or scroll. Most people believe that's the best place for ads. This article, called "Demystifying 'Above the Fold'" is important to read for its contrarian approach to this belief. It states that people are often so intent on reading content may not notice any ads above the fold. Better places to insert them are at "action points" like Comments or Links.
