Kontera’s ContentLink service dynamically finds “contextually relevant keywords” on publishers’ web pages, which are then automatically turned into links. When a user mouses-over a link, an ad displays on the page. There are five different ContentLink ad formats – text only, text with an image, banner, video, and flash.
Many of Kontera’s publishers use the service as a compliment to AdSense. Checks are sent to publishers once a month, as long as they’ve earned $100 or more. Publishers can also edit the ContentLink tag to make sure ads match the layout of their site. In addition, Kontera offers a WordPress plugin to easily add ads to your blog.
For advertisers, a bidding system is used to determine ad placement. Kontera claims that their technology produces better relevancy & ROI.
