What I know is that they provide a natural language search tool directly from the Explorer address field. For example, if your IE has this plug-in, you can type in "plasma tv" and go directly to the one and only site that has purchased this phrase from them. Sort of like Google's "I'm Feeling Lucky". This plug-in apparently comes bundled with PCs purchased from Best Buy, among other ways it may show up on one's system.
In the case of the phrase he wants to sell me for $1500 a year, they got 4,000 searches last month. (No, I didn't ask why the previous owner got out!)
